WHAT I'VE BUILT
Database-Per-Tenant Multi-Tenant SaaS & HRMS Platform
Architected a database-per-tenant PostgreSQL architecture with a centralized master database for tenant registration, billing, licensing, and automated tenant-provisioning engine. Built HRMS with dynamic RBAC, employee management, payroll, leave, attendance, shift scheduling, and Azure Blob Storage integration on Azure VMs.
- Cut client testing and production setup time by up to 25%.
- Dynamic Role-Based Access Control (RBAC) with approval hierarchies.
Ather EV Component Test Bench
RS232-based PERN stack test bench with configurable multi-step test workflows for EV components. Replaced manual notebook/Excel-based testing, cutting overall testing time by 25% and accelerating component delivery and report turnaround.
- Configurable multi-step test workflows for EV components.
- Reduced testing time by 25% replacing manual notebook logging.
IoT-Based Transformer Test Bench
IoT-based MERN stack platform integrating RS232 instruments (Vasavi, Microtest, Yokogawa) for automated electrical testing and report generation, reducing production time by 10% and now powering 95% of client's production reporting.
- Integrated Vasavi, Microtest, Yokogawa test instruments via RS232.
- Automated electrical metric calculations and test execution.
MQTT Industrial Oven Automation Platform
MQTT-based PERN stack platform integrating temperature controllers for real-time monitoring, automated temperature control, emergency controls, and giving operators live visibility into temperature dilation, fluctuation, and curing cycles.
- Real-time MQTT telemetry and automated curing cycle synchronization.
- Live operator visibility into temperature dilation & batch status.
