Application Takeover & Rescue
Your developer is gone. Your application is not. No handover, no documentation, even no repository — we take it from here.
The situation is more common than you think
The freelancer who built your platform stopped answering. The agency rotated its team and nobody remembers your codebase. The technical co-founder left. However it happened, you now run a business on an application that nobody maintains — and every passing month adds risk: no security updates, no backups verified, no one to call when it goes down.
Taking over and rescuing inherited applications is a core Synapse Code service, not a favour we do reluctantly. We have a structured process for it, we do not need the previous developer to be available, and we do not start by blaming their code. The goal is simple: make the system safe, understood and owned again.
No handover needed
We rebuild the picture from whatever exists — even if the only copy of the code lives on the production server.
Stabilise first
Backups, access, monitoring and the riskiest failures come before any feature talk.
No rewrite-by-default
We improve what exists; a rewrite needs evidence, not opinion.
how a takeover works
Secure access
Inventory and secure everything: code, servers, cloud accounts, domains, DNS, databases, third-party services. Recover what is missing. Verify backups actually restore.
Assess & document
The Takeover Assessment: map the code, database, cron jobs, queues and integrations; rank every risk by business impact; write it all down.
Stabilise
Fix the failures waiting to happen — like the production cron jobs we found accumulating until they exhausted server memory. Monitoring, alerting and a deploy process come next.
Own & improve
Move to long-term maintenance: updates, performance work, version upgrades and new features — with one accountable partner.
Unfinished and half-built projects
Sometimes the previous team did not just leave — they left in the middle of something: a migration half done, a rebuild that never replaced the old system, work that exists in a repository but never reached production. We treat an unfinished project like any other takeover: first establish what actually runs in production, then decide with you what to finish, what to roll back and what to drop.
One platform we inherited from a previous vendor came with a half-finished Typo3-to-Laravel migration and a 15 GB repository. We audited it first, then made it safe: backups, security fixes, Docker and around 500 tests.
We work your hours, not just ours
Our engineers are based in Kyiv (EET) and work flexible schedules across an 08:00–20:00 local window. That covers a full UK and European working day. If your application breaks at 09:00 in London or 10:00 in Berlin, someone is already at a desk.
For clients in the US, the time difference works in your favour. Our morning is night across the US Eastern and Central time zones, so fixes and releases go out while your traffic is lowest and your team is offline. We stay on after each release to watch it, with a tested rollback ready. Our afternoon overlaps your morning, so questions still get answered the same day.
takeover questions
No. A handover helps but is not required. We reconstruct the picture from what exists — repositories, servers, databases, DNS, third-party accounts and the running application. Even when there is no repository at all and the only copy of the code is the one on the server, we recover it from there, put it under version control, and document everything we find.
Almost never. Our default is to stabilise and improve what exists. A rewrite is recommended only when the assessment shows the system genuinely cannot be evolved safely — with the evidence to back it up.
Access is granted by you, scoped to what the work needs, and documented — you always know who can touch what, and everything stays under your ownership. NDAs are standard practice on request, and you can revoke access at any time. More on How We Work.
Yes. We audit what exists first: the code, access, infrastructure and how far the work really got. Then we decide with you what to finish, fix or drop. One platform we inherited came with a half-finished Typo3-to-Laravel migration and a 15 GB repository; we made it safe with backups, security fixes, Docker and around 500 tests.
Securing access and removing immediate risks typically starts within the first days. You receive the written risk report early, so you always know where things stand and what comes next.
Whatever access you have: code repository, hosting or cloud account, domain/DNS, database, third-party services. If some of it is missing, recovering access is part of the takeover work.
It starts with a fixed-price Takeover Assessment, agreed up front. Urgent stabilisation is then estimated from the findings and billed for time actually worked, with a budget cap you control — see how pricing works.
You do. Repositories, servers, cloud accounts, domains and third-party services stay under your ownership, and we work inside your accounts. If we ever part ways, you get a clean, documented handover with credentials returned and a transition period for your next team. See our ownership and offboarding promise.

customer testimonials
We engaged them to modernize a legacy internal application, and within months, they delivered a solution that exceeded our requirements on every front. What stood out most was their ability to balance speed with sustainability—they delivered results on a tight timeline without cutting corners. Synapse Code is simply the best external partner we've worked with. We're already mapping out our next development phase.

I worked with Valentyn on a custom web application and it was a great experience. He quickly understood our needs, was deeply involved in the project, and delivered a clear and well-structured solution. Everything went smoothly from start to finish. Highly recommended.
Head of Commercial Operations in Calidad Pascual
We had the pleasure of working with Valentyn Morozov during the implementation of our Electronic Case Report Form (E-CRF) system. From the initial E-CRF setup to troubleshooting technical issues and implementing changes as our requirements evolved, he was always responsive, knowledgeable, and focused on finding the right solution. I highly recommend Valentyn to anyone looking for a knowledgeable, reliable, and committed IT professional.
Country Manager Ukraine at Audubon Bioscience
Working with Valentyn has been a game-changer for us at AUS. We brought him and his team in to transition from our legacy internal app to a new platform, and they exceeded our expectations on every front—delivering in just a few months. Valentyn brings a rare combination of deep technical expertise and strong business acumen. His solutions are smart, practical, and built to last, with a clear focus on quality and sustainability.
Marketing at Advanced Ultrasound Systems
I've worked with Valentyn and the Synapse Code team on transforming an early low-code prototype into a production-ready, multi-tenant SaaS platform. They took ownership of the technical complexity across the backend, frontend, infrastructure, AI workflows, and third-party integrations, replacing a fragile setup with a reliable Symfony, React, and AWS foundation. What I particularly value is that Valentyn approaches the work as a long-term technical partner, not simply as someone completing individual tickets.
