What We Build

Custom Backend Development Services

From business logic to data storage to third-party integrations — we handle the full server-side stack so your application runs smoothly, securely, and at any scale. Every decision is made with long-term maintainability in mind, so you're never stuck with code that can't grow with you.

Custom Backend Architecture

We design server-side systems tailored to your product — whether that's a monolith, microservices, or event-driven architecture. The right choice depends on your team size, traffic patterns, and growth trajectory. We make that call with you, not for you, and build it to scale without needing a rewrite six months later.

  • Microservices and monolith design
  • Event-driven architecture with RabbitMQ
  • Domain-driven design (DDD)
  • Scalable from day one

Business Logic & Application Layer

The rules that make your product unique live in the backend. We implement your business logic cleanly, test it thoroughly, and structure it so it stays maintainable as requirements evolve — because they always do. No spaghetti code, no shortcuts that come back to bite you.

  • Java / Spring Boot 4 application layer
  • Node.js services for real-time features
  • Automated unit and integration tests
  • Clean, maintainable codebase you own

Database Design & Management

Fast, reliable data storage is non-negotiable. We design schemas that reflect your domain, optimize queries before they become bottlenecks, and choose the right database for your workload — relational or document-based. Good database design is invisible to users; bad design isn't.

  • PostgreSQL — schema-per-tenant isolation
  • MongoDB for document-based workloads
  • MySQL for relational data needs
  • Query optimization and indexing

API Development & Integration

We build the APIs that connect your frontend, mobile apps, and third-party services — documented, versioned, and secured from the start. A well-designed API is a contract your whole team can rely on, and we treat it that way.

  • RESTful API design and development
  • OpenAPI / Swagger documentation
  • Third-party service integrations
  • Webhook implementation and handling

Backend for Web Applications

From enterprise platforms to social networks to multimedia apps — we build the server-side layer that handles your data, users, and business rules at any scale. Whether you're serving hundreds of users or hundreds of thousands, the architecture holds up.

  • Enterprise and B2B platforms
  • Social and community applications
  • Multimedia and content platforms
  • Data sync across web and mobile

Security & Authentication

Security is built into every layer — not bolted on at the end. We implement authentication, authorization, and data protection that your users and auditors can trust. Breaches are expensive; doing it right the first time is not.

  • JWT and OAuth2 authentication
  • Role-based access control (RBAC)
  • Input validation and sanitization
  • Secure data storage and encryption

Let's Talk
Our Stack

Technologies We Work With

We use mature, production-proven technologies — chosen for reliability, long-term support, and the right fit for your workload. No chasing trends, no experimental frameworks in production. Just tools that have earned their place through years of real-world use.

Java & Spring Boot

Our primary backend language. Spring Boot 4 with Java 25 — enterprise-grade, battle-tested, and built for long-term maintainability. The same stack that powers some of the world's most demanding applications.

PHP & Symfony

Modern PHP 8.4 with Symfony 7 — mature, fast, and proven at scale. A great fit for web platforms, APIs, and content-heavy applications where rapid iteration and a rich ecosystem matter.

Node.js

For real-time features, lightweight services, and integrations where speed and low latency matter most. Node.js shines when you need event-driven, non-blocking I/O at the edges of your system.

PostgreSQL & MongoDB

PostgreSQL for relational data with schema-per-tenant isolation — ideal for multi-tenant SaaS. MongoDB for flexible, document-based workloads where your data structure evolves alongside your product.

Kubernetes & Docker

Every backend service runs in containers, deployed on Kubernetes with auto-scaling, health checks, and zero-downtime rolling updates. Your infrastructure grows with your traffic — automatically, without manual intervention.

Redis, RabbitMQ & Kafka

Redis for caching and session management. RabbitMQ and Kafka for async messaging, event streaming, and event-driven architecture — so your services stay decoupled and your system stays responsive under load.

Security & Auth

JWT, OAuth2, role-based access control, and encryption built into every layer of the stack — not added as an afterthought. Security is a first-class concern from the first line of code.

Monitoring & Observability

Prometheus, Grafana, and structured logging give you full visibility into what's happening in production — so you can catch issues before your users do and make data-driven decisions about where to optimize.

Start With Our Open-Source Backend Foundation

Authentication, billing, multi-tenancy, and API gateway are already built — free, Apache 2.0 licensed. Your project starts with a production-ready backend and we build your custom features on top. Skip months of infrastructure work and go straight to building what makes your product worth using.

Already Built For You

IAM & JWT auth • Stripe billing • Multi-tenant isolation • API gateway • Kubernetes configs • CI/CD pipeline • Tenant & platform-admin React SPAs (foundation-ui-app, foundation-ui-platform-admin)

Why It Matters

Your Backend Is Your Product's Foundation

A weak backend creates problems that compound over time — slow performance, security gaps, and code that's impossible to extend without breaking something else. Getting it right from the start is always cheaper than fixing it later, and far cheaper than an emergency rewrite when you're already under pressure to grow.

  • Performance that scales

    Designed for growth from the start. When your user base grows, your backend grows with it — through horizontal scaling, caching, and architecture that doesn't require emergency refactoring when traffic spikes.

  • Secure data storage

    Your users' data is protected at every layer — encrypted at rest, validated on input, and access-controlled throughout. Security isn't a feature you add later; it's a property of the system from day one.

  • Smooth third-party integration

    Payment providers, CRMs, analytics, notifications — we connect your backend to the services your product depends on, reliably and maintainably. Integrations done right don't break when the third-party API changes.

  • Code you own and understand

    Full source code ownership, clear documentation, and a codebase your team can maintain and extend — no black boxes, no lock-in, no dependency on us to keep the lights on.

Who We Work With
  • SaaS founders building a product backend from scratch
  • Teams replacing a legacy backend with a clean, scalable replacement
  • Businesses adding a backend layer to an existing frontend or mobile app
  • Enterprises needing custom backend services integrated into existing infrastructure
