Backend AI Engineer Intern @ FlyRank • Java & Spring Boot Specialist • GenAI & RAG Practitioner
I am a Backend & AI Engineer who builds scalable, resilient, and intelligent systems that solve measurable real-world problems. My experience spans building enterprise-grade Java & Spring Boot backend microservices, coupled with modern Generative AI workflows (RAG, LangChain, Vector Search) and high-throughput FastAPI endpoints.
- 🏢 Industry Experience: Backend AI Engineer Intern at FlyRank — designed layered Spring MVC architectures, engineered secure RESTful microservices, and integrated enterprise LLM pipelines.
- 🌍 Real-World Impact: My AI-powered Career Guidance platform was selected by the UBA Group and deployed across rural schools in India to empower underserved students.
- 🧩 Algorithmic Discipline: 350+ DSA problems solved in Java using strict pattern-based problem solving (Sliding Window, Two Pointers, Binary Search, Dynamic Programming).

(15-min Polling) (3-Sigma Anomaly Z-Score) (JWT Auth + MySQL) (Glassmorphism KPI)
- Architecture: Engineered a production-ready decoupled architecture uniting Java 21 Spring Boot, Python FastAPI, MySQL, and a React 19 executive dashboard.
-
Real-Time Anomaly Detection: Ingests 15-minute telemetry across multi-zone facilities, establishes dynamic 24-hour diurnal seasonal baselines, and flags statistical anomalies (
$Z > 3.0$ ) in < 3 seconds. - Financial & Environmental Impact: Prevents equipment overloads in hospital campuses, targeting peak tariff bleed (₹11,500+/hr savings) and reducing carbon footprint with automated load-shedding playbooks.
