/ ALMOST EVERYTHING IS FIXABLE /
Helping you transform your old legacy projects to brand new code - through consulting or hands-on
I'm a fixer. I take the refactors nobody wants to touch — the conversions everyone postpones, the codebases people are afraid of, the upgrades where you're not changing versions but crossing worlds — and I remove the big obstacles so your team has a clear path forward.

Coaching & Well-Being
I turn huge, messy problems into small, doable steps. Analytical but intuitive. I care about code humans can work with — while staying realistic about the business. I deliver from week one: no 6-month planning marathon, I work and document at the same time, which keeps your budget in check. Everything is fixable with the right sequence of moves. It's by walking the path that the path unfolds.
/ WHAT I DO /
- System conversions — MS Access → JavaScript/React, AS400 → modern Java, Java 17 → 21, Spring Boot 2 → 3. Whether you're crossing versions or crossing worlds.
- Cross-functional analysis — talking to end-users, analysts, business to understand what the code should do
- Architecture redesign — Clean Code, Hexagonal, DDD, SOA
- Scary refactors — the ones nobody wants to touch, surfaced and sequenced
- CI/CD setup — Jenkins pipelines, trunk-based dev, Cypress / AssertJ / Mockito test harnesses
- Hibernate upgrades — HBM → annotations, ORM cleanup on millions-of-lines codebases
/ HOW I WORK /
- Incremental, never big-bang — small, safe steps through migration minefields
- TDD and XP by default — test-driven, pairing, mobbing, trunk-based
- Psychological safety first — teams that feel safe ship faster; from my career-coaching background
- Exploratory, not deliverable-driven — I feel around the code and the team, try things, find the right approach — but I always leave a working base + docs
- Fits your team, not the other way around — I adopt the team's conventions, tooling, and taste. If you don't want Lombok, I don't use Lombok
- Agentic engineering — Claude Code, with humans in charge of specs, tests and review
/ WHO I WORK WELL WITH /
- Teams with a system that still runs, but that nobody wants to touch anymore
- Small teams that want someone to make substantial progress in 3-6 months, not just get deliverables
- Teams who want a senior who also mentors juniors, leads tech-debt sessions, and lifts the whole team
- Part-time engagements where I can focus on outcomes, not jumping through hoops
- Comfortable cross-domain — most of my work is in BPM, supply chain, production, government, or coaching
- Founders who need a lean, senior team to build an MVP — my co-founder Matvii and I do this together at Raven Development Studio
/ ALSO A COACH · ENTREPRENEUR /
Moonrebel is my coaching & web-build practice for women entrepreneurs. I help them clarify their brand & vision, then design and build the website with them. 10+ years, 30+ clients.
For a while, I also ran my start-up School of Rebels (2021–2022) - creating a sacred space for online courses for the same people.
