I take on complex UI systems and leave them easier to change.
(01)Philosophy
The world as we have created it is a process of our thinking. It cannot be changed without changing our thinking.
— Albert Einstein
I build frontend systems for products that cannot assume ideal conditions — from industrial machines and offline retail tools to healthcare and worldwide people systems.
My work makes long-lived products easier to change, faster to use and safer for teams to own. Architecture matters when it improves the next decision, not when it adds ceremony.
I stay hands-on, explain trade-offs and leave behind patterns that teams can continue without me.
(02)Impact, in numbers
(03)Expertise
Built for real constraints.
Capability
Systems That Stay Changeable
Architecture, state, routing and contracts designed to reduce the cost and risk of changing long-lived products.
→ Angular modernization · React and Kotlin orchestration · typed binary-to-UI contracts.
Capability
Performance Under Real Constraints
Measured improvements across stream-heavy products, hardware-integrated interfaces and offline workflows.
→ Reported +45% rendering speed · +25% state-store throughput.
Capability
Reliability Beyond the Happy Path
Frontend engineering for varied hardware, unreliable networks, global locales and privacy-sensitive data.
→ Reported scope: 35,000 machine configurations · 300+ stores.
Capability
Technical Direction Teams Can Use
Hands-on leadership that turns decisions into understandable patterns and leaves teams able to continue.
→ Direction during a leadership gap · mentoring · team growth from 4 to 14.
(04)How I contribute
Leverage across teams and systems.
Hands-on architecture, measurable performance work and technical direction for teams responsible for complex, long-lived products.
UI architecture audit
A focused review of boundaries, state, routing, rendering, accessibility and delivery risks in a complex front-end.
- Prioritized architecture findings
- Modernization sequence with trade-offs
- Concrete performance and maintainability actions
Angular modernization
Hands-on modernization that improves architecture and performance without stopping product delivery.
- Incremental migration plan
- Signals and RxJS boundaries that remain understandable
- Measured rendering and bundle improvements
Technical delivery leadership
Short-term senior technical leadership for difficult product phases, from discovery through a stable handover.
- Clear technical direction
- Decision records and reusable patterns
- Coaching that leaves the team stronger

Workday
Software Engineer · 2022 — Now
People Analytics, localized and embeddable.
- Built the i18n system for the People Analytics dashboard.
- Wrote a migration script, before AI-assisted tooling, that moved legacy logic into the new model format.
- Created an embed scheme so Workday bespoke apps could be used as business-strategy and AI-ready components.
- Set routing architecture and data flow so those bespoke applications stayed predictable.

(06)Kind words
Said by the people I build with.
Tom is one of the most creative and fast adapting colleagues I had the luck working with. From discussing architectural concepts and choices to implementation, he is capable to easily keep up with changing requirements and specifications in his design, while still having enough foresight to put an optimization here and process convenience there.

(07)About
Irish. In Prague.
I’m an Irish UI systems architect and Angular consultant living in Prague with my wife and three kids. A BSc (Hons) in Business & Computing gave me the dual lens I still use today: technical decisions must improve both the system and the outcome it exists to support.
