Hi, I'm PraveenEngineer who enjoys designing solutions.
About me
With 3+ years of experience in the industry, I have spent my career automating infrastructure and building scalable applications for global industrial clients. I specialize in the intersection of Full-Stack development and DevOps meaning I don't just build features; I design the ecosystems they live in.
My journey is driven by a passion for innovation and entrepreneurship. I believe the best engineering solves real human problems. This belief led me to found and develop ventures like Pivisuma and Raddip, where I applied my technical skills to build products from the ground up
Wrapping up, I am a Pixel pusher by day, system slayer by night, always chasing the next epic refactor.âš¡

Projects
DevOps-Driven Acquisitions API for SaaS Marketplace
Built a production-ready Acquisitions API using Node.js, PostgreSQL (Neon DB), and Docker for buying/selling SaaS businesses. Implemented secure REST APIs with JWT authentication, role-based access (admin/user), and Drizzle ORM for type-safe queries. Used Arcjet for real-time bot/spam protection, Winston logging, Zod validation, and Kubernetes for scalable deployments with CI/CD pipelines and Jest/Supertest integration tests.
AI-Driven Proactive Autoscaling for Microservices
Final year research project focused on identifying the limitations of reactive, threshold-based Kubernetes autoscalers (HPA/VPA). Proposed and designed a proactive autoscaling framework using Transformer-based machine learning models for Kubernetes on Azure AKS. The system leverages Prometheus and Grafana for detailed observability and metrics collection, and includes an automated rollback mechanism to ensure safe and reliable scaling in production environments.
Raddip - Tech-Driven Traffic Solution
Developed Raddip, a ride-sharing mobile app designed to tackle Sri Lanka's urban traffic problems while encouraging sustainable transportation. The idea came from seeing how much time people waste sitting in traffic when they could be sharing rides with others going the same way.
Patient Management System
Built a microservices-based Patient Management System using Java, Spring Boot, and Docker. Implemented secure REST/gRPC APIs with bearer token authentication and PostgreSQL database. Used Kafka for event-driven communication and LocalStack to simulate AWS deployments. Configured API Gateway, load balancers, and wrote integration tests for service reliability.
