Engineering work

Selected engineering records with defined scope and evidence.

Each record states the operating requirement, delivered system, engineering boundary, and verification evidence. Private work is described without exposing customer source code, credentials, or operating data.

Internal software infrastructure

Durable Task Runtime

Problem: run deterministic work across multiple workers without losing track of completed work during failures. Built: a coordinator-worker runtime with durable records, leases, retry, requeue, and stale-result rejection. Checked: 100,000 jobs, 17 worker crashes, 2 coordinator restarts, and 0 unaccounted tasks.

Private product platform

Secure processing workflow

Problem: accept content, preserve its history, route it for review, and recover from processing failures. Built: a multi-service platform with controlled identity, provenance, hardened input handling, and CI. Customer details remain private.

Embedded measurement system

STM32H747 optical motion testbed

Problem: capture motion data on the target without host logging disturbing the measurement. Built: dual-core firmware, target-side records, shared-memory coordination, and host analysis tools.

Motor-control test platform

Dual-PMSM dynamometer

Problem: combine motor control, instrumentation, drive cycles, and real-time testing into a repeatable platform. Built: CAN-connected control and test workflows for torque, speed, power, and efficiency work.

Technical record →
Embedded controls

TI C2000 actuator controller

Problem: make command, timeout, invalid-input, and fault behavior visible on hardware. Built: a state-driven PWM controller with fault-latched shutdown and verification records.

Linux test environment

Remote control and data workflow

Problem: make deployment, model control, data retrieval, and analysis repeatable across physical experiments. Built: a managed host-to-target workflow for Linux-connected motor-control work.

Project inquiry

Start with the system and the evidence you have.

Public records show relevant work. A project discussion establishes the actual scope and confidentiality requirements before detailed material is exchanged.
