Dmitry
Mikhailov

React, Next.js and TypeScript developer for website fixes, responsive interfaces and API integrations. Commercial work includes frontend delivery for independent clients and multilingual content projects. I reproduce the issue, agree on the scope and acceptance criteria, implement a focused change in Git, verify the result and provide a short handover. Own examples: Voxel Drop (React/Three.js interactive UI) and Async URL Checker (NestJS/React technical assignment with tests and documented limits). These are portfolio projects, not client case studies. Available for remote fixed-price tasks and paid pilots; written communication preferred. Based in Kemerovo, Russia, self-employed contractor. Code and demos: github.com/fsaidad. Education: TUSUR, Radioelectronic Systems and Complexes, 2022-2025; incomplete higher education.

Work experience

Independent projects

August 2023 – April 2026

Job title

Frontend Engineer

Work experience & achievements

Commercial frontend work for independent clients: React/Next.js interfaces, TypeScript components, REST integrations, responsive layouts from Figma, client state and Jest/Vitest tests. Used React DevTools profiling and other debugging tools on a UI with 1,000+ items; reduced unnecessary re-renders by about 85% in the measured scenario. Coordinated frontend integrations in a five-developer team that delivered a working prototype in one month.

Commercial project (NDA)

January 2026 – July 2026

Job title

Frontend Developer

Work experience & achievements

Frontend and content delivery for two commercial multilingual projects under NDA: about 5,000 generated pages in 10+ locales. Built a JavaScript/Markdown pipeline and validation of more than one million internal links per run. Worked with Hugo, REST APIs, hreflang, sitemaps and redirects. Key tested templates reached Lighthouse scores of 95-100 in mobile mode. January-July 2026.

Archived independent project. Public hosted demo is currently unavailable; review the source instead. Next.js, React, TypeScript, PostgreSQL, validation, server-sent events and tests.

Horizon Walk — atmospheric 3D exploration

My own atmospheric browser game, built with TypeScript and Three.js/WebGL2. Procedural landscapes, first-person movement and collisions, weather and fog, reproducible worlds by code, graphics settings, photo mode and a pocket with discoveries saved across worlds. A repeatable route and frame-time reports help investigate performance on a stated device and configuration. The attached image is an actual in-game photo.
