001 / ABOUT

I care about latency.

SCROLL ↓

I'm a full-stack dev who genuinely enjoys backend engineering — distributed systems, real-time pipelines, the parts most people complain about.

I'm a Full Stack Developer specializing in Go, Python and the MERN stack, crafting high-performance applications that scale effortlessly.

Beyond development, I handle DevOps — seamless deployments, optimized infrastructure, and reliable system performance. From backend logic to cloud architecture, I turn ideas into robust, production-ready solutions.

CallMyDoctor

Backend Engineer

Leading backend development for a Healthcare Business Operations Platform with focus on scalable architecture, deployment automation, and production monitoring using Node.js, Docker, and modern observability tools.

  • →Architected and developed the core backend architecture for a Healthcare Business Operations Platform using Node.js, Express, MongoDB, ensuring high performance, reliability, and clean modular design.
  • →Solely responsible for end-to-end deployment and production monitoring of applications on Linux (Ubuntu) servers, ensuring stable uptime and streamlined release cycles.
  • →Containerized and deployed applications using Docker and configured environment isolation for production; improved deployment speed and reduced configuration issues.
  • →Implemented server monitoring and observability by integrating Grafana, Prometheus, and Node Exporter, enabling real-time tracking of CPU, RAM, Disk, and Network metrics across several VPS servers, significantly improving incident response time.
  • →Designed and implemented a device-fingerprinting algorithm using IP analysis, User-Agent parsing, Geolocation APIs, and TTL-based checks to identify suspicious user activity, track visits even after logout, and strengthen session integrity.

ArchStore

Backend Engineer

Built high-performance backend systems using Golang and Node.js, implementing real-time features, optimizing API performance, and achieving significant improvements in page load times and communication latency.

  • →Built real-time web integration using Golang and gRPC to stream data live to users, successfully reducing page load time from 3 seconds to 1 second for enhanced responsiveness.
  • →Developed a scalable real-time chat service using Gin and Gorilla WebSocket to enable live communication between users and vendors, integrating Redis Streams to manage message queues and ensure accurate delivery across virtual machines.
  • →Enhanced message delivery efficiency by using Redis Sets for offline message storage, which reduced average communication latency from 1.1 seconds to 200ms and supported horizontal scalability without connection bottlenecks.
  • →Optimized server-side performance with Go-based microservices to handle background processing and task queues concurrently, reducing server load times from 700ms to 300ms and improving overall user engagement.
  • →Engineered a high-performance web scraper using the Rod library to extract and integrate vendor data into the store database, enabling real-time visibility of changes to users.
  • →Refined API performance using a combination of Node.js and Go, leading to a reduction in average page load time from 500ms to 300ms.
  • →Improved data handling and query performance by tuning configurations in MongoDB and ClickHouse, achieving a 30% reduction in query overhead for large-scale data operations.
005 / NOW

Currently building.
