πŸ‘‹ Hi, I'm Ashruj Gautam

πŸŽ“ Master's in CS @ University at Buffalo Β Β |Β Β  πŸ€– AI/ML Enthusiast & SWE Explorer
πŸ”— Email β€’ LinkedIn

I build intelligent systems β€” from scientific RAG pipelines to medical diagnostics,
and love turning deep learning + Software engineering into real-world applications.


🧠 About Me

  • πŸš€ I enjoy building production-grade AI systems and developer-focused tools with measurable real-world impact
  • πŸ’‘ Passionate about the intersection of LLMs, RAG, multimodal learning, and software engineering
  • 🧰 Equally confident in training deep models or scaling fast APIs and databases
  • πŸ’Ό Open to roles in: AI/ML Engineering, Fullstack Development, Software Engineering, and Applied Research

πŸš€ Highlighted Projects

πŸ”¬ HireSphere

Built a full-stack job search management platform with AI-driven resume analysis (Llama 3.3 70B via Groq), ATS optimization, keyword gap detection, and a Chrome Extension to clip job listings directly from LinkedIn and Indeed.

  • πŸ’‘ Built with FastAPI, React, PostgreSQL, and Llama 3.3 70B via Groq API
  • πŸ”— Includes a Chrome Extension (Manifest V3) for one-click job clipping from LinkedIn & Indeed
  • πŸ“Š AI analysis delivers match scores, missing keywords, ATS tips, and a rewritten resume summary

Built a high-performance URL shortening service with single-digit millisecond redirects, async click analytics, and geo/device parsing β€” engineered to handle massive traffic without blocking the Node.js event loop.

  • πŸ’‘ Built with Node.js, Express, PostgreSQL, Redis, BullMQ, and React (Vite + Tailwind)
  • ⚑ Decoupled redirect and analytics paths using a fire-and-forget BullMQ worker queue for non-blocking, high-volume click tracking.
  • πŸ› οΈ Conquered real-world engineering challenges, including cache data mismatches, BullMQ connection clashes, and aggressive browser caching.

Built an advanced Retrieval-Augmented Generation system for scientific PDFs β€” integrating section classification, citation graph analytics, figure detection, and local LLM generation (Mistral 7B).

  • πŸ’‘ Used Grobid, LayoutLM, ChromaDB, and fine-tuned BERT
  • πŸ”— Full hybrid vector + keyword retrieval system with prompt optimization
  • πŸ“š F1 Score: 99.54% (Reference Parsing), 79.94% (Section Classification)

AI diagnostic system combining X-ray imaging, clinical NLP, and tabular risk analytics into a unified medical assistant with prescription guidance.

  • 🩻 DenseNet121 (CheXpert) + BioBERT + MLP Ensemble (Kidney, Heart, Diabetes)
  • πŸ€– Integrated with LLaMA for contextual recommendations
  • πŸ’» Packaged with PyQt5 GUI and local data fusion

Production-grade PostgreSQL analytics engine with stored procedures, triggers, indexing, and planned LLM augmentation for feedback analysis.

  • 🧠 11+ table schema, optimized queries, and stored functions in PL/pgSQL
  • πŸ“ˆ Real-time business metrics: customer behavior, delays, seller ranks
  • 🧠 Extending with Zephyr LLM to auto-summarize trends & complaints

Custom YOLO variant optimized for occluded fruit detection in retail scenarios. Compared performance against SSD, Faster R-CNN.

  • πŸ–ΌοΈ Trained on MinneApple + COCO with resolution-aware tuning
  • πŸš€ Real-time object detection via optimized bounding box anchors

Built a semantic image search engine that lets users query with text or images and returns top-matching results using precomputed embeddings.

  • 🧠 Uses OpenAI CLIP + FAISS for vector similarity
  • πŸ–ΌοΈ Visual & text-to-image search in real-time
