METHODOLOGY

How I work

Disciplined engineering from requirements through physical breadboard verification to measured production code.

Read the brief, requirements and constraints. Identify electrical tolerances, API schemas, and real-world limits before drafting schematics or code.

RequirementsConstraintsArchitecture

Breadboard it, wireframe it or build a quick spike. Test component pinouts on the bench or validate reactive data flow in a sandbox environment.

BreadboardingWireframesFast spikes

Firmware or UI, then measure it with a scope or browser profiler. Verify ADC calibrations, eliminate ground noise, and validate responsive rendering.

FreeRTOS / ReactOscilloscopesAutomated Tests

A case study, a README and a handoff. Structure clean schematics, publish field verification notes, and deploy to automated edge pipelines.
