Work Experience

Software Development Engineer Intern

Astute Systems Technology

Jan 2025 - Jan 2026 Indore
  • Architected and shipped scalable MERN Stack web applications with optimized RESTful APIs, MongoDB/MySQL schemas, and modular component design supporting high-concurrency user workflows.
  • Implemented end-to-end CI/CD pipelines using GitHub Actions, integrating automated testing frameworks that reduced deployment time and improved code quality across the release cycle.
  • Optimized backend service performance through query tuning, middleware refactoring, and caching strategies, contributing to measurable reductions in API latency and server load.

Full Stack / AI Intern

Astute Systems Technology

Jun 2024 - Aug 2024 Indore
  • Built a full-featured MERN Employee Management System with CRUD REST APIs and a responsive React.js UI, improving data handling efficiency by 30% over the previous workflow.
  • Refactored API architecture, eliminating redundant middleware and restructuring route handlers, cutting average API response time by ~25% and improving overall application scalability.

Projects

LLM Inference Logger — Production Observability Platform

PythonFastAPIReact/ViteSQLiteDockerKubernetesSSEPII Redaction
  • Architected a 3-service observability platform (React frontend, Fast API backend, dedicated Ingestion service) with multi-provider LLM support — OpenAI, Anthropic, Gemini, Deep Seek — and real-time SSE streaming to the browser.
  • Built a lightweight SDK wrapper capturing wall-clock latency (time, performance, counter), token counts, PII-redacted I/O previews, and UUIDs; shipped non-blocking via asyncio.create_task so LLM response time is never impacted.
  • Designed full Kubernetes manifests: namespace, Persistent Volume Claims, Secrets for API keys, Deployments with health probes & resource limits, and nginx Ingress with proxy-buffering disabled for SSE support.
  • Implemented request id deduplication in the ingestion service ensuring at-least-once delivery without double-counting; regex-based PII redaction covering emails, SSNs, card numbers, phone numbers, and secret key patterns.

HireMind AI — AI-Powered Resume & Interview SaaS

PythonFastAPIOpenAI APINLPReact.jsAWS Lambda/S3/DynamoDBJWTCI/CD
  • Designed end-to-end AI SaaS with resume parsing, ATS compatibility scoring, and JD matching using NLP (spaCy, TF-IDF) and semantic similarity algorithms achieving 90%+ matching accuracy.
  • Architected serverless AWS backend (Lambda + API Gateway + S3 + DynamoDB) with RBAC, JWT authentication, and GitHub Actions CI/CD — reducing simulated HR screening time by 60%.
  • Developed AI Interview Question Generator via OpenAI API producing role-specific, difficulty-calibrated technical and behavioral questions derived from parsed JD and resume context.

AI Health Monitoring & Disease Prediction System

PythonOpenAI WhisperNLPScikit-learnXGBoostFastAPIRandom ForestSVM
  • Engineered an AI-powered health monitoring system capturing real-time voice input via OpenAI Whisper, processing through custom NLP pipelines, and predicting diseases from symptom analysis with high precision.
  • Built and fine-tuned ensemble ML models (Random Forest, SVM, XGBoost Voting Classifier) with NLP-based feature engineering; developed scalable FastAPI REST endpoints for real-time model inference.

Expert Management System — Travel & Tourism Platform

MERN StackAI Recommendation EngineJWTRBACREST APIsMongoDB
  • Developed a MakeMyTrip-like full-stack MERN platform with an AI-driven recommendation engine personalizing hotel, flight, and train suggestions based on user preferences and travel history.
  • Implemented JWT-based authentication, Role-Based Access Control (Admin/Employee/Customer), and optimized MongoDB queries handling concurrent booking workflows with consistent performance under load.
