i want to create MS Access database sheet requirement database not to big or hard Database Requirement Explanation I belong to the Indian Army. My unit has a strength of approximately 445 personnel. Every year, individuals remain embodied (on service) and disembodied (service break) for varying periods, usually ranging from 1 to 4 months at a time. I want to create a database (preferably in MS Access) where each individual has a separate profile, and all service periods are calculated automatically. ⸻ Individual Profile Requirements Each individual profile should contain: • Army Number • Rank • Name • Date of Enrollment Example: Army No: 1245 Rank: Sepoy Name: Pankaj Date of Enrollment: 01 Dec 2015 ⸻ Embodiment / Disembodiment Logic For each individual, there can be m...

I want a purpose-built Airtable base that lets my project managers track every $ that flows through a job while giving me, as the owner, a clear tick-off control for supplier payments. What the base must do • Cost management and calculations – an input for estimated cost, an input for actual cost, and an automatic profit-margin field that updates in real time. • Supplier quote storage and attachments – each cost line needs an upload field (PDF, image, email printout) so the original quote is always one click away. • Payment tracking – a simple checkbox or single-select that I can toggle when a quote has been paid; when selected, it should stamp the payment date automatically. Financial insight I rely on profit-margin reports, so the system sho...

I’m rolling out the first release of a job-searching platform that already sits on top of a community of 87 million professionals. The entire focus of this build is to let candidates search and discover employer-posted opportunities quickly and intuitively. Core scope • Job listings are the single feature we need live for launch. Employers must be able to create, edit, publish, and archive their openings through a straightforward dashboard, while seekers browse, filter, and save roles. • Only direct employers will post ads in this phase. The workflow has to reflect that—no agency fields, fees, or approval steps. • Clean, responsive UI that feels inviting to a global audience and scales to the size of our network. • Solid search & filter logic (k...

The goal is to create a web-based Applicant Tracking System that lets employers publish vacancies and follow every candidate from application to final decision. I only need two roles at this stage—Admin (full system control) and Employer (job and applicant management)—so please keep the interface and permissions model focused on those. Core functions I expect • Job Posting: easy form to publish, edit, archive, and reactivate openings, with searchable listings for the employer dashboard. • Candidate Tracking: status pipeline, notes, and simple reporting so an employer can see where every applicant stands at a glance. • Admin Console: manage employers, adjust fields/workflows, and pull high-level metrics.

I have several disparate sources holding our inventory information and I want it all pulled together into one clean, well-structured Microsoft SQL Server database file. The job is straightforward in principle: extract every piece of inventory data you can reach, reconcile duplicate SKUs or mismatched item descriptions, then load the final result into a single .sql or .bak file that I can restore through SQL Server Management Studio. Please preserve every existing field that carries operational value—quantities on hand, reorder thresholds, location codes, cost figures, and any audit timestamps—and normalise the schema where it clearly improves reporting speed or data integrity. If a field appears under different names in different systems, map it consistently; if you uncover ga...

I want to demonstrate provable data consistency across a geographically distributed Hyperledger Fabric network by persisting the blockchain ledger in CockroachDB instead of the default back-end. The work centres on two Fabric layers: chaincode and the ledger itself. Chaincode reads and writes must be routed so that every block committed by a peer is durably stored in CockroachDB, and peers must replay that data with no divergence even under node failure or network partitions. The scope includes mapping Fabric’s block and state data structures to a CockroachDB schema, wiring the peer so that commit and endorsement steps call the database seamlessly, and validating the design with a small multi-region testnet. CockroachDB will act strictly as the ledger store; MSP and other services r...

I’m looking for a seasoned full-stack professional who can guide me through deep-dive, project-driven sessions that sharpen every layer of web development. My foundation is already advanced, but I want to refine technique and architecture across the whole stack—from pixel-perfect React front ends to robust Django APIs and well-designed relational databases. Here’s what I need from you: • short, structured video calls (ideally 2–3 times a week) where we dissect real-world problems and pair-program solutions • code reviews that push me toward cleaner patterns, stronger testing habits, and production-ready deployment workflows • mini-projects or exercises that tie together JavaScript/React, Python/Django, HTML, CSS, and any supporting language or ...

I’m running a web application on a custom-built PHP framework and it currently sits on an ageing database that I now want fully migrated to MySQL. The job is strictly a database migration—no codebase refactor is required at this stage—so the focus is on cleanly lifting all existing data structures and records into a fresh MySQL schema while keeping the application functional throughout the transition. What I’ll hand over: the current schema dump (or direct access if you prefer), sample data, and a brief outline of the application’s data flow so you can map dependencies accurately. What I expect back: • A MySQL-ready schema that mirrors the original structure, optimised where obvious gains are available (indexes, data types, constraints). • Reli...

I’m building an end-to-end lending experience for iOS that feels as smooth as Slice or Moneyview. The job covers both sides of the stack: a sleek native iOS front end and a secure, scalable back end with the APIs that power it. On the user side the flow is simple but must be rock-solid. A new customer signs up with email/password, can just as easily use a social account, and once inside can enable Face ID or Touch ID so returning is frictionless. They complete a loan application form, the system instantly checks eligibility, returns an approved amount (or declination), shows a clear repayment schedule, and later lets them review every past loan in a dedicated history screen. I need the full technical delivery: • iOS app (Swift or SwiftUI preferred) that implements the entire j...

I’m ready to launch a niche marketplace where people can buy and sell live one-on-one skills. To keep future growth stress-free, I need the entire site built from scratch rather than on WordPress or a SaaS platform. Social-media logins should handle authentication out of the box, and CCBill will be the sole payment gateway. Here’s the core interaction I want implemented: I need it to be desktop and mobile friendly • Buyers browse a listed skill, pick an available time, and send a booking request. • Sellers can accept, decline, or counter with a new time until they finally hit Approve. • Once approved, CCBill charges the buyer automatically and both parties receive real-time alerts by text, email. Although we’ll launch with just two skills, the underlying...
