The problem
You have a system that works but gets harder to touch every month. A small change breaks something unrelated, nobody dares open certain files, and the team now takes weeks on what used to take days. You do not need to start over: you need to know which boundaries are missing.
Who it is for
Teams with a product already in production who feel that moving forward costs more every month. If the system does not exist yet, what you need is the end-to-end custom product service.
Why I do not propose a rewrite
Rewriting from scratch is the answer that sounds best and kills the most projects: it freezes the business for months and usually reproduces the same mistakes with newer technology. Phased migration is less exciting to pitch and far safer to execute.
How we work
Diagnosis
I read the code, measure where it hurts, and talk to whoever maintains it. A week of diagnosis avoids months rebuilding on the same problem.
Proposal and scope
What gets modernised, in what order, on what timeline. Including the cost of doing nothing, which is usually the missing argument.
Target architecture
Where the boundaries belong and why. Every decision written down with what it gains and what it gives up.
Phased migration
No total rewrites. Each phase delivers value and can be reverted without dragging the others down.
Handover
Your team keeps documented conventions and automated rules, so the architecture does not erode again a month later.
