Visual AI Advisor (VAIA)

• Migrated a monolithic C# backend to an async FastAPI + Django ORM platform, developing 40+ REST APIs endpoints across 10 modules, reduced p99 API latency from 400ms to sub 100ms while ensuring zero-downtime.
• Built a real time event pipeline for IoT edge devices,from edge cameras over MQTT, processed by Celery/Redis workers that validate and deduplicate alerts through a multi stage chain before dispatching Email/WhatsApp notifications with capped 3 retry fault handling, autoscaled via Kubernetes HPA.
• Redesigned a legacy circuit-breaker design pattern into a Python singleton pool for Cloud Storage, adding proactive token refresh and semaphore based concurrency limits to eliminate connection exhaustion under heavy upload bursts.
• Rearchitected media delivery by replacing a Python proxy bottleneck with GCS/CDN Signed URL redirects, leveraging keyless IAM authentication in GKE to offload media traffic to edge nodes, eliminating resource strain.
• Improved scalability and reliability of scheduled report generation by implementing a Celery + Redis async pipeline, dispatching 6 report types across multiple workers with automated PDF/Excel delivery.

Central Asset Manager (CAM)

• Built a multi tenant asset management platform on Django REST Framework and PostgreSQL, supporting organization hierarchies, user management, and asset tracking across isolated tenants.
• Developed automated unit and integration test suites using Django Test Framework and Pytest, improving API reliability and validating multi-tenant access controls, business workflows, and database operations.
• Integrated Svix webhook service for event-driven notifications to external consumers, including signature verification for payload authenticity.
• Automated multi-cloud deployment across GCP and AWS environments (Dev, Sandbox, UAT, Production) with a 3 stage Bitbucket Pipeline flow per environment (Test → Docker Build → Helm Deploy).
