I’m building a premium learning experience that streams protected video lessons to both iOS and Android users. Every clip needs to stay locked inside the app—no easy downloading, screen-recording or link sharing—so I’m looking for a developer who already knows their way around secure video delivery (tokenised URLs, DRM, HLS encryption or comparable methods). Core requirements • Native or cross-platform build targeting iOS and Android from a single codebase • Robust subscription engine so I can switch between monthly, yearly or other tiers without shipping new versions • Two-factor authentication for every login, alongside the usual email / password flow • Lightweight admin panel where I can upload videos, tag them into courses, set prici...

I’m building a self-contained virtual core that runs cleanly from Android 9 through 17. The goal is to let any embedded game call the native Facebook, Twitter, Google or other social-login SDKs directly, with zero crashes and the same frame-rate smoothness you would expect on a physical device. No standard “virtual SDK” tricks—I need an isolated space that looks and behaves like genuine Android, yet never bleeds into the host environment. Security is critical. The core must slide past ACE checks and similar anti-tamper routines, all while a custom licensing layer keeps tight control over which apps can launch inside. My model blocks by both package name and visible app name, and I’ll cap the total number of authorised packages. If someone tries to exceed that...

I need a fully-featured card payment gateway for our UK customers that diverts every authorised transaction straight into USDC, landing in our wallet the moment the payment is accepted. Three things are non-negotiable: the customer’s statement must carry our company name, settlements have to happen instantly in stable coin, and the whole flow should be built to keep chargebacks to an absolute minimum, and GBP showing in customers banks statement, as a-pose USD, as these are uk customers, Because traditional acquirers such as Stripe, Worldpay and similar platforms have frozen or delayed funds in the past, I want this solution engineered outside that ecosystem. PCI-level security, strong customer authentication (3-D Secure or equivalent) and any other anti-fraud layers you recommend ...

Developer Needed – Lean MVP Build for Marketplace Startup (Circulate) Project Overview I’m building a startup called Circulate. Circulate is a local marketplace platform where users trade goods and services using an internal credit wallet system instead of cash.

I want to use existing integrations/services wherever practical to keep development time and costs low. ________________________________________ Core Concept Users trade using internal platform credits instead of cash. Rules: • every user starts at 0 credits • users can spend down to a controlled negative balance (exam...

I’m turning my scripted Minecraft world, Yeti SMP, into an experience that feels just like Unstable SMP, and I need a developer (or small team) who can take full ownership of the server side of things. The build starts with provisioning and running a rock-solid Java server, then layering in every feature that makes Unstable so much fun: • Custom plugins tailored for our lore-driven events • Hardened security to keep griefers and exploits out • Robust user-management tools so my content creators can focus on recording rather than policing players On the admin side I rely heavily on: • World-editing tools (FastAsyncWorldEdit, VoxelSniper or similar) for quick set builds • Fine-grained permission management (LuckPerms level control) • Real-...

I need a full stack developer and Android app specialist to create a falls management social care application. We’re building a system that places NFC tags where care happens — on residents’ mobility aids (where present), bed-frames, and door-frames, with an optional consent-driven silicone wristband.

We’re seeking proposals to build this in three potential phases. You may quote for any one phase, multiple phases, or all three. Project context The problem Falls in UK care homes drive 255,000 emergency hospital admissions per year and cost the NHS £2.3 billion. The single b...

The goal is straightforward: replace the current username/password flow with secure SSO through Google, Facebook, and LinkedIn.

I want a seasoned security professional to probe my site from every angle and show me—plainly—where a hacker would slip in. My main worry is outright breaches, not just compliance check-boxes, and at the moment I only have the usual basic plugins and a standard SSL certificate in place.
