About

Professional summary

I am a Senior Full Stack Engineer with more than 10 years of experience building scalable SaaS platforms, high-performance web applications, and cloud-native systems. My primary expertise spans React, Next.js, Angular, TypeScript, .NET Core, FastAPI, and Node.js.

I specialize in end-to-end architecture and delivery of multi-tenant applications, secure REST APIs, distributed systems, and role-based access control solutions. I have owned projects from technical design through production deployment and ongoing optimization.

I have modernized enterprise applications by migrating legacy frontend systems to React, Next.js, and Angular. My work includes building responsive dashboards, commerce experiences, learning platforms, HRMS products, analytics applications, and investment platforms.

I am experienced with Azure-based CI/CD workflows, relational and NoSQL databases, application security remediation, performance tuning, and third-party integrations such as payment gateways, Firebase, and SendGrid. I focus on reliable, maintainable systems that scale.

I actively use AI-augmented engineering tools including ChatGPT, Claude, GitHub Copilot, and Lovable to improve development speed, debugging, code quality, and delivery outcomes. I also enjoy leading technical decisions, mentoring engineers, and collaborating across product, DevOps, and leadership teams.

Career history

Full Stack Engineer Codemetrics Infotech Pvt. Ltd.

I own the end-to-end architecture and development of a cloud-ready multi-tenant HRMS SaaS platform for managing employee lifecycles, organizational hierarchy, leave policies, evaluations, and secure access control.

I architected isolated multi-organization data handling, built a high-performance Next.js and TypeScript frontend, designed scalable REST APIs and relational schemas, and implemented subscription billing with payment gateway integration. I strengthened security through RBAC, helped establish CI/CD pipelines, and used AI tools for development, debugging, and optimization.

Full Stack Developer Informa Systems

I worked on InformaOne, an enterprise learning, records, and compliance management platform for public safety agencies. The system supports training, certification, scheduling, assessments, role-based access, and reporting workflows.

I led a cross-functional Angular and .NET Core team, developed responsive interfaces for dashboards, scheduling, and assessments, and built secure REST APIs for records, certification, and reporting. My optimization work reduced UI load times by approximately 30–40% and backend latency by approximately 25%, while I also mentored engineers on architecture, code quality, and CI/CD practices.

Full Stack Engineer Danfoss

I contributed to the Danfoss Turbocor OEM portal, a secure support and resource platform used by OEM partners and service technicians to access product literature, manuals, service tools, certifications, and technical documentation.

I migrated and optimized the frontend using React and Next.js, implemented security fixes identified by Black Duck and Polaris scans, and maintained backend integrations through Umbraco CMS.

Full Stack Engineer Merkle

I worked on George.com, a high-traffic fashion and lifestyle e-commerce platform focused on frontend modernization, performance, and scalable commerce capabilities backed by Salesforce Commerce Cloud.

I developed responsive, modular React and TypeScript UI components and contributed to product catalog, search filtering, cart and checkout, and account-management functionality. I integrated frontend features with SFCC APIs, managed application state across customer journeys, and improved performance, accessibility, and cross-browser consistency.

Full Stack Engineer Royston

I worked on Enginei, a data-driven marine energy and performance management platform that helps vessel operators monitor fuel consumption, energy efficiency, tank and bunker management, and voyage performance using real-time sensor, GPS, and telemetry data.

I built high-performance analytics dashboards with React and Angular, improving report rendering speed by up to 40%. I also designed scalable .NET Core REST services and led frontend and backend performance tuning initiatives to reduce latency and improve responsiveness.

Project Team Lead Softmind Infotech Pvt. Ltd.

I worked on iFlip Invest, an AI-powered investment platform for automated stock and ETF portfolio management. The platform used machine-learning-driven SmartFolios and proprietary algorithms to support portfolio strategy, performance monitoring, and investment workflows.

I developed responsive investment dashboards and portfolio analytics with React, Redux, and Tailwind CSS. I built SmartFolio selection and real-time visualization components, integrated frontend functionality with REST APIs for portfolio updates and recommendations, and improved page-load and interaction performance.
