⚡ About Me

CSE undergraduate at GITAM University, Visakhapatnam (CGPA 9.17), focused on Data Engineering and Backend Systems. I would rather build a pipeline that survives bad input at 3am than tune a model for another half a point of accuracy.

🏢  Software Engineering Intern at Motherson Technology Services Limited (AIML Team), where I independently designed and shipped the chat-history persistence layer for LegalLens, a live AI legal-research platform — a 316-line FastAPI module, 9 CRUD endpoints, and a hybrid SQLite + Azure Blob Storage architecture, across a full-stack React/TypeScript + Python codebase.

🎓  IBM Data Engineering Professional Certificate — 16 courses covering Airflow, Kafka, Spark, Hadoop, data warehousing, NoSQL and BI.

🚩  Domain Lead, Open Source & DevX — GitHub Community, GITAM Vizag.

🔭  Currently working on

  • Airflow DAG orchestration, star-schema design and incremental ETL patterns
  • Deepening FastAPI, PostgreSQL and cloud-storage architecture
  • V Semester: Data Warehousing & Mining, Computer Networks, Machine Learning Techniques

💬  Ask me about ETL design, schema normalization, or why your pipeline is silently dropping rows.

🚀 Featured Projects

🛡️ Fake Account & Threat Detection Engine

Python XGBoost SHAP FastAPI React NetworkX

Intelligence-grade detection engine for ITBP / Ministry of Home Affairs, built for Smart India Hackathon.

  • Dual platform-specific XGBoost classifiers on 101,000+ labeled accounts — 90.04% accuracy on X, 96.87% on Meta
  • Diagnosed a mislabeled 50,000-row dataset silently capping accuracy at 67%; bifurcated feature pipelines lifted it 23 points
  • SHAP explainability surfaced as plain-English risk factors
  • Playwright live scraping with zero credential storage, NetworkX coordinated-behaviour graph, one-click forensic PDF exports

🏦 Global Banking Data ETL Pipeline

Python Pandas NumPy SQL

Fault-tolerant, multi-source ETL pipeline feeding a unified SQL warehouse.

  • 30% less data redundancy via automated schema normalization and vectorized outlier detection
  • Incremental delta loads replacing full batch refreshes, eliminating redundant reprocessing
  • Structured logging and alerting that intercepts schema mismatches before load — no silent corruption reaches the warehouse
  • Strict type validation enforced at the transformation stage

🏥 KAPS MedTech — Healthcare Management

PostgreSQL Node.js Raw SQL JWT BCrypt

Built in 24 hours at Gitathon University Hackathon.

  • 3NF-compliant schema modelling many-to-many relationships across patients, doctors and appointment slots
  • Real-time smart-inventory module that auto-quarantines expired medication, replacing a manual audit
  • PHI secured with BCrypt hashing and stateless JWT auth
  • One-command deployment — init_db.js cuts environment setup to under 30 seconds

✈️ TripSync — AI Travel Platform

TypeScript MongoDB React Gemini API Mapbox

Smart India Hackathon 2025 qualifier, prototype from zero in 24 hours.

  • Node.js/Express backend supporting multiple concurrent users
  • Geospatial pipeline over Mapbox and Google Maps for multi-stop routes with real-time waypoint prediction
  • Led a full-stack TypeScript migration with strict type enforcement, closing a whole class of runtime errors

⚙️ High-Performance Autocomplete Engine  ·  C Make Valgrind GDB

Low-latency autocomplete backend in C — O(k) lookup via a Trie regardless of dataset size, Min-Heap priority queue ranking Top-N terms in O(log N), zero memory leaks verified under Valgrind, and a binary serialization protocol for sub-second cold starts.

🎃 Open Source @ GITAM  ·  terminal-arcade  ·  open-source-launchpad

As Domain Lead, I build the repositories our community learns to contribute on — beginner-friendly issues, CI that explains its failures, and automation that assigns issues so nobody sits blocked.
