Travel assistance e-commerce, multi-country and multi-gateway, in production since 2023.
What holds a product up is almost never the part you see.
I work where it gets hard: fragile integrations, inherited code, decisions with no obvious answer.
I build with AI agents now. The tool changes; the judgement stays mine.
Spec-driven development: first the problem, the architecture and what will count as done; then the implementation, split into small units that get verified one at a time. Agents run inside that frame, on gentle-ai, the ecosystem by Gentleman Programming. Not to go faster — to cover more ground without lowering the bar.
See gentle-ai ↗Before any spec the idea is argued and defended: what it solves, for whom, under what constraints, with what architecture and at what cost. That argument produces a written concept, not a hunch.
The first spec is never treated as final. The process hands back what was not considered: gaps, contradictions, edge cases, pending calls. Only once those are settled does the proposal come out, and everything else grows from it.
The plan is cut into modules, and each module into small, verifiable slices. Not bureaucracy: it is being able to say at any moment what is done and what is left, in a kind of work where losing the thread is easy.
None gets improvised: contracts, dependencies, edge cases and what will count as done are set before execution starts. Agents run inside those limits, and they are not the ones who set them.
Nothing is accepted because it looks right: every slice has to meet its criteria, pass its tests and survive a review. If it does not pass, it does not matter who wrote it.
The tool executes. The decisions are not delegated.

Frontend Developer
I led the architecture and development of the travel assistance e-commerce, and single-handedly migrated another critical e-commerce from Angular 11 to Angular 18. Also ordering systems for self-service kiosks used by global brands, and a modular dynamic PDF catalog generator with price inheritance across stores.
