About

Solutions Architect and Technical & Business Analyst with over 12 years of engineering experience. I talk directly to clients and stakeholders, and beyond defining architecture and technical details I get involved in product-level discussions, evaluate features and propose better solutions that improve the final product.

I act as a team multiplier: improving team efficiency, sharing knowledge and removing technical blockers. I define target architectures, build roadmaps and set engineering standards through C4 modelling and Architecture Decision Records, apply Domain-Driven Design concepts and architectural patterns to build scalable systems, and work closely with Product and Engineering Managers so technical decisions stay aligned with business goals.

  • Architecture & strategy

    Target-state definitions, roadmaps, C4 models and ADRs. Microservices, CQRS and modular monoliths, chosen to fit the problem.

  • Analysis & alignment

    Requirements gathering, vendor and build-vs-buy evaluation, and a direct line between customers, product owners and engineers.

  • Hands-on engineering

    Core platform code in Node.js and .NET, API design, integration patterns, code reviews and mentoring across the team.
