Full Professional Bio

I build practical software systems that solve real operational and business problems. Currently working as an Embedded Software Developer at Panorama Electronics Pvt. Ltd. in Kolkata, India.

Rather than treating firmware, industrial communication, and application software as disconnected disciplines, I engineer integrated architectures—connecting physical sensors, microcontrollers, and real-time operating systems with cloud telemetry, industrial fieldbuses, and responsive operational tools.

Outside industrial firmware, I design and maintain full-stack operations platforms featuring strict double-entry inventory ledgers, state-machine order workflows, and real-time analytics dashboards.

▸Core Focus: Real-time STM32 & ESP32-S3 firmware, FreeRTOS scheduling, RS-485 Modbus RTU, and Quectel 4G LTE telemetry.

▸Domain Applications: Railway coach reservoir tracking, industrial substation asset diagnostics, and enterprise supply chain operations.

▸Direct Inquiries: Open to embedded engineering, industrial IoT, and systems firmware collaborations.

Methodology & Standards

Engineering Approach & Reliability

I engineer embedded and full-stack systems with end-to-end operational accountability. A software application is only as resilient as its hardware boundaries, data model, and transaction guarantees.

Phase 01

Domain Analysis & Constraints

Deconstruct operational workflows, hardware resource boundaries, sensor dynamics, and data integrity requirements before writing code.

Phase 02

Data Modeling & State Machines

Establish strict relational schemas, state transition graphs, and communication protocol frames to eliminate runtime ambiguity.

Phase 03

Deterministic Implementation

Develop modular firmware tasks and clean backend APIs with defensive programming, thread safety, and structured error handling.

Phase 04

Verification & Automated Testing

Validate functionality through hardware test fixtures, end-to-end integration tests, regression checks, and edge-case simulation.

Phase 05

Deployment & Telemetry

Deploy containerized services or flashed microcontrollers with remote logging, health telemetry, and actionable alerts.

Phase 06

Operational Reliability

Monitor real-world endurance, audit logs, and performance metrics to guarantee long-term field stability.
