NetherlandsWhat I'm looking for
I've built and modernized web applications for Hoodies, PlantVillage, Onlinetours.ru, and WB—Tech, working across startups and established products in distributed teams.
At Hoodies, I reduced mobile page load time by 13.2%, enabled real-time delivery tracking that cut support requests by 23%, and built MVPs to validate ideas and support early-stage funding. I also resolved rendering and animation performance issues on mid-range devices.
At PlantVillage, I built a crisis-response MVP in one week during the 2020 locust outbreak, replacing a legacy map with a 3–4 second load experience for a platform supporting a UN FAO-led response across East Africa. I later introduced a new frontend stack and design system that sped up development by 34% and overhauled the public site to improve load time by 42%.
I enjoy owning features end-to-end, from requirements and UI/UX collaboration through implementation, testing, and iteration based on user feedback and analytics. I'm currently exploring how AI can enhance my work as a frontend developer.
