Bandra: about Shaun

Home station · Fr. CRCE, Bandra.

Hi, I'm Shaun.

AI engineer. Bandra is home.

I'm a Computer Engineering graduate from Fr. CRCE, Mumbai, and an AI engineer with internship experience across AI engineering, research, data engineering and product development.

I've built agentic systems, RAG pipelines, voice AI and developer tools, most recently at Siemens Digital Industries Software.

Outside work I ship my own products, compete in national hackathons, and like to be part of everything: I joined GDSC as a web developer and ended up leading it.

  1. WINDOW 1/4

    The conversational copilot (MCP)

    Problem
    Complex version-control operations were buried behind menu-driven workflows.
    What I built
    A conversational interface that replaced those menus, exposed both to the application UI and to external AI-enabled IDEs.
    How
    An MCP server over a Spring Boot/gRPC backend that auto-generates LLM-discoverable tools from OpenAPI specs.

    Illustrative example; not the real tool names.

    What changed between the last two releases? Open a merge for the fixes.
    • ✓ openapi → tool: get_branch_history
    • ✓ openapi → tool: compare_versions
    • ✓ openapi → tool: create_merge_request
    Done. 12 changes between the two releases; merge request opened.
  2. WINDOW 2/4

    Tool discovery at scale

    Problem
    Sending 100+ candidate tools to the LLM on every request is slow and expensive.
    What I built
    Hybrid intent routing plus semantic tool filtering that narrows 100+ candidate tools to 3–8 per request.
    How
    A 384-dimension sentence-transformer embeds requests and tools; cut LLM API costs by ~75% while reducing inference load.
    • sentence-transformers
    • embeddings
    • intent routing
    100+ TOOLS → 3–8 PER REQUEST
    LLM API COST100%

    Animation: over a hundred candidate tools are filtered down to between three and eight per request; LLM API cost falls by about 75 percent.

  3. WINDOW 3/4

    AI defect investigation

    Problem
    Developers started every defect from scratch across 8 interdependent repositories.
    What I built
    An automated pipeline that fetches Jira issues, resolves ambiguous component mappings and orchestrates AI-assisted root-cause analysis. It produces structured triage reports (suspect commits, impacted files, fix recommendations, test strategies) and auto-publishes them back to Jira. Now in regular team use.
    How
    GitHub Copilot and Siemens-hosted LLMs, orchestrated in Python, so developers start from a pre-investigated issue.
    • Jira
    • GitHub Copilot
    • LLMs

    • Suspect commits

    • Fix recommendations
    • Test strategy
  4. WINDOW 4/4

    Production engineering

    Problem
    Testing and packaging were manual.
    What I built
    A 3-stage GitLab CI/CD pipeline (lint → test → build) with packaged deployment.
    How
    Automates 1,000+ test executions on every run.
    • GitLab CI/CD
    • Java
    • Docker
    GITLAB CI/CD · 3 STAGES

    TESTS RUN: 0

  • 100+ TOOLS → 3–8 PER REQUEST
  • ~75% LOWER LLM API COST
  • 8 REPOS
  • 1,000+ AUTOMATED TESTS

Notes from co-passengers

Two people from the coach left a note. Verbatim excerpts from LinkedIn.

“When Shaun joined the development team for which I'm a product owner, I quickly realized the team hit the jackpot.”

“My biggest regret is that we were not able to hire him.”

GDSC Fr. CRCE

Organised one of India's international student hackathons, with participants from 20+ countries.

GDSC is where I went from learning and building technology to teaching it, and to creating chances for other students to build with it.

I joined as a web developer. By the end I was co-leading a team of 50: running workshops on Web, Google Cloud and AI, standing in front of rooms full of students, and organising an international hackathon with participants from 20+ countries.

Everything I do now, from RAG sessions to mentoring and judging hackathons, started here.

  • 50member team, co-led
  • 20+countries at our international hackathon
  • 10+workshops on Web, Cloud and AI
  • 100+students taught
Some of my best friends. My best memories. The part of college I enjoyed the most.
