# what people come with

[FAIL]the site stopped working, started throwing errors, or broke after an update
[FAIL]the previous programmer is unreachable and there is nobody to maintain the project
[FAIL]the site and the CRM, warehouse, accounting or payments do not exchange data
[FAIL]slow loading, crashes under load, database trouble
[FAIL]search rankings dropped after a move or an update
[WARN]data is carried between systems by hand and needs automating
[WARN]legacy nobody dares touch — rewritten piece by piece, not all at once
[WARN]moving a site or a product catalog to another platform
[INFO]new features in an existing site or accounting system
[INFO]plugins and modules for a specific CMS
[INFO]parsers: collecting data from other sites and from exports
[INFO]integrations with external APIs and services
[INFO]a new project from scratch — from the data model to launch

Legacy is a normal working situation, not a reason to rewrite everything from scratch: old code, someone else’s code, no documentation, no previous developer. I work it out from the code itself.

A job starts with a written brief: what exactly gets built, in what scope, on what deadline. Once both sides are looking at the same picture, development begins — no guessing, no surprise invoices.

igors@portfolio:~$ cat about.md

Ten years of commercial development. Today: senior developer at a product company — about twenty Symfony services in production, ten of them mine as lead developer. The platform runs several hundred services on Kubernetes. On my own products I am full-stack, 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 around.

# certificates

Courses and training, not vendor certificates. They show what I have been learning lately, nothing more.
