What I'm looking for

I’m looking to build reliable, model-agnostic agentic AI in production—owning RAG/multi-agent architecture, evaluation, and observability—while partnering closely with product teams to ship fast, cost-efficient features.

I’m a software engineering student with 2+ years of full-stack experience and a recent deep focus on agentic AI systems. I’ve built and led model-agnostic multi-agent workflows, RAG pipelines, and long-form report generation with evaluation, prompt versioning, tracing, and human-in-the-loop review.

In production-focused work for U.S. clients, I’ve made architecture decisions and provided technical leadership to ship reliable systems. For example, I led a ~20-agent model-agnostic system (research, planning, report editing, and export generation), implemented RAG with PostgreSQL vector search and document ingestion/retrieval, and used prompt middleware, structured outputs, evals, and Langfuse tracing to improve consistency and observability.

I also bring strong full-stack product delivery experience: I redesigned an organizational-climate measurement app using React/Next.js and improved backend features with TypeScript, tRPC, Drizzle, and PostgreSQL. Earlier, I founded and built a hotel management platform from scratch (100+ NestJS REST endpoints, SSE flows, Playwright scraping, JWT auth, PostgreSQL modeling, and Jest TDD) while leading a team at a regional hackathon and mentoring students through software engineering tutoring.
