Building resilient SaaS platforms, autonomous AI agent architectures, and high-performance web applications.
What began as a curiosity-driven journey has evolved into a relentless focus on solving complex, real-world problems through robust software engineering and applied AI.
I specialize in bridging the gap between autonomous AI systems and scalable cloud-native web architectures:
- 🧠 GenAI & Agentic Workflows: Architecting agentic systems, RAG pipelines, voice interfaces, tool calling, and usage metering for AI workloads.
- ⚙️ Distributed Backend Systems: Engineering high-reliability backends with FastAPI, Node.js/Express, Celery, PostgreSQL, and Redis, emphasizing idempotency, zero-downtime migrations, and exact business constraints.
- 🎨 Modern Frontend Engineering: Crafting fluid, accessible user experiences using React 19, Next.js 15, TypeScript, Tailwind CSS v4, and shadcn/ui.
- 🚀 End-to-End Ownership: Comfortable driving projects from architecture design and database modeling to deployment and automated monitoring.
Note
