ABOUT

The Journey

Hey, I’m Sahaj 👋🏻— someone who’s endlessly curious about how things work and obsessed with doing them right. I don’t like half-baked anything — whether it's a side project or a production release, I’d rather take my time and get it right.

 

As an Engineer, I spend most of my time building AI Agents, integrating custom MCPs and the engineering foundations that make them useful in production. I enjoy designing architectures that connect LLMs with real-world tools and data, whether that's through OpenAI Agent SDK, LangChain, RAG pipelines, Azure services, Docker-based deployments, or backend systems that support them.

 

What interests me most is not the model itself, but how intelligent systems are engineered, integrated, and operated at scale. I’m constantly looking for ways to bridge the gap between “what exists” and “what can be better.”

 

Outside of tech? You’ll find me chasing leather on the cricket pitch or disappearing into the wild with a backpack and no signal 🌄🏏. If it’s not code, it’s probably a sunset. Or both.

JOURNEY

BARCLAYS

PUNE, INDIA

Software Developer - BA4

April 2025 - Present

  • Led development of multi-agent market intelligence platform using Azure AI Foundry and OpenAI Agent SDK, orchestrating a master agent with 10 specialized sub-agents to synthesize real-time financial news while reducing manual research aggregation time by an estimated 4 hours/day for 30+ IB analysts.
  • Designed a multi-agent framework using Microsoft 365 Agent Toolkit with intent-based LLM routing across 3 specialized agents for onboarding, HR support, and MCP-backed documentation queries for a 5K-user pilot.
  • Engineered a RAG-powered IT support agent with semantic search over indexed internal knowledge bases to autonomously resolve employee queries and reduce overhead by 20+ hours weekly.
  • Delivered a high-scale Message Center agent using Microsoft 365 Agent Toolkit and Graph API, scaled to 50K+ colleagues with 10K+ daily active users to surface curated GenAI releases for senior leadership, reducing dependence on elevated access roles through a TypeScript/YAML-based agentic architecture.
  • Architected a custom MCP server integrating Salesforce CRM into a conversational AI agent for executive stakeholders at the CEO desk, eliminating manual CRM lookup and reducing lookup time from 1 minute to 500 ms.

Technology Graduate Developer - BA3

July 2024 - March 2025

  • Identified and remediated an AI security vulnerability allowing a Copilot agent to access 850+ restricted websites and implemented a PowerShell scripting automation to enforce restrictions and prohibit content retrieval.
  • Created Azure dashboards using Azure Functions (Node.js/TypeScript) and Cosmos DB to process datasets for 100K+ users; integrated Graph API with exponential backoff and developed KQL dashboards in Azure Data Explorer to monitor call quality metrics across 5+ regions.

Software Developer Intern

May 2023 - July 2023

  • Built Admin & User dashboards for the Barclays Now portal using Angular and Spring Boot for a pilot of 200 users in an Agile setup.

PROJECTS

DocuShieldAI

Developed a full-stack microservices app (React.js + FastAPI) for automated PDF redaction using Tesseract OCR and a 3-layer NLP pipeline (Presidio, spaCy, Regex) to irreversibly remove PII at the pixel level. Optimized backend performance with FastAPI’s async features and thread pooling to handle concurrent OCR/NLP tasks. Deployed lightweight, Dockerized services on low-resource cloud environments (512MB RAM) using slim images and compact NLP models. Enabled fine-grained user control over redaction of 20+ sensitive entity types for enhanced privacy and compliance.

IETLingo

IETLingo is a student-driven platform I co-developed to streamline knowledge sharing around internships and placements within our institute. Built using Angular, Node.js, and MongoDB, it provides authenticated users with features like interview question banks, experience sharing, and real-time filtering across companies. With a focus on data security, community-driven moderation, and inclusive academic networking, IETLingo empowers students with valuable insights, promotes respectful interaction, and fosters a collaborative learning environment.
