Experience

Research & Innovation Intern · HNNOIX India Private Limited

May 2026 – Jul 2026

Internship · Gurugram, Haryana · Hybrid

  • Worked on 6G research and development: network architectures, AI agents and communication systems.
  • Built reusable AI components (an LLM Gateway, a RAG Runtime, an AI Memory Layer and a Knowledge Base) for scalable agent execution, context management and workflow orchestration.
  • Applied generative AI, LLM, RAG and agent-based methods to decision-making, context-aware retrieval and workflow automation for 6G network architectures.

Freelance Financial AI Engineer · Quantitative Investment Analysis

Dec 2024 – Jun 2025

Freelance · Remote

  • Built 2 autonomous trading-signal systems with agentic AI and RAG that read market news, extract sentiment and emit structured signals in real time.
  • Cut false-positive trade signals by 37% with filtering rules and confidence scoring.
  • Built a CrewAI research pipeline on GPT-4, the Bloomberg API, Financial Modeling Prep and Alpha Vantage for automated earnings analysis.

Projects

CrohnSight · Medical computer vision

2026

0.992 AUROC, lesion vs normal (CrohnIPI). Reading a capsule-endoscopy study means checking tens of thousands of small-bowel frames by eye. An ensemble of 10 EfficientNet-B2 models (5 folds × 2 seeds) at the native 320 px finds lesions in 7 classes, grades severity in 4 tiers and draws a heat-map over each lesion.

Enterprise Agentic RAG Orchestrator · Multi-agent LLM system

2026

0.81 RAGAS faithfulness. Enterprise questions mix document lookups, database queries and actions such as sending email. A LangGraph Supervisor → Worker → Validator graph routes each query to Corrective RAG, NL-to-SQL, a human-in-the-loop email tool or chat.

OpenEnv Data-Cleaning Agent · Reinforcement learning environment

2026

0.967 PPO grader score on hard-clean. Cleaning a messy table takes many small, ordered decisions. An OpenEnv environment over pandas tables with reproducible (task, seed) episodes and a hidden clean ground truth.

Explainable Student Performance · MLOps + explainability

2026

9 models benchmarked, explained with SHAP + LIME. A model that predicts which students will struggle is only useful if teachers can see why it made each prediction. Pandera-validated data and a ColumnTransformer pipeline feed a benchmark of 9 models: linear, tree ensembles, XGBoost, CatBoost, LightGBM, a PyTorch MLP, a PyTorch LSTM and FLAML AutoML.

DCGAN Reproducibility+ · Generative vision research

2026

5 stability fixes over the 2015 paper, each documented. The 2015 DCGAN is famously unstable, and most re-implementations show only a grid of blurry samples, never what the networks learned inside. Keeps Radford et al.'s all-convolutional architecture but swaps in an LSGAN loss, Spectral Normalization, a Xavier/Kaiming initialisation, discriminator dropout and label smoothing.
