About

Professional summary

I am a senior software engineer and technical lead with extensive experience building scalable web applications, backend services, and full-stack products.

My background is centered on Node.js, Ruby on Rails, TypeScript, React, Next.js, and distributed system design, with a strong focus on performance, maintainability, and product delivery.

I have led engineering efforts across startups, consultancies, and remote international teams, contributing to architecture decisions, team guidance, and implementation of production-grade systems.

I enjoy working on complex backend challenges such as APIs, background jobs, message queues, database optimization, and cloud infrastructure, while also contributing to modern frontend experiences when needed.

In recent years, I have also worked heavily with AI/LLM integration, prompt engineering, and automation workflows, applying these capabilities to real business use cases and internal productivity improvements.

I am open to opportunities where I can combine technical leadership, hands-on development, and product thinking to help teams deliver reliable and impactful software.
