Suman Raj Bista

I’m a Full-Stack Software Engineer with 3 years of experience building scalable web applications using FastAPI, Next.js, and ASP.NET. I bring strong hands-on skills in Python, TypeScript, and PostgreSQL, with real-world experience integrating AI models (LLM, RAG, Ollama) into enterprise systems.

In my current role as a Software Developer at K. System Pvt. Ltd (YLW Softlab, S.Korea), I help deliver an AI-powered chatbot using FastAPI and Svelte5, including RAG, multi-tenant architecture, and LLM model orchestration. I optimized backend logic and database queries, reducing API response times by 40%, and designed automated testing frameworks with Cypress (E2E) and Vitest (Unit), improving test coverage by 60% and cutting manual QA effort by 80%.

I also build tools that move fast from idea to production—like a scalable ETL tool with ASP.NET Core that achieved 30% faster processing, and deployment improvements that increased efficiency by 60% through documentation and streamlined code handovers. I’m comfortable working cross-functionally in Agile/Scrum environments, and I continuously focus on performance, reliability, and maintainable delivery.
