Services for Existing PHP, Laravel & Symfony Applications

We keep business-critical PHP, Laravel and Symfony applications running, secure and moving forward.

what we do

your application, in reliable hands

Most of our clients come to us with a system that already exists: a SaaS product, a booking platform, an e-commerce backend or an internal business tool. We take responsibility for it — stabilise it, maintain it, modernise it and keep improving it.

Ongoing care for live PHP, Laravel and Symfony applications: monitoring, bug fixes, security patches, incident response, cron jobs, queues and databases.

Incremental modernisation of legacy PHP systems and safe framework, PHP and database version upgrades — without a risky big-bang rewrite.

New features for existing products and integrations with payment, availability, pricing, e-commerce and operational systems — built and then maintained.

A structured review of your code, infrastructure, database and deployment setup. Know exactly what you own and what could break — before it does.

application takeover

If the people who built your application are no longer around, we take it over in a structured way: access audit, risk map, stabilisation, then long-term ownership.
How an application takeover works →

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 it fits together

Assess first, stabilise next, then stay

Almost every engagement follows the same path, whichever service brings you here. It starts with a System Risk Check — a structured audit that turns an unknown system into a written, prioritised risk report. The urgent risks are then removed as time-and-materials work, estimated up front. Once the system is stable, it moves onto a monthly maintenance retainer — and the knowledge of your system stays with one accountable team instead of walking out the door again.

The full process, step by step, is on How We Work; what each stage costs and why is on Pricing.

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.

Valentyn and his team helped us build a flexible backend system to manage training sessions, client materials, and participant feedback. What stood out was their ability to translate our needs into a clean, functional platform. Their calm, clear communication and dependable delivery made the whole process feel effortless. And, Valentyn himself, is a thoughtful leader with incredible skills. 10 out of 10 would recommend!

We worked with Valentyn’s team on integrating our AI automation platform with several third-party services via custom APIs. They quickly understood the technical requirements and delivered a clean, well-documented solution that worked out of the box. Their work helped us reduce onboarding time for new clients and made our system much easier to scale. Great communication, fast iterations, and no surprises - highly recommended!

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.

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.
