- FFull Stack DeveloperFlowRMSSep 2025 - Mar 2026 (7 months)As a Full Stack Developer, I architected and maintained a 4-node AI workflow pipeline for automated extraction and normalization of pricing and product data from Excel and PDF catalogs. I redesigned the normalizer system to replace hardcoded per-supplier Python modules with a generic prompt-based approach, enabling onboarding of new supplier catalogs without code changes. Additionally, I implemented a pricing template system that cached the first 3 pipeline nodes, allowing teams to reuse pre-built templates and execute only the final upload node for each new document. I built Celery-based async document execution workflows integrated with PostgreSQL via SQLAlchemy and AWS S3, and implemented streaming-based Excel processing to safely handle

- AI Document Processing PipelineFlow RMSSep 2025 - Current (9 months)As an AI Document Processing Pipeline architect, I designed and implemented a robust 4-node AI pipeline for the automated extraction and normalization of pricing and product data from Excel and PDF catalogs. This involved leveraging streaming-based processing to efficiently handle files exceeding 850MB, utilizing Celery async task queues for optimal performance, and integrating PostgreSQL via SQLAlchemy for effective data management. I also developed AWS S3 file workflows to streamline data storage and retrieval. A key innovation was the redesign of the normalizer system to adopt a prompt-based LLM approach, which facilitated the onboarding of new suppliers without necessitating code changes. Additionally, my work encompassed backend-orient
- Unity Game ProjectsPersonalJan 2025 - Current (1 year 5 months)Built two Unity/C# games: a third-person shooter featuring A pathfinding AI, wave-based enemy spawning, and physics-based projectiles; and a top-down shooter with procedural map generation, multi-level scene management, and event-driven spawn systems.
- Educational Game Development SuitePenguin AcademyJan 2025 - Sep 2025 (9 months)Designed and built two classroom games: a maze game where students program a robot using a custom algorithm interpreter (FastAPI + React/TypeScript), and a web-based escape room with procedural puzzle generation. Both served over LAN with QR access. Also designed and delivered Unity game development courses from scratch and built a Pokémon-style RPG in Ren'Py.
