What I'm looking for

I seek roles where I can build scalable AI-enabled platforms and full‑stack products, mentor teams, and deliver secure, high‑performance solutions in a collaborative remote environment.

I am a Senior Software Engineer with over 10 years of experience delivering full‑stack solutions across AI infrastructure, web, and mobile platforms. I specialize in TypeScript, Node.js backends, and React front ends, and I build maintainable, modular systems that scale.

At Naptha I helped build AgentFlow Hub, a modular platform for managing millions of AI agents, designed TypeGraphQL APIs, and implemented an AI-powered analytics pipeline that improved task completion efficiency by 25%.

Previously at Metova and Automattic I delivered healthcare, fintech, e-commerce, and IoT projects with React, React Native, PostgreSQL, and GraphQL, improved dashboard responsiveness and retention, and automated CI/CD to reduce deployment time.

I mentor junior engineers, optimize databases and backend services for high concurrency, and am passionate about applying NLP, multi-agent systems, and automation to solve real business problems while maintaining security and performance standards.
