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.

1

Maintenance & Support

Ongoing ownership of live applications: monitoring, bug fixes, security updates, incidents, cron jobs and queues.

2

Application Takeover

Developer gone? We take over inherited systems: secure access, map the risks, stabilise, then own it long term.

3

Modernisation & Upgrades

Legacy PHP modernisation and safe Laravel, PHP and database version upgrades — no big-bang rewrite.

4

Laravel & Symfony Care

Framework-specific maintenance: queues, schedulers, Eloquent performance, upgrades and production reliability.

5

Development & Integrations

New features for existing products and integrations with payment, availability, pricing and operational systems.

6

System Risk Check

A structured technical audit of your application — know the risks before they become incidents.

about Us

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.

~17s → ~1s

Rebuilt a client's Laravel search page from about 17 seconds to about 1 second.

−$900 / month

Cut AWS Extended Support fees by migrating a legacy MySQL 5.7 database to 8.0.

Production Rescue

Stabilised cron jobs that were accumulating and exhausting server memory.

Loyal Clients

Client relationships that run for years — maintenance is a relationship, not a ticket queue.

the founder

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.

Laravel maintenance for two established travel websites

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.

Stabilising an inherited Laravel platform nobody dared to restart

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.

MySQL upgrade that cut about $10k a year in AWS costs

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.
