About Me

Iā€™m an embedded software engineer focused on cryptography, security, and platform reliability.

I currently work on hardware-accelerated cryptographic systems, where I design and integrate low-level drivers, validation tooling, and automated test frameworks for production microcontrollers. My work sits at the intersection of hardware, firmware, and security requirements, with a strong emphasis on correctness, determinism, and long-term maintainability.

I enjoy problems that require careful reasoning ā€” things like interrupt behavior, DMA interactions, constant-time execution, and making complex systems behave predictably.

What I Work On

  • Hardware-accelerated cryptography (AES, SHA, ECC, TRNG, PKE)
  • Secure boot, key provisioning, and hardware-rooted trust
  • Embedded test automation and host-side validation
  • ASPICE / MISRA-C / ISO-21434 aligned development
  • Tooling that makes embedded development more repeatable and less error-prone

How I Like to Work

I value:

  • Clear interfaces and well-defined responsibilities
  • Testability, even in low-level embedded systems
  • Documentation that explains why, not just what
  • Writing code that someone else can confidently maintain

I tend to gravitate toward roles where correctness and security matter as much as performance.

Outside of Work

Outside of engineering, I spend time on activities that balance focus, discipline, and hands-on problem solving.

I am a practitioner of Balintawak and an apprentice feeder, which has strengthened my appreciation for timing, precision, patience, and calmness under pressure. The discipline emphasizes structured progression, controlled responses, and clear decision-making in dynamic situations ā€” skills that translate directly to technical problem-solving and debugging under time constraints.

I also have a strong interest in Japanese performance cars, particularly turbocharged four-cylinder platforms and Subarus, and enjoy understanding how mechanical and control systems interact and how design tradeoffs affect performance and reliability.

In my free time, I enjoy:

  • šŸ–Øļø Designing and 3D-printing small functional parts
  • šŸ› ļø Hands-on tinkering and learning through building
  • šŸŽ® Video games and other problem-solving oriented games
  • šŸ‚ Snowboarding
  • šŸ• Spending time with my dog

These interests help me stay balanced, curious, and engaged both inside and outside of work.
