Kliś
Most startups struggle to ship fast without accumulating technical debt. I help product teams build reliable software with speed and craft — from hands-on coding to technical leadership.
Move fast.
Build right.
Scaling teams, chaotic roadmaps, technical debt piling up — been there. With 15+ years across SaaS, fintech, and e-commerce, my job is helping product teams ship fast without the shortcuts that cost you later. Bridging product goals and engineering execution.

How I Help
Services
Product Development
Your team is at capacity but the roadmap won't wait. I embed with your team to ship features fast — clean code, tight feedback loops, no shortcuts.
Technical Strategy & Architecture
Wrong technical decisions cost months. I help you choose the right architecture, stack, and patterns — so technology accelerates your business.
Team Leadership & Augmentation
Missing senior engineering leadership? I ship production code and lead architecture decisions — raising the bar for the whole team.
Technology
Tools I enjoy shipping with
These are the tools I reach for most — but the stack is always chosen for your product, not my resume. I adapt to what your team and codebase need.
Process
From idea to reliable software
A repeatable approach that keeps scope tight and momentum high.
Step 1
Understand
We start with a focused discovery call to align on what matters most — your goals, constraints, and timeline.
Step 2
Plan
I trace a pragmatic path with measurable milestones. No over-engineering, no guesswork — just a clear plan you can trust.
Step 3
Build
I ship high-leverage work in tight feedback loops. You see progress every week, not after months of silence.
Step 4
Deliver
Clean handover, monitoring, and production support. Your team owns the code and can maintain it long after I leave.

Shipping code and leading architecture decisions — you get both.
Design-sensitive engineer

Product thinker, not a ticket executor
Understanding why features matter, not just how to implement them.
Community builder
CSSconf EU organizer, JSConf EU volunteer, Rails Girls coach.
Battle-tested in scale-up chaos
Wimdu, rebuy, Coya, Surfer. No panic — just shipping.

Every month without the right engineering partner is another month of accumulated debt and delayed launches. You bring the product vision — I bring the craft to make it real.
