Full-Stack Development

Complex business logic, built to last.

When the off-the-shelf tool can't model your workflow — the permissions, the approvals, the commissions — you need custom software. We build the systems that run operations.

In short

Full-stack development is building custom web applications end to end — front end, back end, database and integrations. FIMM's senior Laravel and React team builds CRMs, ERPs, SaaS products, admin panels and REST APIs with role-based access and the complex business logic — workflows, approvals, reporting, commissions — that off-the-shelf tools can't handle. This very site runs on our Laravel stack.

What we build

What we build.

A

Custom CRM

CRMs shaped around your pipeline and process — not a generic tool you bend your business to fit — with the automations and reporting your team actually needs.

B

ERP systems

Inventory, orders, finance and operations tied into one system, with the workflows and approvals your business runs on.

C

SaaS products

Multi-tenant SaaS with billing, plans and dashboards — built on foundations that scale from first customer to thousands.

D

Admin panels

Powerful internal tools and dashboards that replace spreadsheets and manual ops, with the controls your team needs and nothing it doesn't.

E

REST APIs

Clean, documented APIs that power your mobile apps, partners and integrations — versioned, authenticated and built to last.

F

Payment integrations

Stripe and other gateways integrated properly — subscriptions, invoicing, webhooks and the reconciliation logic behind them.

G

Role-based access control

Granular permissions, roles and audit trails so the right people see and do exactly the right things — no more, no less.

How it ships

Scoped, guardrailed, owned.

Automation only earns trust if it's reliable. Here's how we keep it that way.

01

Map

We map your workflows, roles and data model before a line of code — so the software fits the business.

02

Architect

We design a clean architecture on Laravel and React that will hold up as complexity and load grow.

03

Build

Working software in weekly checkpoints you control, with the complex logic tested and reviewed.

04

Manage

Optional retainer to maintain, extend and scale the system as your business changes.

Frequently asked

Common questions.

Do you build custom CRMs?
Yes. We build CRMs shaped around your actual pipeline, roles and automations rather than forcing your process into a generic tool — including reporting, permissions and the integrations your team relies on.
Can you build an ERP system?
Yes. We build custom ERP systems that tie inventory, orders, finance and operations into one platform, with the workflows and approval rules your business runs on.
What is your tech stack?
We build on Laravel (PHP) and React, with MySQL or PostgreSQL, REST APIs, and deployment on GCP and AWS. This very website is Laravel-built — the stack we use for client systems.
Do you build REST APIs and integrations?
Yes. We build clean, documented, authenticated REST APIs to power mobile apps, partner integrations and third-party services — with versioning and real error handling.
Can you add role-based access control?
Yes. Granular roles, permissions and audit trails are a standard part of what we build, so the right users can access exactly the right data and actions.
Laravel or React — which do you use?
Both. Laravel powers the back end, APIs and business logic; React powers rich, interactive front ends. We pick the right blend per project, and this site itself runs on Laravel.
Can you take over an existing Laravel or React codebase?
Yes. We regularly take over and extend existing Laravel and React codebases — reviewing what's there, stabilizing it, and building on it as your ongoing team.
