About Me
from microservices to monitoring.
I'm a Backend Software Engineer at Cognam Technologies with 3+ years of experience designing and shipping enterprise-grade systems. My work spans real-time logistics tracking, distributed notification pipelines, and AI-powered data tools.
I specialize in Java & Spring Boot ecosystems — from SOA monoliths to event-driven microservices with Apache Kafka. I care deeply about performance, observability, and writing code that scales without breaking.
Beyond coding, I've mentored junior developers, led demos with cross-functional teams, and volunteer with Robin Hood Army to support food distribution and education initiatives.
Experience
- Built a reusable heartbeat monitoring system using ActiveMQ (Pub-Sub) & MQTT to track health metrics across 10+ internal products, enabling scalable external onboarding.
- Improved search speed by 70% and reduced storage by 60% in the logistics tracking system via index cleaning and query refactoring.
- Constructed an audit feature for real-time device accuracy monitoring; delivered PDF/Excel analytical reports that accelerated stakeholder decisions by 40%.
- Integrated OpenAI API to build an AI-powered insights feature, enabling natural language queries over logistics data.
- Worked across two products simultaneously, delivering scalable solutions in real-time tracking and logistics monitoring.
- Designed an Employee Management System using Java 17, Spring Boot, Spring Security, and MySQL.
- Fixed 50+ backend issues including API bugs, exception handling, dashboard restore failures, and query optimization.
- Added multilingual support via localization and adopted Agile workflow with Jira, sprints, and daily scrums.
Projects
Scalable backend for multi-channel notifications (Email, SMS, Push). Asynchronous event-driven architecture built to handle massive throughput with full observability.
Full-stack web application for virtual therapy and mental health support. Secure therapist-patient video sessions with appointment booking and payment integration.
Spring Boot backend for controlling a remotely operated probe exploring the ocean floor. Navigation rules live in the domain layer with a stateful REST API — grid boundaries, obstacles, and probe position driven by YAML config and in-memory state.
A fitness application backend built to master the fundamentals of microservices architecture. Designed as a hands-on learning exercise exploring service decomposition, inter-service communication, and Spring Boot patterns.
