API Development & Third-Party Integrations

As a business grows, its tools multiply — a website, an app, accounting software, a payment gateway, an SMS service. When these don't talk to each other, your team wastes hours copying data by hand and mistakes creep in. APIs and integrations connect everything so your systems work as one.

What I build & integrate

• Secure custom APIs — let your apps and partners exchange data safely.
• Payment gateways — bKash, Nagad, SSLCommerz, Stripe and cards.
• SMS & notifications — OTP, alerts and bulk messaging.
• AI platforms — OpenAI, Claude and Gemini built into your system.
• Shipping & couriers — Pathao, Steadfast, RedX and others.

Built reliable from the start

• Secure authentication and proper error handling.
• Retries and logging so a failed call never silently loses data.
• Clear documentation your team or future developers can use.
• Built to scale as your traffic and partners grow.

Reliable integrations let a business scale without the manual work and errors that hold teams back. I design and build secure APIs and connect the third-party services you depend on. If your systems aren't talking to each other yet, let's fix that.
