I work end-to-end: architecture → development → AI integration → deployment, with a strong focus on scalability, clean code, and long-term maintainability. I’ve delivered modern SaaS products, AI-powered tools, admin dashboards, and cross-platform apps for startups and growing businesses.
My core strength is building real AI systems, not just API integrations. I design and deploy LLM pipelines (RAG, vector search, evaluation, tracing) and AI agents that operate reliably in production.
