I'm Pierre-Henry, a software engineer who enjoys building products, solving difficult problems and learning by doing.

I've worked on everything from mobile apps and healthcare platforms to large-scale integrations and open-source software. I care about the details: readable code, reliable systems, good tests and understanding why we're building something before deciding how.

Outside client work, I build my own projects, share what I learn and keep experimenting with new ideas.

✅ Own the outcome, not only the code. I work from problem definition and trade-offs through architecture, implementation and production operation.

✅ Treat correctness as a product requirement. Testing, review, reliability and clear failure modes matter when software supports consequential decisions and real operations.

✅ Prefer clear, maintainable systems. I value simple boundaries, explicit decisions, readable code and solutions that fit the problem.

✅ Use AI with engineering discipline. Agents, MCP tools and reusable skills increase delivery speed, but their output still goes through design, testing and review.

✅ Learn by building. A programming language, a long-running open-source platform and ongoing AI and data work reflect how I deepen technical understanding.

✅ Commit for the long term. More than 11,000 open-source commits and products carried from idea to production show the value I place on follow-through.

✅ Share what I learn. Open source, four software-engineering courses with more than 225,000 combined enrolments, videos and writing are part of my engineering practice.

✅ Take care of the people around the work. I value honest communication, useful documentation, teaching and constructive technical review.

✅ Stay curious. Learning, researching and testing ideas in practice remain part of my daily routine.
