Vitalii
Kindrakevych.
Senior Full-Stack Engineer with 10+ years of experience shipping production platforms — Drupal & Symfony backends, Next.js / React frontends, semantic search, and AI-integrated tooling. I own projects from architecture to CI/CD.
Senior generalist. Modern stack. End-to-end delivery.
I architect and build production web platforms end-to-end — from PHP backends and React frontends to semantic search, AI-integrated tooling, mobile apps, and DevOps pipelines.
I founded Kindrakevich Digital Agency in Ukraine in 2014 and ran it until 2022, delivering projects across tourism, e-commerce, government, automotive, and B2B marketplaces. Since 2022 I run DevMotion Studio from Cartagena, Spain — partnering with teams who need senior engineering, not task handoffs.
Recent work spans Next.js 16 + Symfony 7 SaaS products, FastAPI services using multilingual-e5 embeddings and Elasticsearch for semantic search, Drupal 11 publishing platforms with custom AI parsers (Claude / OpenAI / Google AI / OpenRouter), apps published on the Shopify App Store, and a React Native / Expo mobile companion to a multilingual travel platform.
My latest product is SettlePay — a crypto-invoicing SaaS that lets freelancers get paid in stablecoins (USDC / USDT / DAI) on low-cost EVM Layer 2 networks (Base · Polygon · Arbitrum · Optimism), with a Symfony 7 backend, React + wagmi / viem / RainbowKit checkout, and a chain listener daemon that marks invoices as paid the moment funds land on-chain.
Five Drupal generations under my belt (7 → 11), two contributed releases published on Drupal.org, and AI-assisted development as a daily practice since 2024.
