01/Dental Point Clinic (Dhaka)/2026
Dental Point Clinical Portal
A streamlined clinical portal with real-time patient appointment booking and instant WhatsApp confirmations.
Challenge
The clinic relied entirely on manual telephone coordination during operational hours, causing dropped inquiries and schedule overlaps.
Solution
Built a clean, bilingual (English and Bengali) web portal connected to Cloudflare D1 for real-time slot reservations, with webhooks triggering immediate WhatsApp notifications to both patient and receptionist.
Measured Outcome: Zero double-bookings, under 800ms initial page load, and automated booking dispatch on mobile.

Media Drop / OneApp Utility
A lightweight local utility for managing, converting, and archiving personal media without web ads or tracking.
Challenge
Online media conversion tools are filled with predatory popups, malicious redirect scripts, and privacy-violating tracking pixels.
Solution
Built a native desktop application powered by local FFmpeg routines for high-speed local audio and video conversion, requiring no external server storage.
Measured Outcome: Fast on-device conversions, offline usability, and zero personal data leakage.

Wildcard Subdomain Routing Engine
Edge-based multi-tenant router providing instant subdomain provisioning (*.zenvq.com) with sub-15ms edge resolution.
Challenge
Provisioning multi-tenant web portals traditionally requires manual DNS record management or slow reverse-proxy reloads.
Solution
Designed an edge routing middleware verifying incoming hostnames against RFC 1123 constraints and rewriting requests to isolated tenant namespaces.
Measured Outcome: Instant wildcard activation across all ecosystem subdomains with zero cold starts.
