• Fortified security of data from medical devices by developing Zcrypt—a powerful cryptographic tool (CLI, Web App & Shared Libraries) developed in C based on Open SSL 3.0 that ensures utmost protection using various ciphers (RSA & AES256) throughout the data lifecycle at speeds 179% faster than previous methods with the help of child processes, threads, SHM etc.

• Architected & developed an SSO (Single Sign On) for Quadrus App Suite, that manages licenses, subscriptions, invoices, promocodes etc for different products which is backed by an in house built OAuth 2.0 Server based on Authorization Code Grant which took care of authentication & authorization with roles & scopes using Bun.js & PostgreSQL.

• Engineered a streamlined conversion pipeline for medical device-generated binary data, facilitating seamless transformation into human-readable CSV files. Leveraged Python and SQLite to develop a Scheduler equipped with advanced features, including Continuity to prevent redundant conversions, Parallels for dynamic parallel processing akin to Kubernetes resource management, and Relativity for precise timestamp adjustments relative to other systems which was licensed & distributed in AWS.

• Designed & developed an interactive web app for predicting kidney disease for a given patient using React.js, Node.js, PostgreSQL & a Desktop App for managing Real Time Clock (RTC) dongles using Electron.js, Python.

• Deployed an on premise server with custom configuration design, specifications and RAID configuration with firewalls and docker compose to deploy internal services like VCS, task manager etc on a Fedora Server which has improved productivity of developers in a lot of internal processes by 200%.

• Redefined the SDLC, improved software quality & accelerated development processes by introducing VCS with Gitlab, code reviews, automated CI/CD pipelines, better task management with Agile & Team Leadership

• Led the design and development of the Weather Automation project—automation of IoT devices (e.g., opening curtains & dimming lights in the morning) based on the weather of the customer's location (say sunrise, sunset, rainy or cloudy, etc.). We built this project using OpenWeather API, task scheduling using Bull with Redis, and microservices using Node.js to handle device actions & triggers.

• Devised a strategic solution to optimize system performance by 43% & remove deficiencies in the existing infrastructure, including APIs, database queries, response times, & server costs, by monitoring & collecting data using Newrelic.

• Maintained & added new features to a cross-platform hybrid application using Ionic with Angular for managing IoT devices, smart homes, automation, workflows, etc., which was licensed & sold to 100 businesses.

• Improved software quality and accelerated development processes by establishing coding standards and code reviews and implementing Agile methodologies such as Scrum, Continuous Integration, Continuous Deployment, & Continuous Testing pipelines, leading to enhanced productivity and higher-quality deliverables.

• Built an Order Management System (OMS) for FreshPrints to handle a million-dollar E-Commerce business with features like invoices, payments, refunds, orders, user management, etc. Developed using Angular, Node.js, MySQL & deployed on AWS (CloudFront, RDS, ECS, Fargate).

• Enhanced the sales by 23% and increased CPM by 20% by revamping the user interfaces and experience of funnels based on the user behavior and analytics from Mix panel and google analytics.

• Revamped the SEO by 59% & Google Page Speed Insights by 66% through initial page load optimizations, JS code minification, moved deployment to AWS CloudFront, updated cache policy, lazy loaded modules & compression.

• Drafted a CI/CD pipeline using BitBucket, Circle Ci and AWS ECS to deploy builds automatically to corresponding environments when all the tests pass on a commit with branching strategies.

• Dealt with complex business logic & transformed it into super-fast REST APIs in Node.js, optimized performance using caching with Redis, handled transaction failures, payment refunds & CRON jobs.
