Abhay Pratap Singh

I’m a Java full-stack developer who enjoys turning complex workflows into reliable, high-performance systems. At HCLTech (Client: Avnet), I automated SAP data ingestion through ETL integration, eliminating manual Excel-based processes and cutting processing effort by 80% for 50K+ records per month.

I build complete features end to end—using Angular, Spring Boot, Hibernate, and MySQL to deliver REST APIs and improve data retrieval performance. I also optimize SQL queries and stored procedures with indexing and query tuning, reducing execution time by 45% across 100K+ records.

I’ve also worked on real-time and AI-driven products, from backend services in Elixir/Erlang with WebRTC and Phoenix Channels (reducing call setup latency by 35%) to WebSocket pipelines supporting 1,000+ concurrent connections. Earlier, I supported government-backed education platforms by building full-stack features with React Native and integrating 20+ REST APIs, plus WebSocket synchronization that reduced update latency by 60%—and I continue to carry that engineering discipline into projects like HealthTracker (Docker + REST-heavy Spring Boot) and my AI virtual therapist (Vertex AI, Firebase, Unity3D, Kotlin). I’m motivated by building pragmatic systems, clean architecture, and measurable impact—while learning fast through challenges and hackathons, including Google GenAI Hackathon and multiple university AI hackathon wins.
