About

I'm a Model-Based Development Engineer with 3+ years building safety-critical automotive control systems at KPIT Technologies. My work spans MATLAB/Simulink algorithm development, AUTOSAR architecture, and ISO 26262 compliance — delivering production software for Cummins powertrains across multi-ECU platforms.

What drives me is the engineering culture behind elite precision — where milliseconds matter, failure is not an option, and every decision is fully traceable. That discipline I carry from the racetrack into every model, every design review, and every line of code.

Sept 2023 — Present Current
Software Engineer — Model-Based Development
KPIT Technologies  ·  Client: Cummins Inc.  ·  Bengaluru, India
  • Own end-to-end V-model delivery of implementation and verification change requests for Air Handling & Combustion Controls across four diesel and gasoline programs — ASPICE requirements through Simulink/Stateflow design, Embedded Coder, and MIL/SIL.
  • Build AUTOSAR Simulink/Stateflow models to MAAB and ASPICE SWE.3/SWE.4, and coordinate ARXML and calibration changes with the PREEvision team.
  • Keep every delivery Polyspace-clean (zero critical findings, full MISRA-C / CERT-C) and drove the team's MISRA-C rollout by clearing the check backlog.
  • Present at the customer Design Review Board to Cummins' global forum (India, US, China, UK) with a zero-failure record and 4.8/5 CSAT — once caught a design gap the reviewing architect had missed.
  • Trained 17 engineers in composition testing (archived to KPIT's training library) and proposed splitting the 22-person team into focused sub-teams, now adopted.
  • Migrated legacy Core2 AUTOSAR components to CSAR, and run L2/L3 composition and bench testing on Cummins' US rigs across decision, condition, and MC/DC coverage.
Jan 2023 — Sept 2023 Internship
Intern — Model-Based Development
KPIT Technologies  ·  Pune & Bengaluru, India
  • Developed and validated Simulink/Stateflow models for automotive control algorithms with complete requirement traceability across the software development lifecycle.
  • Conducted ECU verification and validation using CAN protocol and bench-testing; identified edge-case failures and supported MIL/SIL validation of model-based changes.
  • Authored requirement specifications for logic updates and performed ECU diagnostics, supporting cross-functional teams in root-cause analysis and documentation.
Sept 2021 Internship
Intern — Embedded Systems & Vehicle Integration
Volvo / Martial Motors  ·  Bengaluru, India
  • Supported engine assembly, ECU tuning, and system-level testing across vehicle platforms; gained hands-on exposure to sensor-ECU integration and real-time DTC monitoring.
  • Worked with a specialized body-work and vehicle-service team, which provided insight into the premium-vehicle service workflow.

Projects

A deliberate model-based-design suite spanning the three pillars of production powertrain software — closed-loop control, OBD diagnostics, and ISO 26262 functional safety — each with a live in-browser simulation, traceable requirements, and a model-as-code repo.

SimulinkStateflowEmbedded Coder
In Progress
Boost-Pressure Control Model
A closed-loop diesel turbocharger boost-pressure (air-path) controller built the full MBD way — discrete PI + feed-forward + back-calculation anti-windup, a speed×load setpoint map with modelled turbo lag, ECO/SPORT/RACE drive modes, and an INIT→OFF→CRANK→RUN→FAULT Stateflow supervisor. Requirement-traceable, MISRA-aligned generated C, with a live in-browser simulation of the same control law. MIL/SIL + MC/DC coverage planned on a personal MATLAB.
StateflowOBDMISRA-C
In Progress
Sensor Diagnostic Monitor
An OBD-style diagnostic monitor for a redundant sensor pair — range / rate / correlation rationality, debounced fault confirmation, DTC + freeze-frame + MIL, and healing — modelled in Simulink/Stateflow, MISRA-aligned C, with an AUTOSAR Classic SWC. Logic re-proven headlessly (REQ-DIAG-001…010, all pass).
ISO 26262E-GasStateflow
In Progress
Torque Safety Monitor
An ISO 26262 E-Gas three-level torque monitor for the ASIL-D unintended-acceleration goal — independent permissible-torque (L2), question/answer watchdog (L3), FTTI-bounded reaction, and a latched safe state. Simulink/Stateflow → MISRA-aligned C, with an AUTOSAR Classic SWC. Logic re-proven headlessly (REQ-SAF-001…010, all pass).

Why Precision Engineering is Personal

The same standards that decide a championship are the ones I hold safety-critical software to — real-time, sensor-driven, and tested for every case before it ever runs.

"Milliseconds decide a race. They also decide whether a control loop holds at the limit. I build both the same way — no margin for error, every path tested."

— Saaim

Formula 1 — Mercedes-AMG Petronas

A rolling embedded-systems lab: ~300 sensors feeding 1,000+ telemetry channels, a terabyte of data a weekend, and one mandated spec ECU running its control strategy on a 1 ms loop. It's the sharpest version of what I do — real-time control and safety-critical code that can't fail at 360 km/h.

MotoGP — Marc Márquez

A spec ECU fuses IMU, GPS and wheel-speed to run traction, anti-wheelie and engine-braking control. Márquez holds ~65° of lean mid-corner — and once saved a 70.8° slide at 67 km/h — then the same electronics fire the bike down the straight at 360+ km/h. The same discipline I bring to every ECU review.
