Backend Developer
Category : Web development
A backend-focused software engineer with over six and a half years of experience building scalable, reliable systems for product-driven applications. My core expertise is in Node.js and Python, where I’ve designed and developed RESTful APIs, microservices, and serverless architectures used in production at scale. I have strong experience with relational and NoSQL databases such as PostgreSQL, MySQL, MongoDB, DynamoDB, and Redis, with a focus on performance, data modeling, and system reliability.
I’ve worked extensively with cloud platforms like AWS and Google Cloud, contributing to cloud-native designs, CI/CD pipelines, monitoring, and infrastructure automation, as well as participating in large-scale cloud migrations.
I enjoy working in fast-paced environments where backend decisions directly impact users and business outcomes. I’m adaptable, proactive, and quick to learn new technologies to deliver effective, scalable solutions

- I will manage your backend and cloud services at the most efficient ways possible to perfect your billings!1000 $ - Per hourWhat I can help you with: - Backend API development with Node.js / TypeScript - REST APIs & Microservices Architecture - AWS Serverless Architecture - PostgreSQL / MongoDB database design & ...
– Orchestrated the cloud migration of a critical suite of microservices powering 30+ production
websites from Azure to GCP, ensuring zero downtime and full end-user continuity throughout the
transition.
– Architected and managed serverless microservices on AWS, leveraging Lambda, DynamoDB,
API Gateway, and CloudFormation for a major restaurant chain’s ordering and delivery platform.
– Engineered a real-time differential delivery pricing module, integrating live pricing signals into the
order flow and improving delivery accuracy for end customers.
– Designed and implemented a reusable dynamic scheduling framework driven by database
records to automate data-extraction and migration jobs, eliminating significant manual intervention and
improving Power BI reporting efficiency.
– Established a standardised Git-based workflow replacing Azure Pipelines, measurably improving
CI/CD velocity and deployment consistency across the engineering team.
– Designed and maintained AWS CloudFormation Templates (CFTs) to provision and versioncontrol Lambda infrastructure, ensuring repeatable, auditable deployments across environments.

– Built image and video manipulation pipelines for thumbnail generation, media compression, and
streaming — powering media delivery across the platform.
– Engineered web scrapers to extract and aggregate data from multiple popular e-commerce sites into a
unified platform (GoodPix), with Redis caching to handle large response payloads efficiently.
– Optimised complex MongoDB queries for large datasets across game server projects (Indian Rummy,
Dominoes, Vedashow), significantly improving API response times.
– Led backend development for PTFinder from scratch, integrating RabbitMQ for async messaging
and multiple payment merchant gateways.
– Implemented real-time features using Socket.io for live game state, notifications, and multi-user
synchronisation across several production titles.
