I build production-grade web platforms and integrate AI where it drives real business value — from LLM-powered features and autonomous agents to event-driven backends on AWS. Over 15+ years I've delivered full-stack products for startups, SaaS companies and international corporations, most recently on a regulated clinical-trials platform at Sanofi. What I bring to your project: AI product integration, LLM features, chatbots and autonomous agents (OpenAI, Claude, MCP servers), plugged into real business workflows, not demos. End-to-end full-stack delivery : React / Next.js front ends and Node.js (NestJS) back ends, typed end-to-end with TypeScript. Cloud & serverless architecture : AWS (Lambda, DynamoDB, S3, API Gateway), event-driven and idempotent pipelines, infrastructure-as-code. Security & quality in demanding contexts : least-privilege IAM, SSO, automated testing (Playwright, Vitest), CI/CD. A few concrete results: at Sanofi, I built a complete event-driven data-export pipeline on AWS in a regulated clinical environment; I shipped an AI content agent (GPT-4) into a live SaaS platform; and I've modernized legacy stacks to React/Node with measurable gains (−30% UI dev time, −30% deployment time). I also industrialized AI in my own delivery workflow (Claude Code, custom agents), so I ship faster without cutting quality. I take on a small number of projects I'm genuinely qualified for, and I communicate clearly throughout. If you're building something ambitious and want a senior engineer who owns delivery end-to-end, let's talk.
