We build backends that your product can grow on: well-structured APIs, multi-tenant SaaS cores, and domain-heavy systems that behave the same in staging, during a demo, and when real traffic shows up.
ColibriCode is based in Denver, USA, partnering with teams that run their business on Symfony and Laravel platforms.

WHY SYMFONY & LARAVEL
Symfony and Laravel give us a reliable core for complex domains, while the rest of your stack—React/Next.js, Python, Go—plugs into it through clean interfaces instead of ad-hoc shortcuts.
LONG-LIVED APIs
We put effort into API boundaries so mobile apps, web apps, and partners can evolve without constant breaking changes.
BUSINESS-FIRST DESIGN
We organize code around the language your business uses, so features are easier to reason about and safer to change.
TEAM OWNERSHIP
Documentation, diagrams, and clear module boundaries help new engineers onboard without relying on “tribal knowledge”.
HOW WE BUILD
We design APIs that feel predictable, well-versioned, and easy for other teams to build against.
From pricing plans to tenant isolation, we treat multi-tenancy as a first-class concern, not an afterthought.
When the real complexity lives in rules, workflows, and edge cases—not in the UI.
We prepare your Symfony/Laravel app for real traffic, not just staging demo data.
ARCHITECTURE PATTERN
The backend owns identity, permissions, and business rules. React/Next.js, Python, and Go connect via well-defined contracts instead of tightly coupled hacks.
SYSTEM VIEW
Symfony / Laravel as the business core
Owns authentication, authorization, domain logic, and external integrations (billing, CRMs, ERPs, etc.).
React / Next.js as the UI layer
Renders dashboards, admin panels, and customer experiences using data and auth from the PHP backend.
Python for data & automation
Pipelines, analytics, ETL jobs, and ML services that consume and enrich backend data.
Go for high-throughput workloads
Queues, workers, and streaming services where latency and concurrency really matter.
Shared observability layer
Logs, metrics, and traces that let you follow a request from UI to PHP to Python/Go and back again.
WHAT THIS FEELS LIKE DAY-TO-DAY
Product managers can reason about flows in terms of business actions, not controller filenames and random jobs.
Frontend engineers have clean contracts and don’t need to dig into backend internals for every UI change.
Ops teams know where business rules live and can roll back, hotfix, or toggle behavior without chaos.
When traffic spikes, you scale the right layers instead of throwing bigger servers at everything at once.

FAQ
When do you choose Symfony vs Laravel?
We use both. Symfony is often our choice for highly structured, long-lived platforms with many internal services. Laravel is excellent when speed of delivery, batteries-included tooling, and developer experience are top priorities. We’ll discuss your team, roadmap, and constraints before recommending one.
How do you handle multi-tenancy safely?
We avoid ad-hoc tenant checks scattered everywhere. Instead we centralize tenant resolution, design tenant-aware models, and add guardrails at the data and application layers. We also think about support workflows, migrations, and backups from day one, so tenants stay isolated and recoverable.
Where do Python and Go fit in a Symfony/Laravel stack?
Symfony or Laravel often act as the core "business API". Python is great for data, ML, and glue services; Go shines for high-throughput APIs, workers, and pipelines. We place each language where its strengths benefit the platform instead of forcing PHP to do everything.
Can you integrate with our existing systems?
Yes. Many of our backends connect to ERPs, CRMs, payment gateways, and internal services. We treat integrations as first-class citizens: explicit adapters, clear failure modes, and observability around every external call.
TALK ABOUT YOUR BACKEND
Share a short description of your current stack, biggest pain points, and what a successful backend would unlock for your team. We'll reply with how we'd approach it—and whether we're the right fit.
A couple of paragraphs and a list of systems you integrate with is enough for a first pass—no 40-page spec required.
