Subject profile // 01
Product Engineer — product, architecture, delivery.
I own outcomes end to end — from the business reason to the shipped product. Architecture, delivery and the product itself, in one pair of hands.
Profile // 02
I'm a product engineer who owns outcomes end to end — from business reasoning and discovery through architecture, implementation and delivery. I care about the product itself, not just the code: I feel ownership of what we build and help shape how customers' products evolve.
Strong on clean, maintainable architecture (DDD, hexagonal), with deep React and TypeScript roots and a solid Linux and cloud foundation.

Jun 2010 – Oct 2011
Eastern European Sales Team SA
Administered Linux servers and Windows terminals, maintained Asterisk servers, delivered and integrated open-source CRM, and handled MySQL/PostgreSQL database administration.
Mar 2011 – Dec 2015
Hentel Henryk Zajma
Designed and led software for telecom-device monitoring and CRM/ERP integration (MeteorJS, AngularJS, MongoDB, Django). Asterisk PBX configuration and Linux administration.
Jan 2016 – Mar 2018
Nokia
Built a complex in-browser application for BTS Operations & Management — communicating with telecom hardware over a dedicated protocol, presenting live device state and issuing operations.
Mar 2018 – Aug 2021
Nokia
Designed and developed web apps (Node.js, Django, TypeScript, React), provided technical support to the team, built PoC projects to start new initiatives, and promoted clean code across teams.
Sep 2021 – Aug 2024
Techtailor
Built frontends for business web applications and owned production build/dev tooling. Optimized rendering, bundle size and load time, configured CI on GitLab, drove code quality and architecture, and interviewed engineers.
Aug 2024 – Present
Livespace
Product engineering across the stack — taking features from business reasoning and discovery through planning, frontend implementation (React, Next.js, TypeScript) and deployment. Operating between product and engineering rather than building UI alone.
Capabilities // 04
Six clusters, one engineer. Point at a cluster to light it up in the projection.
Missions // 05
Selected work, declassified: the problem as it arrived, what changed, what it ran on.
Problem
Sales teams were slowed by complex, fragmented workflows and a UI that didn't keep up with how deals actually move.
Outcome
Reframed features from the business goal down, then delivered them end to end — streamlining the day-to-day flow and shortening the path from idea to shipped feature.
Stack
Problem
Heavy business apps suffered from slow rendering, large bundles and inconsistent front-end architecture across the codebase.
Outcome
Owned front-end architecture and CI, profiled and removed rendering bottlenecks, and trimmed the bundle to cut load time noticeably.
Stack
Problem
Operators needed to drive telecom base-station hardware and read live device state directly from the browser, over a dedicated protocol.
Outcome
Delivered a reliable in-browser console that presents live hardware state and issues operations safely against real devices.
Stack
Problem
A new internal initiative needed evidence of feasibility and a clear product direction before larger investment.
Outcome
Built a focused PoC that proved the concept and shaped the direction, de-risking the decision to invest further.
Stack
Problem
Telecom devices, CRM/ERP systems and telephony lived in silos, with manual work bridging the gaps.
Outcome
Connected device monitoring with CRM/ERP and automated the Asterisk PBX on a solid Linux foundation — removing manual handoffs.

Operating mode // 06
I build with AI agents, custom skills, MCP and orchestrated workflows — shipping production-grade products faster, without trading away quality.
We start from the business goal, not the ticket. I dig into the problem, the users and the constraints, then frame what's actually worth building.
I shape a clean, maintainable design (DDD, hexagonal) and a delivery plan with clear milestones — so scope and trade-offs are explicit up front.
Production-grade implementation in React, TypeScript and Next.js — built with AI-assisted velocity, tested and reviewed, shipped in small increments.
Deployment, hosting and CI/CD are part of the deal. We ship, watch how it performs, and iterate on what the product actually needs next.

Full-cycle product delivery billed per full month: business reasoning and discovery, planning and architecture, implementation, deployment and hosting. Minimum one month, with one fixed all-in rate.
Yes — I work fully remotely and have collaborated with teams across Europe and Scandinavia. I'm based in Poland (CET) and keep solid overlap with most European and many US-East working hours.
You do. Everything I build for the engagement — code, architecture and assets — is yours. I work in your repositories and follow your review and security practices.
One fixed all-in monthly rate, billed per full month, with no hidden extras. Discovery, planning, implementation, deployment and hosting for the project are all included.
Absolutely. I'm comfortable owning a slice end to end or plugging into an existing team — improving architecture, performance and delivery without disrupting how you already work.
