Who Am I?

I build software that ships to engineers at some of the world's largest automotive and aerospace companies. At MathWorks, I work on Simulink FMU Builder - a product used by teams building the systems inside cars, aircraft, and industrial machinery. I joined as an intern and have grown into Software Engineer 2, picking up depth across the stack along the way.

I care as much about why something gets built as how. I am drawn to problems where engineering decisions have a direct, measurable impact on users and the business. The most interesting work usually sits at the intersection of technical depth, product thinking, and understanding what customers actually need. Lately I've been exploring how agentic AI can meaningfully improve engineering workflows.

I also cleared CFA Level I, born from a genuine interest in how businesses and markets work. Outside of work, I lost 50 kg over a couple of years through dedicated fitness, play guitar, read a fair bit, and I'm a Level 7 Google Maps Local Guide - basically an excuse to visit new places and write about them.

My Journey

The Path So Far

2026 - Present

Software Engineer 2

MathWorks

  • Modernized the FMU Builder app backend for automotive and aerospace customers by decomposing monolithic logic into independently testable modules, cutting testing time ~4× (45 min → 12 min).
  • Slashed customer support tickets by ~83% per release by surfacing tunability parameter root causes and fix guidance directly in-product - eliminating the need for customers to engage Technical Support and engineering to debug.
  • Reduced FMU generation time ~6× (60s → <10s) by introducing a CI/CD-friendly JSON config system, while reducing errors and ensuring idempotency across teams.
  • Optimized agentic AI tooling for development workflows, cutting weeks of investigation time, reducing token consumption per query, and measurably improving developer efficiency.
2024 - 2025

Associate Software Engineer

MathWorks

  • Architected and delivered the FMU Builder Wizard app from scratch in JavaScript/MATLAB, replacing a rigid legacy dialog and cutting dev cycles by 33% through a purpose-built testing framework.
  • Accelerated onboarding to proprietary JS libraries from zero to productive in 2 weeks; partnered with QA and Docs to harden error messaging and maintained a <2-day bug resolution SLA.
  • Improved developer productivity by overhauling Simulink FMU export diagnostics to surface precise root causes and actionable remediation steps.
