Igors Savins — senior full-stack developer

igors@portfolio:~$ cat about.md

Ten years of commercial development. Today: senior developer at a product company — about ten Symfony microservices in production, inside a platform of several hundred services on Kubernetes — and full-stack on my own products, from database to UI.

On the side I take projects: plug into existing systems, read someone else’s code, build integrations, data migrations and automation. Remote, hourly or fixed price per task.

Symfony at work, TypeScript and Next.js in my own products, NestJS, Vue, Go and Python where they earn their place. I pick the stack for the problem, not the other way round.
