I'm a backend software engineer with 3.10+ years of experience building distributed, cloud-scale systems. I specialize in Python, Django, and FastAPI — designing APIs, high-throughput event pipelines, and caching layers that handle real workloads at scale.

I've built and scaled a cloud-scale network management platform serving 20,000+ active devices, a real-time PCB manufacturing execution system, and I am currently architecting and building Jobspiq — an AI-native job aggregation platform.

I thrive on end-to-end system ownership, solving performance bottlenecks, and building highly resilient backend architectures that scale seamlessly.

Systems design
Designing scalable backends — APIs, event pipelines, caching — built to handle real production load, not just demos.
Performance & reliability
Reduced latency by 40%, cut server load by 45%. I find bottlenecks and fix them with data, not guesswork.
Async & distributed
RabbitMQ, Celery, Redis — building decoupled systems that keep working even when individual parts fail.

Oct 2022 – Present
S3DT — Real-Time Camera Acquisition System
Jan 2026 – Present
Python FastAPI Multiprocessing WebSockets FFmpeg NumPy FLIR SDK Linux
  • Architected a high-performance 8-camera acquisition system capable of recording synchronized 291–300 FPS video streams with zero frame loss through multiprocessing, shared-memory pipelines, and optimized capture strategies
  • Redesigned desktop acquisition software by migrating from Tkinter to a FastAPI web architecture, enabling browser-based control, monitoring, and simplified deployment
  • Built a real-time streaming pipeline using WebSockets, allowing low-latency live previews of all connected cameras over the local network while recording high-speed video simultaneously
HFCL — Element Management System
Oct 2022 – Present
Python Django REST Cassandra RabbitMQ Celery Redis Kubernetes Docker
  • Architected backend services for a cloud-scale EMS platform managing 20,000+ network devices — high-throughput telemetry ingestion using Django REST and Cassandra
  • Built async event pipelines with RabbitMQ and Celery for decoupled, fault-tolerant processing of device configuration and alert events at scale
  • Designed a Redis caching layer and optimized Cassandra bulk-write pipelines — cut DB calls by 30%, reduced server load by 45% under peak traffic
  • Improved batch processing by 20% using Pandas pipelines and Python threading for parallel device polling
  • Deployed services on Kubernetes with Docker — zero-downtime rollouts in production
MExS — Manufacturing Execution System
Oct 2023 – Apr 2024
Python FastAPI PostgreSQL Redis Celery Docker Linux
  • Built a real-time PCB traceability system using FastAPI and PostgreSQL — tracking board lifecycle across 8+ SMT assembly stations with per-stage pass/fail logging
  • Automated defect detection and rejection logging via Celery async tasks — reduced manual QA effort and improved audit turnaround time
  • Designed PostgreSQL schemas for manufacturing and traceability data, enabling compliance-ready audit trails
  • Led requirement-gathering with production and quality teams, translating shop-floor workflows into sprint features
  • Drove live production deployments and resolved on-site issues — zero disruption to the assembly line
