Marcin Ciesielski

About me

→ I build fast and reliable MVPs for startups – delivering a fully functional application prototype within just a few weeks.

→ With many years of experience in software engineering and hands-on work as a cybersecurity expert (NIS2, DORA, ISO, SOC 2, pentesting, threat modeling), I create solutions that are resilient, secure, and ready to scale from day one. I have extensive experience building complete systems end-to-end: backend, APIs, integrations, business logic, architecture, automation, and application security.

→ If you need a rapid MVP ready to present to investors — I will build it for you in a professional, secure, and cost-effective way.
