For 14 years I build systems that survive contact with reality.

Łukasz Adamczyk · Frontend Technical Lead · Solution Architect · Senior Engineer

Open to work

Observations

I don't write legacy code. I write code that becomes legacy.

14 years of JavaScript

Defined the DoD, DoR, and Jira workflow. The team had opinions. We reached consensus. I was right.

HSBC · Team standards & process

Rewrote it before release. Called it 'simplification'. Everyone agreed.

HSBC · Application audit & rewrite

Delivered internationally. The timezone was never the biggest problem.

International delivery · UK, SG, DE, SE, IS, PL

Zero config. One dependency. Infinite excuses removed.

QoQ · Code quality orchestrator

Fixed a bug that had been silently failing across multiple projects for nine months. Filed under "quick win".

HSBC · Bank-wide component library

1:1s, performance reviews, mandatory PR reviewer. Technically a lead. Practically, the last line of defence.

Sartorius / Bayer · Team Lead

The thermostat integration works. My house is now a YAML file.

salus-it500 · Home Assistant

Gave a talk on avoiding human errors. Pushed a typo to the slides the morning of.

Meet.js Łódź 2024

Designed the system, decomposed the requirements, led the team. Turns out that's still one person.
