Develop and maintain scalable EV charging platforms using Golang for backend services and React.js for frontend applications, implement real-time charger communication via OCPP (WebSocket), enable roaming and interoperability through OCPI integrations, design real-time monitoring dashboards for charger status, sessions, and system health, and collaborate cross-functionally to deliver reliable, high-performance EV charging solutions.

Designed and maintained internal platforms to optimize operational efficiency, including a web application for pricing data management, an inventory system for warehouse stock control, and a CRM with AR/AP functionality and customer segmentation. Developed a PWA for field technicians to streamline daily tasks and rewrote a Node.js codebase in Golang to enhance scalability. Built automation tools, such as a Slack bot for managing Vault (HashiCorp) access and a provisioning system for GSuite, Slack, Vault, VPN, Jira, Confluence, Bitbucket, and internal tools to automate employee onboarding and offboarding.

Developed a dashboard management system by collaborating with backend engineers to create efficient and scalable services for Angular. Worked closely with UI designers to build clean and reusable UI components, and with product engineers to investigate and resolve issues. Assisted QA engineers in debugging and fixing defects, ensuring a seamless user experience. Additionally, analyzed and reviewed feature performance for optimization and rewrote the application to align with a new backend and UI design.

Developed web applications, including dashboard management systems, e-commerce platforms, and web forms. Built backend environments using API Gateway, AWS Lambda, and third-party API integrations, and designed database schemas with AWS Amplify and AWS SAM. Collaborated with designers to create clean and efficient UI components, implemented state management services in Angular, and investigated errors to reproduce and resolve issues. Additionally, developed an AWS Cognito library for Angular 7+.

The role involved operating resin potting machines for ECU 2W production, ensuring precision and efficiency in the manufacturing process. Responsibilities also included product repair and performing daily routine machine checks to maintain optimal production quality and minimize downtime.

I involved developing product prototypes, including designing PCBs using Protel 99, soldering electronic components, and researching sensor technologies. A key project was the Smart Galon, which focused on developing a capacitive sensor for improved water level detection. This role provided hands-on experience in IoT hardware development and embedded systems.
