Gurugram

• Architecting a Generative AI HR Assistant (FastAPI, LangChain/LangGraph, Google Gemini, Pinecone, Next.js/TypeScript, SQLite, Docker), adapting the hybrid retrieval and multi-tier LLM fallback design from OmniRAG (see Projects). Currently in beta testing with 2-3 employees to automate onboarding, policy compliance training, and HR support for small businesses without a dedicated HR team • Building a standalone HR Analytics platform with XGBoost and deep learning models, using class weighted training and ensemble stack- ing to handle severe class imbalance in rare event prediction. Trained on a manually labeled dataset of 1,500 employees across 5-8 features (overtime hours, monthly income, job satisfaction, absenteeism, tenure) to flag flight risk, burnout risk, and upskilling needs, reaching 60-70% validation accuracy so far with the dataset still growing • Driving both workstreams independently as a fresher hire, handling dataset labeling, feature engineering, and system architecture end to end, within a 5-person tech team reporting directly to the CEO

• Architected and delivered a full-stack background verification ERP from scratch (Node.js, Express.js, MongoDB Atlas, Vanilla JS), engineering scalable document ingestion and pipeline orchestration workflows that scaled operations from 4–5 to 30–40 verifications per month • Engineered a multi-layered security architecture comprising custom payload encryption middleware, JWT session authentication, bcrypt password hashing, IP surveillance, and automated session cleanup, enforcing zero-trust request validation, strict access control, and real-time network traffic monitoring across all admin endpoints • Designed a cloud-native document ingestion and retrieval pipeline (Google Cloud Storage + Multer) for heterogeneous document types — identity proofs, certificates, and academic records, improving traceability and maintaining end-to-end integrity across GCS and MongoDB Atlas storage layers

Pilani

• Built PyTorch inference module and telemetry data preprocessing pipeline for weather-adaptive ML/DL drone flight stabilization system, fine-tuning on ∼50 hr flight telemetry for edge deployment on onboard compute, achieving 80% stability improvement over standard PID baseline in crosswinds above 10–15 m/s • Developed 3D product demo platform (Angular, Three.js, GLTF/GLB, GSAP, Node.js, MongoDB) to simulate hybrid VTOL mechanics and flight modes with semantic, interactive visualization, adopted as company’s primary investor-facing interface • Reverse-engineered the QGroundControl (QGC) C++/QML codebase and ported it to a Java backend and JavaScript web client with WebSocket-based command and telemetry flows, enabling browser-based control for custom drone hardware
May 20243 mosJul 2024

Pune District

• Architected a 0-72hr probabilistic rainfall & hazard prediction system stacking LSTM/Transformer architectures (PyTorch) with LightGBM/XGBoost and fusing multi-source data pipelines (IMD API, OGIMET SYNOP/METAR, MOSDAC, ERA5, ECMWF/GFS GRIB2), applying Non-homogeneous Gaussian Regression (NGR) post-processing and isotonic regression calibration to address severe class imbalance in rare-event prediction, achieving 70–80% forecast accuracy at 72-hour lead time across 5 meteorological parameters with uncertainty aware, class-weighted training for rare events including heatwaves and cold waves • Engineered an 18-component Apache Airflow-orchestrated data pipeline handling live multi-source ingestion (IMD API, OGIMET SYNOP/METAR, MOSDAC, ERA5, ECMWF/GFS GRIB2, NetCDF4), quality control and gap-filling using Python, xarray, GeoPandas, rasterio, and R, followed by NWP refinement and ensemble model output generation, establishing the feature engineering and ingestion architecture for downstream probabilistic ensemble modeling • Identified a critical gap in IMD’s manual forecast verification workflow and engineered a full-stack Forecast Verification Portal (vanilla JS + PHP) that fed scientist-verified forecasts back into pipeline for continuous model fine-tuning, reducing scientists’ manual verification effort by 80% and executing 8 automated forecast cycles daily

About

I am a dual degree graduate from 𝐁𝐈𝐓𝐒 𝐏𝐢𝐥𝐚𝐧𝐢 and 𝐈𝐈𝐓 𝐌𝐚𝐝𝐫𝐚𝐬, with 𝟑+ 𝐲𝐞𝐚𝐫𝐬 of hands on experience building agentic systems, evaluation pipelines, and production AI/ML systems across freelance work, startups, and a Government of India research lab, owning projects end to end. My core strength is taking a system from a rough idea to something that actually holds up in production, a skill built through owning systems end to end rather than just contributing. Highlights, 1. 𝐈𝐌𝐃, 𝐆𝐨𝐯𝐞𝐫𝐧𝐦𝐞𝐧𝐭 𝐨𝐟 𝐈𝐧𝐝𝐢𝐚 𝐫𝐞𝐬𝐞𝐚𝐫𝐜𝐡 𝐥𝐚𝐛: Built 0-72hr weather prediction system stacking LSTM, Transformer, LightGBM and XGBoost. 2. 𝐕𝐢𝐦𝐚𝐧𝐚, 𝐝𝐫𝐨𝐧𝐞 𝐬𝐲𝐬𝐭𝐞𝐦𝐬 𝐬𝐭𝐚𝐫𝐭𝐮𝐩: Owned PyTorch inference module for weather adaptive flight stabilization, improving stability by 80% in strong crosswinds, and reverse engineered QGroundControl codebase, porting to JavaScript stack for browser based drone control. 3. 𝐁𝐥𝐮𝐞𝐨𝐜𝐞𝐚𝐧, 𝐛𝐚𝐜𝐤𝐞𝐧𝐝 𝐚𝐧𝐝 𝐬𝐞𝐜𝐮𝐫𝐢𝐭𝐲: Architected full stack background verification ERP with multi layered security including custom encryption and JWT auth. 4. 𝐎𝐮𝐭𝐥𝐢𝐞𝐫 𝐚𝐧𝐝 𝐎𝐩𝐞𝐧𝐂𝐥𝐚𝐰, 𝐟𝐫𝐞𝐞𝐥𝐚𝐧𝐜𝐞 𝐋𝐋𝐌 𝐰𝐨𝐫𝐤: Frontier LLM evaluation and alignment work, RLHF-style annotation, red-teaming across general-purpose models, 4 custom tool-use agents built and 15+ agents red-teamed against OWASP Top 10 for LLM Applications categories. 5. 𝐁𝐥𝐮𝐞𝐨𝐜𝐞𝐚𝐧, 𝐌𝐋 𝐄𝐧𝐠𝐢𝐧𝐞𝐞𝐫 𝐚𝐧𝐝 𝐆𝐞𝐧𝐀𝐈 𝐃𝐞𝐯𝐞𝐥𝐨𝐩𝐞𝐫: Architecting Generative AI HR Assistant, adapting the hybrid retrieval and multi-tier LLM fallback design from OmniRAG project into production, alongside HR Analytics platform using XGBoost and deep learning to flag flight-risk and burnout signals. My toolkit includes Python, PyTorch, LightGBM, XGBoost, HuggingFace Transformers, ONNX Runtime, Airflow, MLflow, FastAPI, Node.js, Docker, Redis, LangChain, RAG pipelines, YOLOv11, ViT, EfficientNet, C++17, Linux, and Git. I am open to full time roles in India and remote roles globally. I am targeting Applied ML, MLOps, GenAI Engineering, and Computer Vision roles.
