Jan is now available for hire Hire Jan

I'm a senior Symfony and PHP developer with 12 years of production experience and about 9,000 commits across 29 active repositories. I build and run complex web platforms end to end - from Doctrine data models and Symfony back ends to Vue.js front ends, payments and deployment.

What I build with Symfony

Marketplaces and SaaS platforms on Symfony 7 and PHP 8
Complex Doctrine data models, migrations and data import pipelines
Payments and billing with Stripe (webhooks, SEPA direct debit, payouts, invoicing)
Integrations: HubSpot, Google APIs, OpenAI, Amazon Product Advertising API
Symfony upgrades and modernisation with Rector, PHPUnit and PHPStan

Selected projects

Hiremotely / EliteBrains (2019 - present): lead developer of a Symfony 7 + Vue 3 marketplace with ATS, skills testing, contracting, timesheets, invoicing and Stripe payments. Led a team of 6-8 contributors and authored about 3,000 commits.
Imaging Resource (2014 - 2022): Symfony back end and front end of a large US camera and lens review site - specification database, A-vs-B comparison engine, affiliate pricing and ad stack. Sole developer from 2017, about 3,700 commits.
Monitoring SaaS (2026): multi-tenant uptime, SEO and log monitoring on Symfony 7, FrankenPHP and Docker, with Messenger, Mercure and SMS/webhook alerting.
Sandoz / Hexal (2020 - 2024): interactive pharma sales presentations in Vue.js and JavaScript for Veeva CLM and Pitcher.

How I work

I deliver in clear, documented phases with tests from day one (PHPUnit, Vitest, Playwright). Since 2026 I use AI coding agents in a spec-first workflow, which lets me ship much faster without losing control over quality. I also build Flutter mobile apps and Python services with FastAPI.

I work remotely from Prague and communicate in English and Czech.
