EXPERIENCE / HOW I BUILD

From a problem to a system.

Follow how I turn a real need into an architecture, then into a working system.

01 / Before the components

Start with the problem, not the technology.

02 / System logic

Complexity becomes manageable when it becomes a system.

01Input

Sense

Read the physical world through sensors, interfaces and measurements.

TEMP / POSITION / DISTANCE / WEIGHT
02Processing

Think

Transform raw signals into reliable state, timing and control decisions.

MCU / RTOS / LOGIC / CONTROL
03Decision

Decide

Apply constraints, safety rules and system behavior before acting.

STATE / SAFETY / FEEDBACK
04Output

Act

Turn software decisions into movement, energy, data and useful work.

MOTOR / SERVO / MQTT / UI
INPUTPHYSICAL WORLDSYSTEM RESPONSE

03 / Engineering stack
