Upwork

Apr 2024 - Jun 2026 • 2 yrs 2 mos

Over the past 2 years, I've worked as an AI Engineer and Software Engineer, designing, building, and deploying end-to-end AI and full stack systems for real production use cases. I've worked across the full pipeline, from data engineering and model development to backend architecture and front-end delivery, rather than owning only one piece of a project. My core focus has been Machine Learning and Agentic AI: I've built classification, recommendation, and fraud detection models, and designed autonomous AI agents that handle multi-step, tool-using workflows rather than simple prompt-response chatbots. I've paired this with Full Stack AI development, integrating trained models and LLM-powered features into working products through clean, well-documented APIs (FastAPI, Flask, .NET). Beyond AI, I've built responsive Web and App experiences, production-grade Desktop Applications in C#/.NET with layered architecture and security best practices, and custom POS Systems for retail and business operations covering transactions and role-based access control. Recent projects include a fraud-detection system combining C# and a Python ML service, a movie recommender optimized 55x for latency, and an NLP news classifier deployed as a live API. Throughout, I've focused on writing clean, maintainable code and shipping systems that actually run in production, not just demos.
