SH‑07.0 / SUMMARY

Summary

Software engineer with 5 years shipping production React / TypeScript apps and the pipelines behind them. Strong on modern web UI (Next.js, design systems, data‑heavy admin tools) and growing hard into platform work: Docker, CI/CD, Terraform on AWS, cloud hosting, and keeping deploys boring. Comfortable across REST APIs, Node.js, PostgreSQL / relational data, MongoDB, and production debugging — ownership from feature to running system, not just the UI layer.

SH‑07.2 / EXPERIENCE

Experience

Front‑End / Design Engineer

2024 — present

Content platform · Next.js + Payload CMS + MongoDB · pnpm + Turborepo monorepo

  • Ship CMS‑driven UI and platform features — content pages, reviews, layout blocks, FAQ/CTA blocks, search, drafts, live preview, and SEO — in a Next.js + Payload CMS + MongoDB app.
  • Work as a design engineer: designed many production UI blocks and layouts myself — from a rough idea or incomplete Figma to polished, responsive, accessible components adopted into production.
  • Own components end‑to‑end and proactively improve UX, responsiveness, and maintainability, cleaning up legacy code to remove unnecessary complexity.
  • Raised Core Web Vitals / Google PageSpeed on key pages into the 90s (mobile) through image, bundle, and rendering optimizations.
  • Tuned Turborepo caching and the task pipeline to cut incremental build times by ~30%.
  • Introduced and scaled practical AI‑assisted workflows — trained colleagues on LLMs and Figma MCP — and proposed an internal product idea now being advanced inside the company.

Front‑End & Design Developer

2021 — present

Freelance & contract — Next.js, Angular, WordPress, Drupal

  • Built multilingual, multi‑page websites and interactive web apps from scratch — including Vekmed (vekmed.com) and ArtDigital (artdigital.art) on Next.js, plus WordPress and Drupal platforms.
  • Owned UX/UI when clients had no designer or the design didn't match the logic — designed the flows, layouts, and interactions myself and implemented pixel‑perfect, responsive, animated interfaces.
  • Collaborated with designers, SEO specialists, and content teams; integrated Google and third‑party APIs, contact forms, authentication, and payments.
  • Configured hosting and push‑to‑deploy CI/CD (VPS, Nginx, SSL, GitHub Actions) so client sites shipped and stayed live.

DevOps / Platform (Freelance & Personal)

2025 — present

Upwork, Fiverr & personal infrastructure · Terraform · AWS · Docker

  • Designed CI/CD pipelines (GitHub Actions + webhooks) that deploy on push; provisioned and hardened cloud/VPS environments (Nginx, Let's Encrypt, UFW).
  • Used Terraform to define and reproduce AWS infrastructure as code; shipped managed AWS Amplify deploys with branch‑based preview environments.
  • Ran a self‑hosted PaaS (Coolify + Docker) on Hetzner — containers, app deploys, and basic observability (logs, uptime checks, alerts when something dies).
  • Work with PostgreSQL / SQL alongside MongoDB on platform and product work — schema design, queries, and keeping data consistent across environments.
  • Building a Kubernetes cluster with a blue/green rollout pipeline for zero‑downtime releases and instant rollback.
