    I’m spinning up a new enterprise deployment of Omnissa / VMware Workspace ONE and need a senior engineer who can own the entire UEM lifecycle from architecture through steady-state support. The environment spans Windows, iOS, Android and macOS devices, so you must be equally comfortable writing custom profiles for iOS as you are managing Windows patch rings or Android Work Profiles. Beyond the core console work, deep integration with the following is critical: • AD, Exchange, PKI, certificates, VPN High-availability design, DMZ and firewall rule-sets, unified application cataloguing, device enrollment flows, compliance policies and large-scale production rollouts all fall inside the scope. You will document everything you build and walk my internal admins th...

    I need a clear, data-driven plan—and the hands-on execution—to lift revenue generated by our existing iOS / Android app. The product is live and stable; now the priority is tightening every step of the purchase journey so more installs turn into paying customers and existing users buy more often. To make that happen, the work will cover both strategy and implementation. Expect to dig into our current analytics stack (Firebase, Mixpanel, GA4), map the conversion funnel, and pinpoint friction points in onboarding, checkout, and in-app messaging. Once the quick wins are identified, I want A/B tests rolled out, push-notification campaigns scheduled, and any necessary UI or paywall tweaks coded, QA’d, and shipped to the stores.

    I am launching a scalable e-commerce marketplace and need the complete mobile application built for both iOS and Android. The first milestone centres on three core capabilities that must be production-ready from day one: • Secure user authentication – email or social sign-in, token refresh, and logout flows handled safely. • Seamless payment gateway integration – in-app checkout that passes all compliance tests and returns clear transaction states to the UI. • Product reviews – verified purchasers can post ratings and comments that update instantly across devices. Wireframes and an API (REST/GraphQL) are already in motion, so your focus will be the full mobile build, state management, and preparing store-ready releases. Clean architecture, mo...

    The objective is straightforward: drive qualified leads to my e-commerce store through highly focused Google Ads campaigns. I already know which products convert best, so the work will centre on just a handful of flagship SKUs rather than the full catalogue. I need the campaigns structured for maximum relevance—tight keyword groupings, compelling ad copy, and conversion-optimised landing pages—so every click pushes the prospect toward a signup or purchase enquiry. Smart Bidding, negative keyword pruning, and audience remarketing should all be part of the strategy to keep cost-per-lead efficient. Tag installation and event tracking must feed clean data back into Google Ads and Google Analytics so we can refine performance weekly. Deliverables • Campaign build...

The user flow is simple: type or paste a question such as “show me all orders placed this week,” tap a button, and instantly receive a correctly formatted SQL query. From there the query should be easy to copy, share, or save. Cross-platform consistency is essential, so the build must target iOS and Android from the same codebase. React Native or Flutter are both fine; feel free to suggest an alternative if it still produces App Store- and Google Play-compliant release builds.

    I’m looking for someone who already knows GoHighLevel inside out to help me build a complete, revenue-focused sales funnel. The objective is straightforward: turn visitors into paying customers. I have my product details, branding assets, and copy drafts ready; what’s missing is the technical wiring and strategic flow that makes the funnel convert. Here’s what I need from you: • Map and create each funnel step inside GoHighLevel, including opt-in, sales, order-bump, and upsell pages. • Configure automations (email, SMS, voicemail drops) that nurture prospects and push them toward checkout. • Set up payment integrations and ensure transactions run smoothly from the first click through confirmation. • Install tracking (GHL, Facebook...

    I run a catalogue of digital downloads on Payhip and I need an affiliate manager who can steadily turn TikTok into my main sales channel. The objective is simple and measurable: drive more paid conversions, not just views or likes. You will focus on the U.S. creator space—identifying suitable TikTok accounts, handling the outreach, negotiating the commission split inside Payhip’s built-in affiliate dashboard, and then nurturing the relationship so each creator keeps posting and improving results. Because Payhip automates tracking, payments and coupon codes, your time can go almost entirely into recruitment, content coordination and performance analysis. Daily tasks include: • Sourcing and vetting creators who match my audience and product niche • Crafting...

    I want to launch an Android and iOS application that mirrors the core experience of Bubbly Live—real-time streaming, one-to-one video calls, and virtual gifting—while still carrying my own branding touches. The interface should feel instantly familiar to regular Bubbly users, yet stand apart through subtle design tweaks that we will define together (think updated colours, iconography, and motion cues rather than a full layout overhaul). Core scope • Low-latency live streaming rooms that support thousands of concurrent viewers. • One-to-one video calling initiated either from a stream or directly from a user profile. • Gift-sending system with animated effects and a creator revenue share logic. • In-app wallet and consumable coin balance, incl...

    I’m ready to launch an online store and need a developer who can take the idea from concept to a fully live, revenue-generating site. The single, clear objective is to sell products and services directly to customers, so every decision—from information architecture to checkout flow—should push conversion rates upward. I have not locked myself into any specific platform; I’m open to WordPress + WooCommerce, Shopify, or a completely custom build if you can justify why it offers a better path to scale, speed, or unique functionality. Pitch me the stack you believe will deliver the smoothest user experience and be simplest for me to maintain. Key things I’ll be looking for: • A modern, responsive storefront that looks sharp on mobile and desktop &b...
