Engineer first. Founder now. Builder throughout.

A career spent turning complex technology into products, teams and businesses.

01Story

  1. 01

    Software

    I started as a software engineer, and close to two decades later that is still how I think: architecture, backend systems, and the unglamorous work of making software reliable enough that nobody has to think about it.

    That is still the standard I hold everything to.

  2. 02

    From code to systems

    Cloud, distributed architectures, data pipelines, connected devices. The platform I spent the longest on ingests more than ten billion sensor records a day; moving it from file storage to a time-series database took query times from ten seconds to two.

    Somewhere in that progression it became obvious that software is only one component of a product, and rarely the one that fails first.

  3. 03

    From systems to organizations

    When the team was ten people I could hold every dependency in my head. At fifty I could not, and at ninety the habits that had made me useful became the bottleneck: nine managers meant nine interpretations of my priorities, and deadlines rescued by overtime were hiding planning failures.

    Leading engineers turned out to be a systems problem: ownership, interfaces, dependencies, failure modes. I delegate outcomes now and keep the decision. A department I trusted with its own data shrank a 16-terabyte cloud database to one terabyte without me in the room.

    2022

    Until 2022 the team worked from one office in Kherson, ten years side by side. The full-scale invasion scattered it across cities and countries. We went fully remote, relocated people first and kept shipping. Our clients did not notice.

    Roughly a third of the team lost momentum for a while and a third went deeper into their craft; one junior covered senior-level theory in six months. That year taught me more about organizations than any book.

    Industrial technology

    For more than a decade I worked inside industrial operations: sensors on bearings and motors, vibration spectra, predictive maintenance for plants, fleets and warehouses, with systems deployed at Fortune Global 500 companies in logistics, manufacturing and automotive.

    Bearings cause around 40 percent of equipment failures and announce themselves as spikes in a vibration spectrum long before they fail. The analysts who read those spectra were former maintenance engineers working daytime hours in three time zones, and the algorithms, right 90 to 97 percent of the time, still could not replace them. Industry is not my destination. It is where my engineering philosophy was formed, because a factory exposes weak assumptions faster than any code review.

    AI

    AI changed the economics of software: code got cheap, understanding did not. On my teams AI is an analyst, not an executor. Three filters decide what it may touch: blast radius, rollback and real-time visibility. Production access, permissions, payments and over-the-air updates stay human.

    The other half of the problem is people. A fast, convincing answer feels like understanding, so we teach engineers to argue with AI, give juniors problems without an obvious answer, and track cognitive load in our team health checks next to stress and engagement.

  7. 07

    Sivense

    I did not want an outsourcing company. I wanted an engineering company capable of solving technically difficult problems across software, AI, data and connected systems, with the judgment to say what should not be built.

    That is Sivense: incorporated in the US and Europe, 90 engineers across Europe, from Portugal to Ukraine, and a founder who still reads the architecture before anything is committed.

02How I think about technology

  1. 01

    Production is the real test.

    A demo proves possibility. Production proves engineering. A device bricked in the field has no rollback.

    AI is changing DevOps, but production access is still the line
  2. 02

    Engineering judgment compounds.

    Tools change. Judgment remains. A fast, convincing answer feels like understanding, and a muscle you don't train will atrophy.

    The False Expertise Trap
  3. 03

    Organizations are systems too.

    Ownership, interfaces, dependencies and failure modes apply to teams. When a deadline is rescued by overtime, the problem is not the deadline but the planning.

  4. 04

    AI changes the economics of software.

    Code got cheap, understanding did not. Locally correct code that ignores the system is debt, and AI scales bad practice faster than people ever could.

  5. 05

    The physical world is unforgiving.

    Vibration bleeding over from the next machine, a dead sensor battery or a Black Friday load will fool any model that has never been on a plant floor.
