Our Cases

Backend Development Built for Scale, Security, and Performance

We engineer reliable backend systems that power modern digital products — fast, secure, and built to scale.

Our backend development services help businesses and digital agencies across the United States launch, expand, and maintain robust infrastructures that support millions of users without compromise.

We specialize in API development, database design, serverless architecture, and system integration — transforming your technical foundation into a future-proof, high-performance engine.

API Development (REST & GraphQL)

Every successful application relies on a solid communication layer.

Our team builds RESTful and GraphQL APIs using Node.js, Express, and TypeScript, ensuring your systems exchange data quickly, securely, and efficiently.

We design APIs that are versioned, well-documented, and optimized for real-world usage — whether you need public developer access or internal microservice communication.

Authentication (JWT, OAuth 2.0), rate-limiting, and error-handling are implemented from day one, guaranteeing performance, reliability, and compliance with modern security standards.

Our API solutions seamlessly integrate with frontend, mobile, and third-party platforms, giving you full control over data and user experience.

Database Design & Optimization

A powerful backend depends on a well-structured data layer.

We design, configure, and maintain SQL and NoSQL databases — including PostgreSQL, MySQL, MongoDB, and Redis — ensuring every query performs at peak efficiency.

Our engineers focus on:

  • Schema design & normalization for scalability and maintainability
  • Indexing & query optimization for high-volume traffic
  • Migration & backup strategies for data security
  • Load balancing & replication for uptime and consistency

We also handle analytics databases and time-series solutions for product metrics, IoT, or AI platforms — giving your team actionable, reliable data.

Serverless & Microservices Architecture

Modern applications demand flexibility.

We architect serverless and microservices ecosystems using AWS Lambda, Docker, and Kubernetes to eliminate downtime and reduce operational costs.

Our approach allows you to deploy independent services that scale automatically — ideal for SaaS platforms, e-commerce systems, and enterprise APIs.

We also provide continuous integration and automated monitoring, so your backend evolves without manual intervention.

Serverless solutions built by TOP offer reduced infrastructure overhead, enhanced fault tolerance, and predictable costs aligned with usage.

Payment & Integration Services

We enable your platform to connect seamlessly with the world’s most trusted payment and third-party systems.

Our developers implement Stripe, PayPal, Braintree, Plaid, and custom API integrations for billing, subscriptions, and marketplace transactions.

For SaaS and e-commerce projects, we build secure PCI-compliant flows with full audit logs and webhook handling.

We also integrate CRMs, marketing tools, and ERP systems, ensuring your business ecosystem works as one connected entity.

Whether you’re automating invoicing or syncing external data sources, TOP delivers smooth, resilient integrations tailored to your workflows.
