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.
Ongoing ownership of live applications: monitoring, bug fixes, security updates, incidents, cron jobs and queues.
Developer gone? We take over inherited systems: secure access, map the risks, stabilise, then own it long term.
Legacy PHP modernisation and safe Laravel, PHP and database version upgrades — no big-bang rewrite.
Framework-specific maintenance: queues, schedulers, Eloquent performance, upgrades and production reliability.
New features for existing products and integrations with payment, availability, pricing and operational systems.
A structured technical audit of your application — know the risks before they become incidents.
trusted by worldwide clients since 2024.
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.
Case studies
Maintenance & Support Laravel maintenance for two established travel websites
How we took ongoing technical ownership of two live Laravel travel websites — cutting a key search page from about 17 seconds to about 1 second along the way.
Maintenance & Support Stabilising an inherited Laravel platform nobody dared to restart
A half-finished Typo3-to-Laravel migration, a 15 GB repository and a production server nobody dared to reboot. Audit first — then backups, security fixes, Docker and ~500 tests.
Modernisation & Upgrades MySQL upgrade that cut about $10k a year in AWS costs
An outdated MySQL 5.7 database was quietly adding about $900 a month in AWS Extended Support fees. We planned and ran a safe upgrade to 8.0 around a live legacy application.
