Engineer. Collaborator. Maker.
I’m Daniil. I build for the web,
and care about the details.
The short version
Senior Frontend Engineer with 7+ years building high-performance, scalable web applications across React/Next.js and Vue/Nuxt. I'm comfortable owning a product end-to-end - recently the sole engineer behind a full-stack booking platform on Nuxt 4 + Supabase. I focus on performance optimization, clean component architecture, and end-to-end feature delivery, and I'm increasingly AI-augmented in day-to-day work - driving coding agents to ship faster while owning code quality.
Sole engineer on isostudio.pl's booking platform - owned it end-to-end, from the Supabase data model and API to the Nuxt 4 client and admin UI. Shipped the client booking flow (magic-link auth, reschedule/cancel, 4-language i18n) as a PWA, plus a mobile-first admin panel backed by unit-tested API handlers.
Ramped quickly on a large Vue/Nuxt real-time platform, closing 100+ tickets in the first months. Pioneered the team's first technical-documentation system and automated its upkeep with scheduled Claude Code agent routines. Made AI coding agents a core part of my delivery workflow, reaching ~3x feature throughput while owning code quality. Introduced a micro-release process and built A/B testing infrastructure that contributed to measurable revenue uplift.
Built high-performance React/Next.js interfaces across finance, healthcare, telecom, and enterprise projects. Designed scalable, modular client-side architecture and improved application performance by ~50% through component optimization and caching strategies. Developed business modules for a federal telecom operator serving 50M+ users, introduced automated testing reducing manual QA by 500+ hours, and mentored junior and mid-level developers.
Built custom adaptive, cross-browser web apps across multiple products - animation-driven marketing sites plus content-management and online-commerce features for a design agency.
