Full‑stack software engineer specializing in AI/LLM integrations, building web apps with scalable backends and modern frontends.
I am a full‑stack software engineer with hands‑on experience integrating generative AI, RAG pipelines, and vector databases into production web applications. I have built end‑to‑end systems—APIs with FastAPI, responsive frontends with Next.js/Svelte, and AI features using OpenAI and Google Gemini—focused on usability and secure authentication.
My work includes developing HR automation bots, an AI tutoring platform, and appointment/booking systems that leverage Google OAuth, real‑time WebSockets, and multiple third‑party calendar integrations. I prioritize maintainable code, SOLID principles, and delivering measurable product improvements through AI and modern web technologies.
