Experience
- Associate Software EngineerResidue Solutions2025 to nowDuring my time as a Associate Software Engineer, I have been actively involved in designing, developing, and deploying scalable web applications while gaining strong hands-on experience with modern backend frameworks, cloud technologies, and deployment pipelines. Key contributions include: Calvary Center Church Donation Management System: Designed and implemented the backend using Express.js and MySQL, integrated with a React frontend. Containerized applications with Docker and deployed on AWS EC2. Configured Nginx for reverse proxy and implemented a CI/CD pipeline for seamless deployments. Gym Task Management System: Contributed to backend development using NestJS and MongoDB, and collaborated on the React frontend. Built real-time features using WebSockets (Socket.IO + NestJS). Deployed on AWS ECS, leveraging ECR for image storage, VPC for network security, and Load Balancer with Auto Scaling for high availability. Ensured secure connections with AWS Certificate Manager and Route 53, and implemented monitoring using CloudWatch. Gym Management System: Designed the backend with NestJS and integrated with Hikvision Fingerprint Access Manager through HikCentral Data Interchange. Implemented PostgreSQL Listen/Notify for real-time attendance marking and WebSocket-based live updates. Deployed on an AWS Lightsail Ubuntu instance, gaining hands-on experience with Linux-based environments. Through these projects, I have strengthened my expertise in cloud infrastructure (AWS), backend development (NestJS, Express.js), frontend integration (React), and modern DevOps practices (Docker, CI/CD, monitoring, scaling, and security).
