About

Engineering decisions with business outcomes in mind.

I'm a software engineer with 10+ years building and evolving digital products across e-commerce, logistics and renewable energy.

I help startups and growing businesses turn early traction into scalable products, whether that means building an MVP, modernizing an existing platform, improving performance, or bringing structure to a growing technical operation.

Beyond pure engineering, I contribute to product direction, technical strategy, and business decisions that directly impact growth and revenue. My role is often to bridge the gap between business goals and technical execution.

I specialize in pragmatic architectures: solving real problems with the right level of complexity. Not more, not less.

Philosophy
Don't overengineer too early. Deliver reliable, efficient solutions aligned with the business stage. Validate, grow revenue, then evolve toward greater scalability, when it truly matters.
What I do

Three ways I plug in.

01

From MVP to product-market fit

Designing and building MVPs with the right level of simplicity and structure to validate ideas quickly and support early growth.

Who I help

If any of these sound familiar, we should talk.

01

Startups with early traction

Companies with a product in market that need to scale revenue and growth through better technology.

02

Non-technical founders

Founders who need a trusted partner to turn ideas into structured MVPs and make the right calls from day one.

03

Tech–business misalignment

Companies where technology has drifted from business goals and need clear direction, prioritization, and execution.

04

Teams facing instability

Products suffering from recurring production issues, poor performance, or technical debt that limits growth.

05

Outgrowing current systems

Businesses that started with quick or improvised solutions and now need to evolve their platform.

06

Founders without a CTO

Companies that need fractional C-level technical leadership without committing to a full-time hire yet.
