About
Embedded systems engineer building real-time target software for HIL and automotive diagnostics.
I build production software for automotive hardware-in-the-loop systems: diagnostics protocol stacks on real-time targets, embedded Linux/QNX platform layers, and the secure infrastructure underneath.
At MathWorks I've grown from intern to Software Engineer II, owning features used by Ferrari, McLaren, Lucid, and other OEM teams. My work displaces costly third-party toolchains and keeps HIL regression pipelines moving.
Platform depth
systemd bring-up, cross-compiled services, TLS, and QNX/Linux dispatch across ARM and x86 targets.
Ship with confidence
Automated regression and verification across 5+ concurrent production release branches.

Software Engineer II
May 2026 – Present- Designed a modular, codegen-compatible state-machine architecture integrated into Simulink Real-Time: deterministic UDS (ISO 14229) over ISO-TP / CAN FD executing on target hardware. Answers 5+ years of demand from 13+ OEMs and displaces ~$50K third-party diagnostic tools.
- Diagnosed ~2.5 min boot stalls caused by systemd waiting on network-online.target in disconnected HIL environments. Re-architected the service dependency chain to decouple network readiness from application bring-up, cutting cold boot to ~30 sec (~5×).
- Managed automated regression and verification pipelines across 5+ concurrent production release branches.
- Own release readiness and library compliance for the diagnostics product ahead of launch.

Impact
Selected engineering contributions with measurable outcomes across diagnostics, platform software, and HIL infrastructure.
Real-Time UDS Diagnostics Engine
13+ OEMs- Challenge
- Automotive teams needed on-target UDS without ~$50K Vector CANape / dSPACE licenses.
- Approach
- Designed a modular, codegen-compatible state-machine architecture integrated into Simulink Real-Time.
- Impact
- Deterministic UDS (ISO 14229) over ISO-TP / CAN FD on real-time target hardware for Ferrari, Lucid, McLaren, Liebherr, and others.

Boot Time Optimization
~5× faster- Challenge
- HIL racks boot offline, but systemd blocked startup on network-online.target for ~2.5 minutes.
- Approach
- Traced the dependency chain and decoupled network readiness from application service bring-up.
- Impact
- Cold boot dropped to ~30 seconds, unblocking automated regression pipelines on disconnected targets.

Encrypted Target-Control Stack
3 platforms- Challenge
- MQTT-based target control lacked encrypted transport for security-sensitive customer deployments.
- Approach
- Led a ground-up migration to REST/HTTPS with Protobuf schemas, OpenSSL TLS, and credential-based auth.
- Impact
- Shipped across x86_64 and ARM aarch64 with improved reliability and encrypted service orchestration.
RESTHTTPS/TLSProtobufOpenSSL
Target Time Synchronization
3 releases- Challenge
- Customers needed synchronized clocks across QNX and Linux targets for multi-ECU HIL scenarios.
- Approach
- Shipped four public APIs, an NTP-sync UI dialog, and platform-specific dispatch end to end.
- Impact
- Resolved 15+ production defects and delivered across three product releases.
