About
I’m a senior full-stack engineer with 8+ years of experience building and scaling React/Next.js and Node.js (TypeScript) products, from MVPs to production systems. I’ve led teams and delivered real-time APIs, analytics dashboards, and scalable architectures across HR-tech, adtech, and SaaS—often starting from scratch and shaping the technical direction with strong product focus.
I also work on AI-powered features, integrating RAG and MCP-based workflows with multi-model setups via OpenRouter, bringing practical LLM capabilities into production. I enjoy balancing performance, UX, and reliability—whether that’s optimizing load times, building interactive user experiences, or owning infrastructure and delivery pipelines end to end.
