Admin workflow I need an internal dashboard where I can: – Add or edit game packages...

Developer Brief Build a secure, cloud-based sports performance data platform that consolidates data from multiple technology providers into one dashboard. This is an example dashboard I have built The initial scope is to integrate Catapult Sports, VALD, and Teamworks. The platform must support both API-based data ingestion and manual or automated uploads of Excel/CSV files. API connections should retrieve approved data on a scheduled basis, while spreadsheet imports should validate, map, and standardise fields before storage. Create a central database with a consistent athlete profile and identifiers, enabling data to be matched across systems. Athlete matching should prioritise unique IDs and verified email addresses, with an administrator review process for unmatched or duplicate rec...

Our production platform is built on Node.js and I’m looking for someone who can step in as a long-term partner to keep it healthy while steadily making it better. Day-to-day you’ll be digging into three broad areas: • Fixing bugs as they surface so the system remains stable. • Profiling and tuning performance to keep response times low, memory use under control, and throughput high. • Enhancing existing features—polishing the user interface, tightening up backend logic, and refining the data-processing layer whenever we see an opportunity. Most of the work is about improving what already exists rather than building brand-new modules, so an eye for incremental refactorings, clean code, and solid test coverage is essential. I’ll share a prioritize...

I have a pre-launch adult fiction web app which writes adult type stories. Nothing is live yet. No users, no revenue, no traffic. I am looking for one engineer to take it from where it is to a working production launch. The stack: React 18, TypeScript, Vite and Tailwind on the front end (originally built in Bolt). Supabase on the back end, meaning Postgres, auth, private storage, Edge Functions, and RLS on every table. The app takes a user prompt and generates a text story, plus audio narration. I have a complete engineering spec in a single file, written to be built from directly. It covers the schema, the phase by phase build order, API contracts, error handling, rate limits, and what done looks like for each phase. I have already audited the repo against that spec, so the gaps are kno...

I’m rebuilding a web application from scratch and need a seasoned JavaScript developer who is equally comfortable on the browser and in Node.js. On the front-end I want clean, intuitive screens, a fully responsive layout, and smooth API integration. I’ll rely on you not only to code those pieces but also to show me the best way to push user-generated data up to a database. Server-side, you’ll wire everything together in Node.js and expose the endpoints the UI depends on. Part of the work involves calling Claude AI, so familiarity with its SDK, streaming responses, and prompt design will save us a lot of trial and error. I haven’t settled on a data store yet—SQL or NoSQL are both on the table—so I’d value your guidance on choosing and provisio...

My application relies on Apache PDFBox for generating and displaying PDFs, but the current build renders pages with an incorrect layout— it renders over other components in user interface. I need a developer who knows the internals of PDFBox, its Renderer (PDPageContentStream, PageDrawer, etc.), and the Java graphics pipeline to identify and patch the root cause of this layout problem. The problems is related to -method. It may be reproduced by adding a JSplitpane into a JFrame, then rendering to the left component. It renders over the right component, too. It is wrong. It also relates to PageDrawer and its setClip() -method. Even if we apply the initial clip, it still renders wrong, see code below. AffineTransform at = (); (); Shape shape = (initialClip); (shape); Moreover, if w...

I need an experienced hand to stand up a fully working Claude Code project that runs an agentic coding loop on top of Claude code. Full orchestration. The outcome I’m after is a repeatable template where the system knows exactly when to call Fable and Opus, with effort levels and the underlying resource allocation logic is clean and obvious.

New Freelancer with experience needed. Pakistan, India and Bangladesh freealncer. I run a Laravel API with a React JS frontend and it’s starting to show its age. I want an experienced developer to go through both layers and leave me with a lean, well-structured codebase that is easier to maintain and noticeably faster for end-users. On the React side the focus is pure code cleanup and refactoring: removing dead or duplicated code, splitting oversized components, introducing reusable hooks where they make sense, tightening up state management, and making sure the build stays light. ESLint, Prettier and whatever other tooling you normally use are welcome as long as the result is a tidy, readable repository. The Laravel backend also needs a careful once-over. I’m mainly after cl...

My ride-hailing and delivery platform serves about 7,500 registered users and thousands of completed trips, all running on a Laravel backend with customer and driver apps in Flutter. Lately each ride is costing an extra dollar or two purely in Google Maps fees, which is eating into margins. From the data I can see, the backend server appears to be the main culprit for redundant requests. I need a developer who knows both Laravel and Flutter—and who has already tamed runaway Google Maps usage—to step in, audit the codebase, and bring those costs back under control. Scope of work • Trace every Maps call issued by the backend and the two apps, identify duplication or unnecessary refresh loops, and map out the call flow. • Propose and implement smarter strategies su...

I want to launch a fully-functional platform where people can browse, book, and interact with “rental boyfriends” online. The core build should cover partner and client registration, profile pages with photos and bios, a simple booking flow, secure payment handling, and real-time chat or messaging so sessions can be coordinated smoothly. The interface must look contemporary on desktop and mobile, load fast, and remain intuitive for first-time users. You are free to suggest the best tech stack, but I’m leaning toward a mainstream framework (React or Vue for the front end, Node/Express or Laravel for the back end) so future maintenance is straightforward. A clean API layer is important because I plan to add a mobile app later. Key deliverables: • Responsive web app (...

