Backend Web Development
The Engine Room of Your Digital Product
Great frontends get attention — great backends keep businesses running. Pex Fusion builds secure, scalable server-side architecture, APIs, and databases for banking platforms, shipping portals, school management systems, emergency response platforms, airline sites, ecommerce stores, author platforms and full SaaS products.
We work with Laravel, PHP, Node.js, Python, MySQL, PostgreSQL and modern backend tooling — with security, performance and maintainability baked in from day one. Every engagement is contract-ready with MSAs, SOWs, NDAs and SLAs.
Technologies We Master
We choose the right backend stack for your project's requirements — not the flavour of the month. Whether you need a Laravel monolith, a Node.js microservices layer, a Python data backend, or a PHP legacy modernisation, we build it properly.
Laravel
Eloquent ORM, Blade templating, queues, events, jobs, and RESTful API development for robust PHP backends.
PHP
Custom PHP applications, legacy modernisation, Composer packages, and integrations that keep platforms running.
Node.js
Event-driven Node.js APIs, real-time services with WebSockets, and Express/Fastify backend development.
Python
Django and FastAPI backends, data pipelines, automation scripts, and machine-learning service integration.
MySQL & PostgreSQL
Relational database design, indexing, query optimisation, migrations, backups, and high-availability setups.
REST & GraphQL APIs
Documented, versioned APIs with authentication, rate limiting, and clear contracts for frontend and mobile clients.
Auth & Security
JWT, OAuth2, role-based access control, encryption at rest, and secure session management.
DevOps & Deployment
Docker, CI/CD pipelines, cloud hosting, monitoring, and scalable deployment strategies.

How We Work
A proven backend development process that keeps you informed and in control — from architecture design to deployment and beyond.
Discovery & Architecture Design
We understand your data, users, and scale requirements. You receive a written proposal, signed SOW, and a clear architecture diagram.
Database Design & API Contracts
Schema design, entity relationships, and API specifications are agreed before development begins — so frontend and mobile teams can work in parallel.
Build & Test
Backend development with regular demos, code reviews, automated tests, security audits, and performance benchmarking.
Deployment & Handover
Dockerised deployment, CI/CD setup, documentation, source code handover, training for your team, and a post-launch warranty window.
Monitor, Support & Evolve
Ongoing monitoring, performance tuning, feature additions, and platform evolution under a retainer or project-based agreement.
