## 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\.

## Work experience

ML Engineer and GenAI Developer at Blueocean International India Pvt\. Ltd\., Feb 2026 \- Present · 7 mos, 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

AI/ML Engineer at Outlier \- OpenClaw Project, Oct 2025 \- Jan 2026 · 3 mo, Remote, • Delivered RLHF\-style human feedback annotation, red\-teaming, and rubric\-based evaluation across general\-purpose LLMs on Outlier \(including the OpenClaw project\), sustaining 10\-15 tasks/cycle at 70\+ hrs/week with a greater than 90% acceptance rate • Created 4 custom tool\-use/function\-calling and multi\-step reasoning agents and red\-teamed 15\+ agents within simulated multi\-step task environments \(synthetic SQL databases, mock APIs\), achieving a 100% break rate by exploiting incorrect tool selection, malformed function arguments, and multi\-step plan derailment; findings mapped to OWASP Top 10 for LLM Applications categories including prompt injection, hallucination under ambiguity, tool\-misuse, and context\-window exploitation • Authored 15\+ evaluation rubrics from scratch and conducted 40\+ individual model evaluations across structured 3\-5 LLM head\-to\-head comparison studies \(including Claude and OpenAI models\), benchmarking outputs against authored rubrics across reasoning, safety, and task\-completion dimensions

Backend \(Full\-Stack\) and Security Engineer Intern at Blueocean International India Pvt\. Ltd\., Mar 2025 \- Oct 2025 · 8 mos, Gurugram, • 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
