You're stuck in legacy code — slow delivery, constant bugs, and nothing your team has tried has fixed it. Adding AI on top only made delivery worse. You're the one who wants to drive the change — you care about getting it right; what's missing isn't the will, it's the how. And that's exactly what Optivem Circle gives you — working through the real problems you're facing, alongside other engineers doing the same.
Working in legacy code is relentless pressure — stressful deliveries, slipping deadlines, and fresh bugs every time you touch code no one fully understands.
Every change to the legacy core feels like defusing a bomb — no tests, no safety net, no fast feedback. So you lose hours to manual checking, and shipping brings dread instead of relief. The business wants things faster; the code gives you slipping deadlines and fresh bugs every time you touch it.
Textbook examples are clean. Your production codebase is not — and the gaps are everywhere, each one specific to your situation in ways no book covers. You've even tried things yourself, and watched a half-applied refactor or a brittle new test suite leave it worse than before — and your colleagues, watching it fail, walked away convinced the whole approach just "doesn't work."
It generates code that semi-works — plausible, not correct. AI sped up writing code, but writing was never the bottleneck; testing was. So it just ships the wrong code faster, and you've become the human regression suite: seniority spent reviewing a firehose of AI PRs juniors can't defend.
And the code it generates isn't built to be maintained, with no one on the team really understanding it — so the only way to change it is to hand it back to the AI. Every pass burns more tokens, and your grip on your own system slips further. You're not building capability; you're building dependence.
Plausible-but-wrong code piles up faster than anyone understands it — but "AI writes the code now" has become the reason to stop worrying about tests and design. Pushing for quality reads as slow and old-fashioned, and the people you'd have rallied are the ones cheering the speed. You're the only one who seems to see it.
And you're the one trying to change it. But wanting it was never the hard part — knowing how to make it stick is.
Imagine six months from now:
No curriculum. No slides. Q&A on what you're actually working on — live on the calls and async between them. Advisory support for engineers already doing the work.
A 2-hour live session every two weeks. Bring the real challenges from your work — queue your questions ahead and they're scheduled to be talked through at the next session, or raise them live. It's a real discussion about your situation, not generic advice — we work through your specific case together. Code examples where available.
Hit a wall the day after a call? Post it async and get it answered in the open — and every answer compounds into a library you can search.
Both the live calls and the async threads run in the open — so proprietary code stays off them. That's what Teams is for.
Some of what you're hitting, you've solved before. Some of it you haven't — and that's the point. Bring the real problem, talk through the approaches with someone who's worked them, and leave with a recommendation you can act on. We go as deep as the question needs — no rushing to move on for the sake of it — and if a follow-up comes up after the session, that gets worked through too: pick it back up on the next call, or async in between.
That's what Optivem Circle is for.
Optivem Circle is built first for senior engineers and tech leads hands-on in a legacy codebase and pushing to make it better. But the same problems land on a wider set of roles — and whatever your title, if you're driving legacy modernization, you're who this is for:
And really — anyone serious about modernizing legacy code.
There's no curriculum — you bring what's blocking you. A course fixes its scope up front, but legacy code never respects a syllabus; here the scope is unlimited, so whatever's actually blocking you is on the table — including the big stuff like architecture, refactoring, and legacy modernization. A few examples of the kind of thing:

A standing line to senior guidance on the legacy code you're up against.
Save 20% · about €77.50/mo, billed yearly
Join AnnualEverything in the membership, on the shared public calls — put your whole team on one invoice and expense it once, instead of each engineer signing up and claiming it back. A volume discount grows with headcount.
On top of the annual per-seat price
All plans billed in advance · cancel anytime — access continues to the end of the period you've paid for. Plus a 30-day money-back guarantee: not 100% satisfied in your first month? Full refund, no questions asked.
Whether it's a single seat or a whole team's invoice, this can be a work expense rather than an out-of-pocket cost — an invoice (company name + VAT) is available on request to claim from an L&D / training budget. Here's a ready-to-send manager email and the invoice details →
That's Optivem Teams: dedicated sessions reserved for your engineers alone, on your real, proprietary code, in full confidence. The one option that works on your code, not open-source examples.
Technical Coach at Optivem. Years spent helping engineering teams modernize legacy systems without years of expensive trial and error.
"Teams aren't stuck for lack of theory. They're stuck because no one's shown them how to apply it to real, legacy code."
Creator of the ATDD Accelerator, putting Agentic AI to work inside the loop to ship changes to legacy code more safely and faster. Optivem Circle brings that same guidance to any engineer fighting through it.
Practical, live guidance for the legacy code you're up against — every two weeks.
