Software Engineer, MSc Thesis Research (ReqSmell) at Blekinge Institute of Technology

January 1, 2025 - Present

Built an AI requirements analysis tool with a live demo, ensuring fault isolation across 4 concurrent LLM pipelines (Claude API, GPT-4) to prevent cross-pipeline contamination. Enforced quality and correctness via CI gates: zero type errors reaching main using mypy strict mode, Ruff linting, and PR gating behind 80% Pytest coverage. Deployed as two independently released services: a React 18/TypeScript SPA and a FastAPI backend, each with independent release cycles.

Built an AI requirements analysis tool with a live demo and evaluated results focused on eliminating cross-pipeline contamination across 4 concurrent LLM analysis pipelines (Claude API and GPT-4). Implemented fault-isolated orchestration using asyncio in a FastAPI backend. Ensured zero type errors reaching main by gating every pull request with 80%+ Pytest coverage, mypy strict mode, and Ruff linting via a GitHub Actions CI/CD pipeline. Delivered as two independently deployed services: a React 18/TypeScript SPA and a FastAPI backend with independent release cycles.
