About Hennadii

Your backend shouldn't be the thing that keeps you up at night. My job is to make sure it never is.

I'm a Backend Architect with 12 years designing and scaling the systems behind B2B SaaS products using PHP/Laravel and Python/FastAPI. From first commit to production.

I've launched SaaS platforms from an empty repository, rescued legacy codebases that were quietly strangling delivery, and led engineering teams as a Technical Lead.

I see the whole system, not just my slice of it.
I've shipped production frontends (Angular/TypeScript), so I design APIs the way frontend teams actually want to consume them. And I'm fluent in the DevOps side (Docker, CI/CD, Apache, Nginx), so I architect for how software runs in production, not just how it's written.

I also ran my own dev agency for three years.
So I think about your business outcomes, not just the code, and I'll tell you when there's a smarter way to get there.

How I can help on your mission:
• Backend architecture & clean, well-documented APIs (Laravel, FastAPI);
• New SaaS products designed from scratch, scalable from day one;
• Legacy modernization & tech-debt rescue that gets your team shipping again;
• Performance & scalability tuning so growth never breaks you;
• Technical leadership when you need senior direction, not just hands.

I work best with founders and teams who value good business ethics, clear communication and deliver what was promised.
