Symfony development services
Symfony development services for web applications and back offices, REST and GraphQL APIs on API Platform, SaaS and enterprise systems, Sylius and Shopware shops, payment and billing services, Drupal, Pimcore and other platforms built on Symfony, and upgrades of older Symfony applications, with dedicated Symfony developers for your team or a Symfony project delivered end to end.
What we build with Symfony
Symfony web applications
Customer portals, back offices and line-of-business systems on current Symfony releases, with Doctrine entities and migrations, forms and validation, voters for authorisation, EasyAdmin for internal screens, and Symfony UX with Turbo and Live Components for interactive pages without a separate front end.
APIs on API Platform
REST and GraphQL APIs described from PHP classes with API Platform, with Hydra and OpenAPI documentation generated from the code, validation, filters and pagination, Mercure for real-time updates, and clients for Next.js, Nuxt or Expo generated from the same description.
SaaS and enterprise products on Symfony
Multi-tenant products, ERP and CRM add-ons and workflow systems meant to run for a decade, with the Workflow component for approvals and state machines, single sign-on through OpenID Connect to Entra ID, Okta or Keycloak, and roles checked in voters on every request.
Sylius and Shopware shops
Online shops, B2B portals and marketplaces on Sylius, Shopware or OroCommerce, all built on Symfony: custom plugins, pricing and checkout rules, payment and delivery integrations, and catalogues and stock kept in step with your ERP and PIM.
Payment and billing services on Symfony
Payment, lending and subscription billing back ends with money held in integer minor units, Doctrine transactions that lock the affected rows around every balance change, open-banking and card providers behind adapters, and signed webhooks processed exactly once.
Messenger queues and integrations
Work moved out of the request with Symfony Messenger over RabbitMQ, Redis, Amazon SQS or Doctrine transports, recurring jobs on the Scheduler component, and calls to ERP, CRM and partner APIs through HttpClient with timeouts, retries and a failure transport that alerts someone.
Symfony upgrades and LTS moves
Applications on Symfony 2 to 6 moved to the 7.4 long-term support release or to Symfony 8 through each major version’s last minor release, with deprecations cleared from the logs first, Rector making the mechanical changes and tests added ahead of each step.
Platforms built on Symfony
Modules for Drupal, which runs on Symfony components, and bundles for Pimcore, Ibexa DXP, Akeneo PIM and Mautic, written against each platform’s extension points so its core is never patched and stays upgradable.
Symfony performance and caching
Slow pages traced with Blackfire to the query or call behind them, HTTP caching and the Cache component on Redis, FrankenPHP in worker mode where it helps, and containers on Azure, AWS or Google Cloud with the infrastructure as code.
Hire Symfony developers
Dedicated Symfony developers
Symfony developers who join your team full time, work in your repositories, tracker and meetings, and report to your lead. You interview them; we carry the Ukrainian contract, payroll, invoicing and leave.
Symfony project delivery
A team that takes the Symfony project from scope to release: estimate, build, tests and deployment, with a technical lead on our side who owns the plan and the quality.
Symfony support and take-overs
An existing Symfony system taken over from another team or kept running: a read-only review and a written list of risks first, then fixes and new features in order of impact.
The dedicated team page explains how specialists join your team, and the outsourcing page covers project delivery, take-overs and how we charge.

How we work on Symfony
Current Symfony and PHP releases, or the long-term support release where a system needs years of fixes without a major upgrade. Strict types, PHPStan at the strictest level the code can reach, PHPUnit tests that ship with each feature, authorisation in voters, every query through Doctrine with bound parameters, secrets in a vault rather than in committed .env files, and security advisories treated as unconditional upgrades.
Developers work in your repositories, your tracker and your process. The Ukrainian contract, payroll, invoicing and leave stay with us, and everything they write is assigned to you.

Questions about Symfony development
Which industries do your Symfony developers work in?
Mostly e-commerce and retail: shops, B2B portals and marketplaces on Sylius, Shopware and custom Symfony code. Then fintech, with payment, lending and billing services; SaaS and enterprise software, with ERP, CRM and workflow products; healthcare, with booking and patient portals; adtech and marketing, with campaign and tracking platforms; and media and publishing, with content platforms. Logistics and education products are common too.
Which Symfony versions do you work on?
Every maintained branch: Symfony 8 for new work, the 7.4 and 6.4 long-term support releases, and older versions that need to be brought forward. Applications on Symfony 2, 3 or 4 are upgraded step by step, each step released on its own, rather than rewritten.
Do you also work on Sylius, Shopware and Drupal?
Yes. All three are built on Symfony or its components, so Sylius and Shopware plugins and Drupal modules are part of the same work as plain Symfony code. Drupal sites in full are covered on our Drupal development page.
How quickly can Symfony developers start?
When the right Symfony developer is available, the start is gated only by your interview and the NDA and IP assignment. Otherwise we run a search, which typically produces candidate profiles within two to three weeks, and nobody starts until you have said yes.
How do we hire Symfony developers through BigTree108?
Tell us the work, the seniority and the hours you need. We propose one or two people with their profiles, you interview them the way you would interview your own hire, and you sign one agreement with BIG TREE 108 LLC and receive one invoice a month.
Who owns the work they produce?
You do. Every specialist has a signed contract with BigTree108 that assigns all work product to the company, and our agreement with you assigns it onward. Code, designs and documents are delivered into your own repositories and tools, not kept where only we can change them.
Building on Symfony?
Tell us the Symfony and PHP versions and what the system does. You get an answer within one business day: a plan for the work, an upgrade plan or candidate profiles.
