Ridham Taneja

AI/ML Engineer β€’ Python Developer β€’ B.Tech CSE (AI/ML) Graduate



B.Tech CSE (AI/ML) graduate building end-to-end AI systems β€” from deep learning models to deployed, multi-service full-stack products.


About Me

  • B.Tech CSE (AI/ML) graduate (2026), focused on shipping real deployed systems over pure theory
  • Built and deployed 6 end-to-end AI/ML projects β€” from a CNN+BiLSTM+Attention fraud detector to a full-stack job tracker with a Chrome extension
  • Comfortable across the full stack: model training β†’ FastAPI backend β†’ React/Streamlit frontend β†’ cloud deployment
  • Interested in Deep Learning, RAG/multi-agent systems, and production ML infrastructure
  • Open to AI/ML Engineering and Full-Stack roles β€” actively interviewing

Featured Projects

1. 🚨 UPI Sentinel β€” Contextual Fraud Detection

Sequence-based fraud detection that analyzes transaction behavior over time instead of scoring transactions in isolation. A CNN β†’ BiLSTM β†’ Attention pipeline flags account-draining patterns that look harmless individually but suspicious as a sequence.

Result: Precision 0.91 Β· Recall 0.77 Β· F1 0.83 Β· ROC-AUC 0.99 (highly imbalanced data) Β· real-time FastAPI inference + Streamlit monitoring dashboard

2. 🏨 GuestFlow AI β€” Multi-Agent Hospitality Automation

Event-driven hotel workflow platform that routes guest requests through pre-stay, in-stay, and post-stay agents, with a RAG-powered hotel FAQ assistant running on a local LLM (Ollama + Phi-3). Handles the full ticket lifecycle with auto follow-up and stale-ticket escalation, VIP prioritization from real guest profiles, policy-compliant review collection (no review-gating), and proactive owner analytics that surface recurring issues before they escalate β€” plus a daily manager digest email.

3. πŸ“‹ ApplyBoard β€” Job Application Tracker (Flagship)

A full-stack tracker for job-hunting freshers juggling 50+ applications across platforms. One-click capture via a Chrome extension (auto-fills from LinkedIn, Naukri, Internshala, Indeed), a React pipeline dashboard, Google OAuth, and PWA support for mobile.

4. πŸ† Redrob Candidate Ranker

A five-layer, rule-based candidate ranking pipeline that filters 100,000 profiles down to a top-100 shortlist with per-candidate reasoning β€” no LLM, no black box, fully explainable, under 5 minutes on CPU. Built for the Redrob India Runs Data & AI Challenge.

5. 🌍 CarbonLens

An awareness-first carbon footprint app β€” one short form instead of daily logging, real sourced emission factors (not made-up multipliers), and results explained through relatable comparisons rather than a guilt-driven number. Optional Claude-personalized reduction tips with a rule-based fallback. Scored 92.2/100 in Hack2Skill's PromptWars AI evaluation.

6. πŸš€ IPO Sentinel β€” Listing Gain Prediction

Predicts whether an IPO will deliver >10% listing gains using only pre-listing, publicly available data β€” strict no-leakage discipline, no Grey Market Premium. Trained on Indian mainboard IPOs (2010–2025); seven models benchmarked, with CatBoost coming out on top.

Result: ROC-AUC ~0.927 (best) Β· 0.90–0.93 across all 7 models
