I build Web3 fintech products at Antier Solutions, including Gems Trade, a high-volume cryptocurrency trading platform. I design Rails REST APIs, implement complex trading-domain logic, and connect blockchain workflows to responsive user experiences.

I've integrated MEXC for liquidity, order-book depth, and pricing, and built an end-to-end Ondo on-chain asset conversion flow. Through caching, refactoring, eager loading, and query optimisation, I've improved application speed by 30% while supporting large trading and market-data workloads.

Before Antier, I worked on Makerble's Progress Boards analytics tool and developed Jameen, a React and Ruby on Rails SaaS management system. My work spans data modelling, API endpoints, React interfaces, authentication, reporting, and performance improvements.

I also build AI products independently, including a complete RAG assistant with FastAPI, React, vector retrieval, DuckDuckGo search, and a locally hosted Qwen2.5 model through Ollama. I use AI-assisted tooling to move quickly while retaining ownership of architecture, debugging, and delivery.
