I lead cross-functional frontend and backend teams through complex product change—from enterprise architecture and API portfolios to customer-facing experiences.

AProfile

For more than nine years, I have worked where business ambition, user workflows, and technical reality meet. I turn competing needs into clear priorities, defined scope, visible risks, and decisions teams can act on.

BProduct practice

From product questions
to useful progress.

My job is not to keep a backlog busy. It is to improve the quality of the next decision and help teams deliver it responsibly.

01

Frame

Use product analytics, research, and stakeholder context to define the problem and make its risks visible.

  • Risk & assumption mapping
02

Shape

Turn the chosen problem into a clear boundary across journeys, capabilities, teams, dependencies, and delivery risk.

  • Wireframes & prototypes
  • Jira Advanced Roadmaps
  • Gantt & dependency maps

Deliver & learn

Make delivery, operations, and feedback visible so teams can release useful slices and adjust from evidence.

Architecture,

Where implementation partners, interfaces, or internal business details are confidential, the case studies focus on my accountability, the product decisions, and the verifiable outcomes.

DExperience

A career built
across the seams.

From application support and business analysis to enterprise Product Owner roles, each step has widened the same perspective: products work when the whole system works.

Small bets,
real systems.

I use independent products to test assumptions end to end—from rules and architecture to the moment a real user can actually interact with the idea.

Live product

Team Next-Level

A released football product that connects card acquisition, collection management, squad construction, competitive modes, objectives, and progression in one operating loop.

LearningA playable system reveals the real product questions: whether value is understood, whether the economy feels fair, and whether one completed match creates intent for another.

Quiz Empire

A live bilingual multiplayer game that combines trivia with territory control, estimation, voting, conquest, and social tension.

FProduct manifesto

Why I build

Validation before velocity.

Technical excellence cannot rescue a product that ignores the workflow it enters. The most expensive product mistake is not imperfect execution; it is confidently solving a problem that does not matter.

AI compresses the cost of learning—from assumption to prototype to user feedback. I use that speed to validate the problem before scaling the solution.

A widely discussed SaaS post described a technically polished healthcare app that consumed $300k and 18 months, yet failed to fit doctors’ workflows.The lesson is simple: validation must happen before commitment becomes expensive.This is my manifesto.

That belief is why I build my own products. A working prototype creates sharper conversations, observable behavior, and better questions than a presentation alone.

GProduct approach

Principles for
useful progress.

  1. 01Validate the problem before scaling the solution.
  2. 02Translate architecture into customer and business value.
  3. 03Make assumptions, ownership, and trade-offs visible.
  4. 04Reduce scope before increasing complexity.
  5. 05Treat delivery as a source of evidence.
  6. 06Use AI to accelerate learning—not replace judgment.

HAbout

My current role.
From platform
to experience.

I work as both a Product Owner and business analyst, taking complex work from the initial brief and discovery through delivery, release, and operation.

My current scope includes end-to-end SEO ownership, refinement of FABRIC (the company's internal FE framework), work with Angular, and full management of the central design system that underpins our shared web components.

I also own cookie consent management and supplier evaluation, frontend logging, and internal product documentation. I use AI to build focused internal tools and automate repetitive workflows, while making technical trade-offs clear enough for stakeholders to decide.

My experience spans telecommunications and iGaming, with additional exposure to banking. I enjoy learning unfamiliar domains and have worked across CRM, frontend and backend delivery, testing, service catalogues, and third-party evaluation.

Outside my professional role, I build products to test my own hypotheses in real environments. Team Next-Level and Quiz Empire are both live. I build them to make my product-validation process more effective.
