About

Professional summary

I am a Senior Full-Stack and AI Engineer with more than five years of experience building scalable fintech, blockchain, AI-agent, and cloud-native products. I deliver applications across web, mobile, backend, and serverless environments.

I specialize in architecting distributed systems, developing intelligent agent workflows with LangGraph, and building secure digital asset infrastructure. My work spans prediction markets, decentralized finance, stablecoin operations, wallet systems, and blockchain transaction workflows.

I have led critical engineering initiatives from concept through production, including platforms that process more than $200M in transaction volume. I am comfortable owning product architecture, frontend and backend delivery, infrastructure, integrations, and technical execution as a sole engineer or senior contributor.

I have built AI-powered systems using LangGraph, MongoDB persistence, asynchronous job orchestration, and natural-language transaction execution. I also have hands-on experience with Solana, Cardano, smart wallets, self-custodied wallets, MPC custody systems, and secure blockchain signing services.

My technical background includes TypeScript, Python, React, React Native, Next.js, NestJS, Node.js, AWS serverless services, Docker, Kubernetes, and modern cloud platforms. I enjoy building reliable, user-focused products that simplify complex financial, healthcare, and telecommunications workflows.
