A large ultra-wide monitor on a minimalist black desk displays a vivid PCB layout in a professional EDA tool, featuring detailed four-layer routing, differential pairs, and ground pour cutouts. In front of the screen, a sleek mechanical keyboard and a compact USB logic analyzer rest neatly aligned. The desk surface is uncluttered, with only a small ESD-safe PCB holder containing a bare prototype board. Soft, cool-toned ambient light from an unseen window mixes with a gentle glow from the monitor, casting subtle reflections across the desk and emphasizing the layout’s colors. Photographed straight on at eye level, with the screen slightly dominant in the frame, the mood is focused and modern, highlighting the digital side of embedded and PCB design in professional photographic realism.

Embedded Firmware Development

Developing core application firmware, implementing standard RTOS environments, and writing peripheral drivers to bring your custom hardware prototypes to life and validate core functionality.

A close-up, photographic view of a mixed-signal PCB prototype clamped in a precision vise beneath an articulated microscope, set on a tidy technical workbench. The board features contrasting zones: a densely populated high-speed digital section and a carefully isolated analog front-end with op-amps and shielded traces. A slim, temperature-controlled soldering iron with a fine conical tip rests nearby, its stand clean and organized. Cool neutral lab lighting with a subtle top accent light creates delicate reflections on exposed copper, solder joints, and lens glass. Shot from a slightly low angle that looks past the soldering iron toward the PCB, the composition uses shallow depth of field to emphasize the component detail, giving a focused, methodical, engineering-lab mood in crisp photographic realism.

PCB Design & Prototyping

Schematic capture, component sourcing, and PCB layout optimized for standard manufacturing capabilities. Design of basic 3D-printed enclosures and cases for proof-of-concept testing and beta distribution.

Pricing

Prototype Scale

Every project is different, so engagements are priced based on scope rather than flat-rate menus. Most projects fall into one of three buckets:

Targeted Assistance (10–30 hours): Firmware debugging, component selection, script development, or reviewing basic schematics and layouts to help unblock your team.
Proof-of-Concept Sprints (40–160 hours): Translating an idea into a functional prototype. This includes breadboarding, core firmware development for microcontrollers, and first-pass PCB design.
Small-Batch Prototyping (160+ hours): End-to-end development of a minimal viable product (MVP). This covers schematic capture, PCB layout, firmware integration, and delivering a functional first article or a small beta production run.

Work is billed on a time-and-materials basis with clear estimates, defined milestones, and weekly reporting to ensure transparency regarding both engineering progress and budget.

Production Scale

Pricing is anchored to the level of support your project requires:

Technical Assistance: You own the core architecture; I provide the execution bandwidth. This includes component research, executing layout based on your constraints, or providing a secondary review of your schematics. This is ideal when your internal team needs extra hands to accelerate a project.
Co-development: We share responsibility for embedded firmware and PCB design. Work is structured in defined phases (component selection, schematic capture, layout, basic bring-up), with estimates and checkpoints at each phase so you can adjust scope as the project evolves.
End-to-End Prototyping: I handle the process from concept to a functional PCB and firmware baseline. This covers discovery, requirements gathering, and the delivery of a working prototype or a low-volume beta run. Pricing is phased, with fixed or capped budgets per major deliverable once the scope is clearly defined.

Most clients start small—an initial review or a short development sprint—and scale the engagement once we’ve validated fit, risk, and budget together.
