Title: Build a fast Rust or Go backend API

I'll design and build a production-ready backend API in Rust or Go — clean architecture, proper error handling, tests, and documentation included. Whether you need a REST or gRPC service, I focus on performance, maintainability, and code that holds up under real traffic. Ideal for startups and teams that need a reliable, fast core to build on. You'll get well-structured, documented code you can hand to any developer.

Title: Database design & backend performance optimization

Slow queries, a data model that doesn't scale, or a write path that can't keep up? I'll design your schema, build a storage or caching layer, or optimize existing bottlenecks. I've built a time-series database and a distributed key-value store from scratch in Rust, so I understand what's actually happening under the hood — not just which library to call. You'll get measurable improvements and a clear explanation of what changed and why.

Title: Full-stack web app — built, deployed & working

Need the whole thing shipped, not just a backend? I build complete web applications end-to-end — React frontend, backend, database, and deployment with a custom domain and HTTPS. I've shipped a live SaaS product with real users, so I know how to take an idea from zero to a working app people actually use. You'll get a deployed, functioning product, not a half-finished prototype.

Title: Add AI to your product — RAG, agents & LLM features

I'll add AI capabilities to your product — retrieval-augmented generation (RAG), an agent workflow, or an LLM integration — wired into a real backend, not a throwaway notebook. I've built multiple AI frameworks and shipped an open-source AI assistant, so I handle the full path: prompt design, retrieval, API integration, and production deployment. You'll get a working AI feature your users can actually use.
