Hi, I'mGautam Kumar
Full-Stack Developer with a Microsoft Elevate internship. I build AI-integrated SaaS products using React, Node.js & TypeScript — from deepfake detectors to LaTeX resume builders.
Where I've Worked
3 production internships building real-world products.
Microsoft Elevate × AICTE
Emerging Technologies Intern
- Built Satark-AI, a deepfake detection platform using Microsoft Azure, FastAPI, PyTorch, and SpeechBrain as the capstone project.
- Designed a 3-tier microservice architecture and deployed an AI-powered audio forensics engine processing MFCC/Spectral analysis for real-time threat detection.
Edunet Foundation (AICTE × IBM SkillsBuild)
Frontend Web Development Intern
- Engineered responsive UIs using HTML5, CSS3, JavaScript, achieving a 95+ Lighthouse score and 100% cross-browser compatibility.
- Optimized frontend asset loading, resulting in a 30% reduction in initial page load time.
YHills
Full-Stack Web Development Intern
- Developed a scalable full-stack application using the MERN Stack, architecting RESTful APIs for seamless client-server data flow.
- Built dynamic frontend components using React.js, improving user engagement by 25%.
Things I've Built
Production-grade SaaS products with AI integration.

AI-Powered Mock Interview Platform
A Production-grade AI Mock Interview Platform with 91 features across 18 phases. Features AI-powered interviews via Groq Llama 3.3-70b, real-time ML video proctoring (face-api.js with TensorFlow.js), CRDT collaborative code editor with three-way merge, WebRTC video calls with STUN/TURN + SFU, sandboxed code execution via Piston API, and multimodal voice tone analysis. Built as a Turborepo monorepo with 81 service modules, 38 route files, and 7 MongoDB models.

Deepfake Audio Detection & Voice Verification
A production-grade deepfake detection platform built as a Turborepo microservices monorepo. Detects synthetic audio via Wav2Vec2 + MFCC spectral forensics, deepfake images via Hugging Face Inference API (face deepfake + AI-image detectors) through a Cloudflare Worker proxy, and verifies speaker identity using ECAPA-TDNN voice biometrics with 192-dim embeddings and cosine similarity matching. Ships as a PWA with real-time microphone monitoring, analytics dashboard, and PDF report exports.

Premium AI-Powered LaTeX Resume Builder
A modern SaaS that combines real LaTeX PDF rendering with LLM intelligence. Features a LangGraph multi-agent resume coach (ATS scoring), LinkedIn PDF import via Llama 3.3, FAANG-ready templates, drag-and-drop editor, Organizations with RBAC (Owner → Admin → Editor → Viewer), BullMQ async PDF generation with progress tracking, distributed Redis rate limiting, Razorpay payments, and GDPR compliance (data export + PII anonymization).

Hyper-Local Food Delivery PWA
A production-grade multi-vendor food delivery platform with 4-role ecosystem (Admin, Restaurant, Delivery, Customer). Features AI chatbot (Groq LLM) for food recommendations, voice search in English & Hindi, biometric auth (WebAuthn fingerprint/FaceID), real-time GPS delivery tracking via Socket.io, Razorpay payments (UPI/Cards/Wallets/COD), gamification (streaks, SwadCoins, badges), group ordering with bill splitting, and PWA with offline support. Built with 30+ API routes, 14 Mongoose schemas, and enterprise security (fraud detection, rate limiting, GDPR).

Who I Am
I'm a Computer Science student from Sitamarhi, Bihar, currently based in Jaipur, Rajasthan at Jagannath University, and a Full-Stack Developer passionate about building products that make a real impact.
With a Microsoft Elevate internship and 3 production internships under my belt, I've built and deployed AI-integrated SaaS products — from deepfake detection systems to AI-powered mock interview platforms.
I thrive at the intersection of AI/ML and Full-Stack Development, using technologies like React, Node.js, Python, LLMs (Llama 3, LangGraph), and DevOps tools (Docker, TurboRepo) to build scalable, real-time systems.
