Vadim Sobolev

I'm a self-taught Frontend Developer with a passion for untangling complex codebases—transforming legacy frontend applications into scalable solutions and integrating AI technologies. I also bring backend experience with Express.js and Nest.js, so I can connect frontend architecture to reliable services and data flows.

In my recent role as Team Lead / Frontend Tech Lead at Wildberries, I helped corporate ATS development for HR by replacing a rigid role model with a flexible permission system using the Ability pattern and feature flags. I reduced task estimates from 1–2 weeks to 1–2 days, migrated from flat to feature-based architecture in 2 weeks, achieved a 62% reduction in merge conflicts, and accelerated release timing to save the company around $25,000+—plus I ran a Claude AI prompt-engineering workshop that helped the team hit annual goals 4 months early.