I am building a free-space optical communications platform and need a complete pointing, acquisition, and tracking software package that can consistently maintain sub-degree alignment between my optical terminal and a remote node. Core expectations • Pointing accuracy: better than 0.5° under nominal environmental conditions; 100% uptime once locked. • Communications interface: native Ethernet/IP for command, telemetry, and reporting status. • Platform: x86/Linux preferred; however, I can compile on other POSIX systems if the code is portable. Your solution should include: 1. Real-time control loop that accepts attitude sensor data (e.g., IMU, encoders) and drives two-axis galvanometers and a MEMs array. 2. Acquisition logic capable of coarse scan, fine sc...

I’m in the planning phase of a Solid-style decentralized platform and need an experienced architect to sanity-check my approach. My main objective is to give users maximum data privacy and control, so every design decision—from pod storage layout to access-control mechanisms—has to reinforce that goal. What I expect from you • A short, focused consultation (chat or call) where I can run through my proposed architecture, data flow, and auth workflow. • Clear, actionable feedback on how to tighten privacy, avoid common Solid pitfalls, and keep the system modular for future scaling. • Pointers to best-practice specs, libraries, or reference implementations that would speed up development. If you’ve designed or audited Solid pods, WebID-OIDC f...

I’m upgrading our Laravel-based CRM so every client company can plug in its own WhatsApp Business number through Meta’s official Cloud API, not a reseller platform. The job starts with setting up Meta Embedded Signup inside our app, continues through webhook handling and message-template management, and ends with production-ready token storage that survives refreshes and keeps each tenant isolated. You’ll be working on: • Meta Embedded Signup flow embedded in our existing onboarding wizard • Webhook endpoints that route messages and events to the correct tenant context • Template creation, approval syncing, and marketing-style broadcast support inside the CRM UI • Secure, encrypted token lifecycle management for multiple numbers across compa...

Looking for a developer experienced with Adobe's UXP extensibility platform (or willing to learn it quickly — it's HTML/CSS/JS-based) to take a working panel prototype further. I have a functioning starting point: a UXP panel for Premiere Pro that displays mock clip-status data with a clean visual design already built. The next phase is connecting it to a real backend via API calls — pulling actual clip data from the active Premiere sequence using Premiere's UXP host API (the ppro object model), matching clips by filename/metadata against records from an external service, and displaying live status instead of mock data. This is a small, well-scoped project — not an open-ended engagement. Ideal for someone who's built UXP or CEP panels before, or has ...

I’m building the first release of my stock-trading platform, “Trade for Tomorrow,” and the immediate priority is to wire in reliable, ultra-low-latency market data for both the NYSE and NASDAQ.

The work described here adds a new UI-driven workflow for triggering those re...

I need a straightforward, standalone two-tier MLM system that will sell a single $9 product. The core of the job is to let every buyer automatically become an affiliate, earn on two levels, and see exactly what is happening with their network and commissions. Scope of work • Referral tracking – unique links or codes generated at sign-up and logged through to purchase on both levels. • Commission calculation – automatic, tier-based payouts that I can adjust from an admin panel. • User dashboard – clean, mobile-friendly view of referrals, sales, and earned commissions, plus the ability to copy their link. It can be custom-built or use an off-the-shelf framework if that speeds things up; the system simply needs to run on its own server without tying in...

I need a web-based platform that turns every dynamic QR code into a rich landing experience focused on product-demonstration video. When a customer scans the code, the page should autoplay the video in a clean, mobile-first viewer and immediately draw attention with interactive hotspots (think tap-to-reveal specs or 360° spins) and clearly placed related-product links that keep them exploring our catalogue without leaving the page. Core flow • I generate or upload a video and the system delivers a unique, trackable QR code for it. • The scan opens a branded microsite: hero video on top, interactive overlays layered on cue points, and a section below that surfaces complementary items. • All events—scans, plays, taps, link clicks, session time—feed a das...

I need a NetSuite-based portal where my resellers, distributors and suppliers sign in with their own credentials, see the price book and discount structure tied to their subsidiary/partner record, and place orders manually. Inside the portal they should be able to: • Search or browse our existing item catalogue, add products to a cart, and submit the order. • See real-time, partner-specific pricing that draws from individual price levels or discount fields already stored in NetSuite. • Have the submitted cart convert to a native NetSuite Sales Order, linked back to the partner record for reporting and fulfilment. Security must follow NetSuite’s role permissions so each partner views only their information. I’m comfortable keeping product maintenance in t...

We are looking for an experienced full-stack developer or development team to build a production-ready e-commerce platform with a unique Sales Partner system. This is NOT a standard e-commerce website. The initial products will be physical products such as watches, but the system must be configurable so products, categories, prices, stock and commission structures can be changed easily from the admin panel.

I need a secure, clinician-facing web application that lets authorised prescribers create a digital prescription, apply a legally valid electronic signature, and transmit the order straight to my GPhC-registered pharmacy for tracked-courier fulfilment. Primary users will be general practitioners and independent prescribers, who need to create an account and have their licence verified before being able to prescribe. The flow should be simple—search or add a patient, create a prescription, sign, and click “send”. Behind the scenes the platform should store an immutable audit trail, maintain patient records, and push the signed prescription to the pharmacy via secure API (FHIR, HL7 or a custom JSON schema—happy to discuss the best fit). Key requirements • Dig...
