Staff / Principal Frontend Engineer | Technical Lead

I set frontend technical direction and architecture standards for a six-engineer team building five enterprise EV-charging and business-operations platforms: EVES, DynaChrg, PayU, XSM, and XSI.

I architected scalable UI frameworks with role-based access control and automated testing pipelines. I established coding standards and a shared component library/design system used by three teams, reducing bugs by 30%, and implemented CI/CD improvements that increased delivery efficiency by 25%.

I also define technical roadmaps, champion Atomic Design and reusable primitives, conduct code reviews, and mentor engineers to strengthen technical quality and collaboration.

I designed and implemented scalable POS transaction microservices using CQRS and Event Sourcing to support thousands of transactions per day with improved reliability and maintainability.

I built serverless AWS architectures using ECS, Lambda, and DynamoDB, reducing infrastructure costs by 25%. I used TypeScript, Jest, and domain-driven design principles to improve transaction throughput and system resilience.

I also led cross-functional adoption of Agile practices to improve delivery speed and team collaboration.

I led development of HRM modules for performance appraisals and advanced reporting, improving HR efficiency by 30%.

I re-architected seller dashboards and rental-listing workflows into reusable, componentized React modules used by thousands of monthly users. This improved engagement, usability, and long-term maintainability.

I collaborated with backend teams on Node.js and MySQL API architecture, reducing response times by 25% while delivering frontend solutions aligned with business needs.

I designed and launched a scalable ERP and LMS platform with encrypted attendance tracking and real-time collaboration capabilities.

I built the platform using React, Node.js, AWS Lambda, S3, DynamoDB, microservices, and serverless architecture to support high availability.

I integrated Google Meet APIs for online classrooms capable of supporting more than 5,000 concurrent users.

I developed a SaaS platform for health blogs, appointment scheduling, and medical tools to improve user engagement.

I implemented React server-side rendering for SEO and built Node.js and MySQL APIs for scalable backend operations. I also applied React performance tuning and advanced patterns.

These improvements increased site speed by 35% and user retention by 25%.

I designed CRM dashboards, e-commerce platforms, and service websites with scalable and maintainable architectures.

I managed end-to-end AWS deployments and server operations, ensuring high availability and optimized application performance.

I also served as a Technical Architect, consulting with clients on requirements and overseeing implementation delivery.
