About Zahid Latif

I'm a full-stack and mobile engineer based in Okara, Pakistan. Freelancing since 2020 and working remotely with US teams since 2023, I cover the whole stack: React and Next.js frontends, Node.js and Python backends, React Native and native iOS apps, and the Docker/Kubernetes/CI-CD layer underneath.

For two and a half years at Xassure by eDesk (Los Angeles) I built SaaS products for insurance agencies — an AI bookkeeping platform with Plaid bank feeds and OCR receipt scanning, a no-code voice-AI calling platform, and the operations system behind a 250-person VA team. Since 2025 I've been building and maintaining Post Booking Agent, a logistics platform that automates Pakistan Post bookings for ecommerce sellers.

Along the way I've shipped 8 consumer apps to the Play Store and App Store under my own developer accounts, delivered ~50 freelance projects on Fiverr at a 4.9 rating (Level 2), and completed a BS in Computer Science at the University of Agriculture, Faisalabad in 2026.

Outside of work I'm active in CLEP, a student-run nonprofit supporting children's access to education, where I hold a leadership role. I also responsibly disclosed a TOTP replay vulnerability in OpenAI's 2FA through Bugcrowd.

He reviews the existing codebase before building, flags edge cases and scope questions before writing a line, and communicates with real clarity. When something needed troubleshooting, he diagnosed it precisely and gave me exact, step-by-step instructions that worked the first time. I'm a non-developer, and he never made that a problem.

vannoyUnited StatesRepeat client · 4 ordersFiverr review

I'm now placing my third order back-to-back, and that alone says everything. What truly sets him apart is that he builds my projects like they're his own — that level of ownership, care, and pride is rare, and it shows in every single delivery.
