About Me

Joel Jaison is a Generative AI Developer at IBM, Kochi, building production-grade multi-agent systems, RAG pipelines, and LLM guardrails on cloud infrastructure. My work spans agentic orchestration (LangChain, LangGraph, A2A), backend services (Python, FastAPI), and observability tooling — all shipped on OpenShift with Jenkins CI/CD.

I graduated in Computer Science Engineering from Sahrdaya College of Engineering & Technology (CGPA: 7.6) and have been hands-on with AI-first products since my internship days. Beyond the day job, I’ve won hackathons (BeachHack 2025 🥇, IBM GenAI Conclave 2024 🥈, Global Game Jam Kerala 2026 🥈), written technical blogs on Dev.to, and enjoy sketching as a creative outlet.

Experience

Software Developer — IBM

Jul 2025 – Present · Kochi, India

  • Modernized observability for Watsonx Orchestrate by leading the migration of distributed tracing from Jaeger to Langfuse with external ClickHouse collectors, and built the APIs that expose those traces for real-time agent governance and monitoring.
  • Eliminated manual regression-testing effort by automating 200+ test cases with a Pytest / Playwright framework wired into Jenkins, GitHub, and TestRail; watsonx-driven failure analysis auto-files and validates defects in under 30 seconds.
  • Hardened the control plane by building content, output-length, secret-detection, and SQL-sanitization guardrails that plug into every agent type (LangGraph, A2A) and tool type (Python, Langflow, OpenAPI, MCP) — shipped as FastAPI services on OpenShift.
  • Extended the RAG pipeline with Milvus-based ingestion connectors for external data sources, widening the range of data agents can reliably retrieve from.

Software Developer Intern — IBM

Jan 2025 – Jun 2025 · Kochi, India

  • Built the data-fetching pipeline connecting Db2 to watsonx.data, giving the platform a direct, reliable path to pull enterprise data for downstream UI and APIs.
  • Shipped new watsonx.data UI features end-to-end using React and IBM’s Carbon Design System, from spec to production release.
  • Owned the frontend migration from React 17 → React 19, adopting the new ref-as-prop pattern and retiring deprecated APIs.

Frontend Web Developer — Flora Extracts

Feb 2024 – Jun 2024

  • Designed and implemented responsive web interfaces using React, Tailwind CSS, and Framer Motion.
  • Improved user experience through interactive and visually appealing frontend components.

Alexa Skill Developer Intern — Inclusys Org Foundation

May 2023 – Jun 2023 · Remote

  • Built Alexa Skills for elderly memory exercises and conversational prompts, raising engagement by 30%.
  • Deployed voice services on AWS Lambda, maintaining 99% uptime.

Tech Lead — GDSC Sahrdaya

Aug 2023 – Dec 2024

  • Managed technical aspects of the club’s activities, events, and workshop delivery.

Pakt

Multi-agent negotiation app where each user gets a personal AI agent that knows their tastes, schedule, and budget — when a group wants to plan a movie night or dinner, the agents negotiate with each other in a shared chat, searching real venues and converging on a single confirmed plan, with humans able to take over at any point. Built for the H0: Hack the Zero Stack hackathon (AWS DynamoDB + Vercel + Next.js).
