We Take Over
& Improve Existing
Web Applications
Your developer is gone, the system is fragile, or you just need a technical partner who stays. We take responsibility for the application your business runs on — and keep it running.
services we offer
We keep existing PHP, Laravel and Symfony
applications running, secure and moving forward —
from emergency takeover to long-term
maintenance and modernisation.
Maintenance & Support
Ongoing ownership of live applications: monitoring, bug fixes, security updates, incidents, cron jobs and queues.
Application Takeover
Developer gone? We take over inherited systems: secure access, map the risks, stabilise, then own it long term.
Modernisation & Upgrades
Legacy PHP modernisation and safe Laravel, PHP and database version upgrades — no big-bang rewrite.
Laravel & Symfony Care
Framework-specific maintenance: queues, schedulers, Eloquent performance, upgrades and production reliability.
Development & Integrations
New features for existing products and integrations with payment, availability, pricing and operational systems.
System Risk Check
A structured technical audit of your application — know the risks before they become incidents.
trusted by worldwide clients since 2020.
Synapse Code is the technical partner businesses call when their web application matters more than their vendor relationship does. We take over, stabilise, maintain and improve existing PHP, Laravel and Symfony systems — SaaS products, booking platforms, e-commerce backends and internal tools used daily by thousands. How we do it, step by step, is on How We Work.

Hi, I'm Valentyn
I'm Valentyn Morozov, the founder of Synapse Code. For more than 15 years I have been building and running web systems across industries — from small startups to large enterprises, including a Swiss bank — combining hands-on engineering with leading development teams. Systems I have built have processed hundreds of thousands of orders and transactions.
Synapse Code is deliberately compact: a senior team of developers and testers, scaled to each project. There is no sales department to get past — when you write to us, you talk to me, and I stay personally involved in every system we take responsibility for. You can check my background on LinkedIn.
