Your tools don't talk to each other. Your team copies data by hand. Your app can't grow because the backend can't keep up.
Every day that continues, you're paying for it in wasted hours, errors, and lost customers.
I build APIs that fix that.
WHAT YOU GET
Custom REST APIs designed around your exact business logic
Clean, well-documented endpoints your team can actually use
Secure authentication (API keys, JWT, OAuth) and rate limiting
Third-party integrations: payment gateways, CRMs, WhatsApp, GST and government portals, and more
Built to scale, so traffic spikes don't crash you
Full documentation and testing, so nothing breaks after handover
HOW IT WORKS
Discovery call: we map your systems, data flow, and goals
API design: you approve the endpoints before I build
Development + testing: built, secured, stress-tested
Launch + handover: live, documented, supported
WHO THIS IS FOR Startups, SaaS founders, and businesses that want their apps, websites, and tools to work together seamlessly, without hiring a full in-house dev team.
WHY ACT NOW I only take a limited number of projects each month to keep quality high. Once slots are full, the next opening is weeks away, and every week of manual work and broken workflows is money you don't get back.
Hit "Book" and let's get your systems talking.
