ARCHITECTURAL FOUNDATION & ROLE

As Lead Backend Developer at Avisa Technologies, I architected the sensitive data storage and scheduled delivery pipelines. I built a cryptographic vault system that encrypts personal farewells, video notes, and legal instructions at rest using AES-256 GCM encryption.

Key Engineering Highlights & Features

Cryptographic Digital Vault with AES-256 GCM Encryption

Multi-Signature Trusted Contact Release Protocol

High-Capacity Audio & HD Video Streaming Uploads

Automated Lifecycle & Inactivity Verification Triggers

Web Admin Portal for Compliance & Ticket Management

Tamper-Proof Audit Logging & Scheduled Dispatch Engine

A cornerstone of the system is the Multi-Signature Trusted Release Protocol. I engineered verification workflows that require designated trusted contacts to validate confirmation milestones before any encrypted archives are unlocked and dispatched to recipients.

ApresVee Admin Dashboard & Production Metrics

I developed the Web Admin Management Portal to give operations teams oversight of verification tickets, legal compliance requests, storage allocation, and platform health, all enforced by strict role-based access control.

PRODUCTION RELIABILITY & SCALE

The backend utilizes streamed chunking for reliable handling of heavy multimedia assets, automated cron validators, and idempotent delivery workers that ensure messages are delivered accurately without duplicate transmissions.
