Leonardo Lessa

Frontend Developer

About

I'm a frontend engineer with 10+ years of experience building, evolving, and sustaining digital products. I like to be deeply embedded in every project: understanding the domain, shaping business discussions, anticipating technical risks, and being the person who knows how all the moving parts fit together.

Early on I spent almost two years in the DWS (Deutsche Asset & Wealth Management) ecosystem applying Atomic Design to build template and component systems. Later at Senior I dove into the ERP world and became the frontend reference on the finance team, owning critical modules and code standards.

At HOX I took on the challenge of re-architecting and restructuring the Dynapredict (Dynamox) frontend, maintaining and evolving its foundation over three years. In parallel, I led and delivered high-impact campaign experiences for brands like Netflix, Spotify, O Boticário, Vivo, and SporTV—balancing performance, timing, and feasibility.

More recently I've architected products such as FORE, WePRO, Valana, and Mappo. I act as a bridge between technology and strategy, weighing trade-offs clearly and guiding decisions that enable sustainable growth, maintainability, and real business impact. What drives me is turning ambitious goals into consistent, scalable, and elegant solutions.
