Solution architecture · Agentic engineering

I architect software solutions, then build and sustain them with AI agents.

I'm Przemek Łuniewski, a solution architect and agentic engineering lead. I work where business meets technology, with one focus: business results, from the first goal to software that stays sustainable for years.

Services

From business goals to results.

I can take a solution through its whole lifecycle, or step in where your team needs help. The work is hands-on, documented and built to be maintained.

  1. Solution and software architecture

    Business goals turned into a solution design your team can build on: SaaS and multi-tenant platforms, integrations, workflows and modernisation.

  2. Agentic engineering

    Software built and maintained with supervised AI agents. Every change carries its plan, acceptance criteria and tests, so speed does not cost quality.

  3. AI enablement and agent governance

    AI agents and LLM features introduced safely: clear rules and permissions, evaluation against ground truth, and review your team can trust.

  4. Secure SDLC and SOC 2

    Security built into delivery, and the engineering groundwork for SOC 2 or ISO 27001.

  5. Engineering leadership

    Technical leadership for your team: standards, architecture reviews, hiring and mentoring.

  6. Organisational change management

    New systems and ways of working, AI included, adopted by your people, not only deployed: stakeholder alignment, clear communication, training and support until the change holds.

How we can work together

  • Fractional role

    Solution Architect or Agentic Engineering Lead, part-time in your team.

  • B2B contract

    A defined scope delivered remotely, with good overlap on US time zones.
