Zoho & CRM Integration Expert | API Architect (15+ yrs, Top Rated Plus

15+ years turning messy, disconnected systems into automated, reliable workflows. I'm an API & Integration Architect specializing in connecting CRM, ERP, and finance platforms — Zoho (CRM, Creator, Books), Infusionsoft/Keap, Stripe, Xero, and custom web databases. Clients bring me two-way sync problems, broken legacy integrations, and "these systems don't talk to each other" headaches — I design the architecture first, then build it clean and scalable. Recent work: - Built and maintain a Zoho–Robaws integration currently in its second year (700+ hrs) - API/webhook integration for Axonius & Google SecOps (Chronicle) - 2,000+ hours resolving and maintaining Google Calendar API issues for a long-term client - Backend architecture for a client portal (6,200+ hours, ongoing since 2021) Why clients keep me long-term: ✓ 100% Job Success Score, Top Rated Plus ✓ $400K+ earned across 46 projects, most with repeat/ongoing engagements ✓ I respond fast (avg. 0-4 hrs) and I'm not a 9-to-5 contractor — I'm available when you need me ✓ I explain trade-offs in plain English before writing a line of code, so you're never surprised later Stack: PHP, Python, Django, RESTful APIs, OAuth, Zoho Platform, Infusionsoft, Stripe, Xero, Google APIs, MySQL, business process automation. Let's talk about what's broken or what you're trying to build — I'll tell you honestly what it'll take.
