Hi, I am Shubhro Dev, a final-year Computer Science and Engineering undergraduate at the Rajiv Gandhi Institute of Petroleum Technology (RGIPT), an Institute of National Importance established along the lines of the IITs. I work at the intersection of large language models, multimodal deep learning, federated learning and time-series analysis, and I care most about building models that are not just accurate but also verifiable and privacy preserving.
I am currently a Technical Research Intern with the Global DAI R (SDE-IN) team at Siemens, researching the validation and verification of outputs generated by LLMs. Previously I worked as a research assistant and research intern at the VANET Lab (IIT Jodhpur), VCA Lab (IIT BHU Varanasi) and CMATER Lab (Jadavpur University), and as a data science / machine learning intern at Core-AI Solutions and Adani Power, across predictive maintenance, medical imaging and multimodal knowledge retrieval. I also placed at Global Rank 10 in the Meta Hacker Cup 2025 (AI Track).

Cross-Industry Privacy-Preserving Predictive Maintenance 聽
- Preprocessed the SCANIA-X dataset and engineered a hybrid architecture that combines numerical and categorical features of the dataset into transformer embeddings and a TabTransformer for least information loss. Also implemented various differential privacy (DP) algorithms (Spectral-DP, DP-SGD) to protect training data. Designed a global model architecture that would perform well for other PdM datasets that involve numerical, categorical, or any multimodal features in their datasets.
- Infused a Federated training approach based on the flwr library, allowing global model aggregation across heterogeneous clients having different computing power, parameters, and hyperparameters; mirroring real-life industrial equipment.
- Presently it is the best RUL prediction model on the dataset with an MSE of 2725 whilst keeping training data privacy. Developed an advanced MIA that considers white-box, gray-box, and black-box features, along with time-series specific seasonality/trend features; achieved a MIA success rate (AUC) of 49.12% and MIA accuracy of 49.59%, thus solidifying the claim.
- Implemented the DP mechanisms from scratch (including a Renyi Differential Privacy / Moments accountant) and a two-stage model pairing a Transformer time-series encoder with a TabTransformer head. This work is under review at IEEE T-ITS.
Context-Aware Multimodal Knowledge Retrieval 聽
- Built a context-aware parser to automatically extract and separately process multimodal content (images, tables, equations, graphs, text) and summarize each modality into vector embeddings. Employed modality-specific pipelines and selected appropriate LLMs per content type to improve summary quality; stored embeddings and summaries in ChromaDB using Hugging Face embeddings.
- Designed a multi-vector retrieval strategy that links document summaries to original content for improved context preservation. On query, the system retrieves relevant multimodal content and generates comprehensive, source-cited answers that reference text, table data, and image insights.
- Runs three parallel retrieval pipelines (LLM-summary embeddings, raw-atomic content, and CLIP text-to-image search), parsing documents with Docling and using Groq LLaMA 3.3 70B alongside Gemini 2.5 Flash Vision.
SENTRAL - Multi-Spectrum Stock Analysis 聽
- Conducted a fundamental analysis of target companies using 14 metrics (P/E, P/B, Debt, ROE, etc.) plus Piotroski F-Score and Altman Z-Score via custom functions. Executed technical analysis using 18 indicators (EMA20/50, SMA20/50, RSI14, MACD, ATR, etc.) and performed peer comparisons across sector companies.
- Collected news via seven APIs and web scraping, filtered items by relevance score, then fed the curated corpus to 10 LLMs (including finance-tuned and SOTA reasoning models) for sentiment extraction and signal generation. Visualized correlations and feature importance to support decision making.
- Applied Transformer and LSTM models to forecast price trends for reference and ensembled sentiment with fundamental and technical indicators to compute buy/hold/sell probabilities. Boosted newbie portfolio worth by +45% over five months.
- Packaged as two production-ready Streamlit apps (a deep single-stock analyzer and a screener.in-style screener) with a 20-strategy backtesting engine, Monte Carlo simulation and automated HTML/PDF report generation.
CodeGen - Autonomous Competitive Programming Solver 聽
- End-to-end autonomous solver (FastAPI + Google Gemini) built for the Meta Hacker Cup 2025 AI Track; the system behind my Global Rank 10 finish.
- Complete multimodal pipeline that fetches and decodes problem diagrams, generates a Python solution, and validates it against the sample I/O.
- Iterative self-repair feeds failures back to the model and regenerates up to four times; solved upper-medium-to-hard problems (~2200-2500 rating).
- Ships a reusable dev-kit with the prototype history and CP_GEN client tooling.
