At NXGenius Pvt. Ltd., I built a fintech payment portal end to end and owned its architecture, delivery, and operations. Atomic database locking and strict transaction management prevented race conditions and double-spend under concurrent load.
I also implemented encrypted storage, audit logging, role-based access control, and hardened session management for the portal. A multi-channel OTP and notification system connected SMS and email providers with retry logic and delivery tracking.
For Project Opeline, I extended an established CRM by building a Private Documents module with secure storage, permissions, versioning, and an audit trail. I also delivered task management workflows and internal REST APIs for Inertia.js/React screens and a Next.js client.
On a side project, I built a modular CRM for UHNWI-focused agencies, with a Laravel API core and client-facing interfaces in Inertia.js, React, and Next.js. I added automated pull-request analysis to surface security and performance risks before review.
