Modern applications rely on powerful and reliable APIs to connect systems, share data, and deliver seamless user experiences. Our API Development services focus on building secure, scalable, and high-performance APIs that integrate effortlessly with web and mobile applications.

We specialize in custom API development, REST API development, and backend services that enable smooth communication between databases, front-end interfaces, and third-party platforms. Whether you need an API for a React application, mobile app, or enterprise system, we design solutions that are fast, flexible, and future-ready.

Our API development process emphasizes security, performance, and scalability. We implement authentication, authorization, data validation, and encryption to ensure your APIs are protected against unauthorized access. Clean architecture and optimized endpoints help your applications perform efficiently, even under high traffic.

We also build APIs for third-party integrations, including payment gateways, CRM systems, cloud services, and external platforms. From planning and development to testing and documentation, we ensure your APIs are easy to use, well-structured, and maintainable.

In addition to development, we provide API maintenance and support, including version upgrades, performance monitoring, bug fixing, and enhancements. This ensures your APIs remain stable and compatible as your business grows.

Frequently asked questions

Do you work remotely with clients in India and internationally?

Yes. Most work is remote with scheduled calls. On-site visits in India can be arranged for longer engagements when needed.

How do you estimate timeline and cost?

After a discovery call, you receive a written scope, milestones, and pricing — fixed, retainer, or hourly depending on clarity of requirements.

Can you maintain or extend an existing codebase?

Yes. I document current behaviour, prioritise safe changes, and ship incrementally so your users see continuous improvement.

What technologies do you specialise in?

Laravel, PHP, React, Next.js, REST APIs, MySQL, and modern JavaScript — with emphasis on maintainable architecture and performance.

How can I start a project?

Use the contact form or email to describe your goals. I usually reply with next steps and a short call to align on scope.

Why businesses choose API Development with Arun Tyagi

Whether you are launching a new product, replacing a legacy stack, or scaling an existing codebase, API Development needs clear architecture, predictable delivery, and someone who can communicate in plain language—not just ship tickets. I work with founders, agencies, and in-house teams across India (including Gurugram and Delhi NCR) and internationally on a remote-first basis, with overlap-friendly hours for calls and demos.

Typical engagements include discovery to clarify requirements, a phased roadmap, and incremental releases so stakeholders see progress early. Security, performance, and maintainability are treated as first-class concerns: validated inputs, sensible caching, logging, and documentation so your next developer is not left guessing. For API-heavy work, expect consistent resource design, versioning awareness, and integration testing where it matters most.

If you are comparing freelancers versus agencies, you get direct access to the person doing the work—faster feedback loops and fewer handoffs. When your project needs extra capacity (design, DevOps, QA), I can coordinate with your vendors or recommend trusted partners while keeping ownership of the technical direction aligned with your goals.
