Akmé — Triathlon tracking web app (personal product)

Triathletes generate a huge amount of data: times, routes, nutrition, results and personal records. That information usually lives scattered across apps, spreadsheets, photos and notes, making it hard to see the full picture of athletic progress.

Existing tools solve individual needs — tracking workouts, analyzing routes, calculating pace — but none bring the complete triathlon experience together. Athletes end up rebuilding their history by hand and losing the context behind each race.

I led the project end-to-end, from defining the problem to designing and building the functional product: product strategy, UX/UI design, information architecture, feature definition, front-end development, backend integration, and testing with iterative validation. As a triathlete myself, my domain knowledge helped turn real needs into product decisions.

A specialized platform that brings training tracking, race history and performance analysis together. The first version has six core modules:

Performance evolution and metrics

Personal records

Race history

Cumulative route map

Nutrition by race stage

Predictive time calculator

Each one answers a question athletes ask after training or racing: How am I progressing? What did I learn from this race? How far did I actually go? What do I need to reach my next goal?

With an AI-assisted Product Engineering approach — not just to write code faster, but to shorten the cycle between idea, implementation and validation: Problem → Design → Implementation → Testing → Iteration Claude Code was the primary development tool, while product, UX and architecture decisions were defined and validated throughout.

Akmé validated a product development approach: turning a product hypothesis into a functional product within weeks, reducing the cost of validation before larger investments. Development speed depends less on the stack and more on how clearly the problem is defined.

AI accelerates implementation, but it doesn't replace product judgment. Identifying a meaningful problem, defining a coherent solution and validating each decision is still the real differentiator.
