About me
I build production-grade apps — not prototypes. Full-stack developer specializing in AI-powered SaaS, automated data pipelines, and mobile/web apps built to scale.
I've shipped two solo platforms: a subscription SaaS (web + Android) with Stripe billing, 6 live APIs, and an AI assistant — and a 7-microservice automation platform with a 3-agent AI system and live React dashboard.
What I build: SaaS MVPs · React/Next.js dashboards · FastAPI backends · React Native apps · Multi-agent AI · Data pipelines · Stripe subscriptions

Debugged and fixed logic, runtime, and deployment issues in existing Python applications. Identified root causes of crashes, incorrect outputs, and performance problems. Worked with existing codebases (not greenfield builds), including web applications and data-driven scripts. Improved application stability, correctness, and usability by correcting flawed logic and broken functionality.
