💡 How I work
Every project starts with the business goal and ends with a maintainable, production-ready system:
• define the AI use case and success metrics
• choose the right approach: LLM, RAG, machine learning, classifiers, automation, or hybrid systems
• build a clean pipeline: ingestion → validation → storage → retrieval
• implement guardrails: safety, formatting, validation, fallback logic
• ship with monitoring, iteration, and cost control
🔧 Tech Stack
• AI / LLMs: OpenAI API, Claude Code, Lovable, Cursor, LangGraph, LangChain, embeddings, vector search, RAG, AI agents
• Machine Learning / Data Work: model pipelines, classification, enrichment, data processing, evaluation workflows
• Backend: Node.js, NestJS, Express.js, .NET, Python
• Frontend: React, Next.js, Angular
• Data: PostgreSQL, MySQL, MongoDB
• Automation: n8n, Playwright
• Cloud & DevOps: AWS, Azure, Docker, GitHub Actions
• Product Integrations: Stripe, Supabase, Firebase, Twilio, QuickBooks, Google Maps, Puppeteer, and more
As a Python developer, I use Python for backend systems, data processing, automation, and AI workflows. As a web developer, I build the product layer around the AI so the whole system works smoothly for actual users. And with a data scientist perspective, I pay close attention to data quality, model behavior, and decision logic, because weak inputs create weak AI.
