About

Professional summary

I am a Senior Frontend Developer and Full-Stack Engineer with more than five years of experience building scalable, high-performance web applications. I specialize in React.js, Next.js, TypeScript, JavaScript, and Tailwind CSS, with a strong focus on responsive, user-centered interfaces.

I have led frontend engineering efforts for high-traffic products, creating reusable component architectures, design systems, navigation experiences, and data-driven interfaces. I prioritize frontend performance, accessibility, Core Web Vitals, and reliable user workflows.

My full-stack experience includes Node.js, NestJS, Express.js, Python, FastAPI, PostgreSQL, MongoDB, REST APIs, GraphQL, microservices, and real-time applications. I am experienced in designing secure backend services, optimizing APIs, and improving database performance.

I also build practical AI-powered product capabilities using OpenAI, Gemini, Anthropic, RAG pipelines, embeddings, semantic search, tool calling, and ChromaDB. I have applied these technologies to automation, structured data processing, and knowledge discovery workflows.

I am comfortable working in distributed remote teams and partnering directly with clients, product teams, and designers. I bring technical planning, delivery ownership, engineering leadership, and a collaborative approach to solving complex product challenges.
