PHP Application Maintenance

Support for the PHP system your business runs on — whoever built it, however old it is.

“It works, but nobody dares touch it” — we fix that

Thousands of businesses run on custom PHP applications written five, ten, fifteen years ago. The systems still work — orders come in, reports go out — but the people who built them are gone, the PHP version is out of support, and every change feels like defusing a bomb. Meanwhile the business keeps asking for "one small change".

We maintain existing PHP applications for the long term: plain PHP, Laravel, Symfony, and older frameworks like CodeIgniter, CakePHP, Yii and Zend Framework — you don't need to know which one your system uses; we'll figure that out. We start by understanding and documenting what you have, stabilise the risky parts, and then keep the system secure, updated and steadily improving — so it stops being a source of anxiety.

If the application has been completely orphaned — no documentation, no access, no handover — start with our application takeover process. If the codebase needs deeper structural work, see legacy PHP modernisation. If you already know your system is a Symfony application, we have a page for Symfony support and maintenance.

We do not insist on a rewrite

We have supported and improved legacy Symfony and PHP applications for years — we don't insist on a rewrite.

The database is part of the job

MySQL and PostgreSQL upkeep, slow queries, and version migrations — like the MySQL 5.7 → 8.0 move that cut ~$900/month in AWS costs for a client.

One partner, no finger-pointing

Code, database, hosting and integrations under one roof — no finger-pointing between vendors.

how it works

from risky to routine

Assess

A System Risk Check of code, database, hosting, backups and integrations. You get a written risk report.

Stabilise

Fix the things most likely to take you down: failing jobs, fragile deploys, unpatched dependencies, missing backups.

Maintain

Ongoing fixes, updates, monitoring and small improvements under a clear monthly arrangement.

Improve

Performance work, refactoring, version upgrades and new features — at the pace the business needs.

FAQs

PHP maintenance questions

Yes — end-of-life PHP versions are our normal workload. We support the system as it is while it is stabilised, then usually propose a staged path via version upgrades so you stop accumulating security and compatibility risk.

No. Plain PHP, CodeIgniter, CakePHP, Yii, Zend Framework, something custom — identifying what you actually have is part of the initial audit, and you don't need to know it to get started.

No. Stabilise first: backups, security patches, monitoring and the riskiest failures. Modernisation happens later, incrementally, and only where it pays for itself.

A monthly retainer sized to your system and how fast it changes, agreed after the System Risk Check. Larger pieces of work are estimated up front and billed for time actually worked — see how pricing works and How We Work.

testimonials

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.

Pilar Bordonado

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.

Kakhaber Zaalishvili

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.

Victoria Kurashkina

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.
