We are looking for an experienced Frontend Developer to build a modern, high-performance responsive website using React and TypeScript. The website must work seamlessly across all devices — desktop, tablet, and mobile — and follow best practices for UI/UX, performance, and maintainability. This project focuses on delivering a scalable, clean, and production-ready frontend that can later be extended into a mobile application if required. My preferred styling stack is Tailwind CSS combined with HeadlessUI and shadcnUI components; if you see gaps or have performance-oriented tweaks within that ecosystem, I’m happy to discuss. Two interaction patterns matter most to this release: • robust form validation that surfaces errors instantly and accessibly, and ...

Fix: Production Blank Screen on Replit-Deployed Full-Stack App (Dev Works Fine) Tech Stack: React 19, Vite 7, TailwindCSS 4, Node.js 20, Express 4, TypeScript, PostgreSQL (Neon), Drizzle ORM. Hosted on Replit (Autoscale deployment). The Problem: The app works perfectly in development mode, but after deploying to production on Replit, the browser shows a blank/white screen. No visible errors in the browser console (or provide any you do see). Build Process: Vite builds the frontend to dist/public, esbuild bundles the server to dist/index.js. Express serves the static files in production. The build command is npm run build && npm run db:push, and the production run command is node dist/index.js. What I Need: Diagnose why the production build renders a blank screen Fix the...

My immediate goal is to stand up a proof-of-concept chatbot that can reason over structured data stored in a SQL database, surface answers in natural language, and be easy for me to extend later. Here is what I’m after: • Pick and wire up an open-source autonomous-agent framework (LangChain, AgentGPT, SuperAGI or a comparable option you trust). • Expose a clean TypeScript interface so the rest of my app can call the agent with a prompt and receive a streamed response. • In Python, configure the agent’s toolset to pull data from my existing Postgres tables, run simple analytic queries...

I’m assembling a freelance roster of seasoned Solana engineers to push a new decentralised application from idea to mainnet. The role centres on end-to-end DApp development: writing and auditing on-chain Rust programs, wiring them to a TypeScript/React front-end through Anchor or @solana/, and handling deployment, testing and optimisation so the final product is fast and fee-efficient. If you have shipped production Solana work before, please include links or GitHub repos that clearly show what you built and the parts you owned. I’ll review those examples first to decide who moves forward. We will work milestone-by-milestone; as soon as the initial scope is delivered (fully functional features, commented code, concise hand-off docs), I have follow-up tasks ready. Comfo...

I maintain a Node.js / TypeScript code-base that submits Jito bundles to the Solana network at high frequency. The current version works, yet under heavy load it saturates network bandwidth, slows slot confirmation, and leaves a larger attack surface than I’m comfortable with. I’d like you to jump in, profile the pipeline, and return an implementation that is measurably better across three axes—performance, scalability, and security. What performance means here is simple: bundles must reach the leader faster so more of them land profitably. I’m especially keen on lowering the chatter between my service and Jito’s relays so network bandwidth is used far more efficiently. You’ll have full access to the existing TypeScript modules, aggregato...

I need a backend engineer to turn my spec into an MVP that exposes a clean, API-first trust and reputation service for autonomous AI agents. The entire product lives server-side—no front-end work at all—so every feature must be reachable through intuitive, well-documented endpoints. Core requirements • Stack: your choice of FastAPI (Python) or Node (TypeScript), backed by Postgres, containerised with Docker, and wired to Stripe for billing events. • Auth: simple, robust API Key flow; keys must be generated, stored, and validated on every request. • Scoring logic: compute each agent’s trust score solely from its interaction history, according to the formulas in the spec. Performance metrics or direct user feedback are outside this first itera...
