Engineering across web, firmware, and hardware

Owner-led consulting for teams that need clear scope, working prototypes, and documentation that survives handoff - not slideware or a fake bench.

How I work

Owner-led engineering, end to end

You work directly with me - no account team and no bait-and-switch bench. I scope web, firmware, and mechanical work with clear milestones, demos, and docs your team can maintain after handoff.

What I can help with

Web & product engineering

From prototypes to production: TypeScript, Astro, APIs, and reliable delivery for your product and team.

Embedded & firmware

Firmware, embedded Linux, sensors, and interfaces - practical engineering for reliable systems.

CAD & mechanical design

Solid modeling, CAD workflows, and practical design for prototypes and small-scale production.

Managed hosting

Deployment through fully managed operations - pick the tier that matches how hands-on you want to be, across common hosting models.

Modelos 3D

Piezas paramétricas, ensamblajes y paquetes de exportación para fabricación y simulación.

Escaneo 3D

Flujos de luz estructurada y fotogrametría para llevar piezas físicas a CAD.

CFD

Flujo y térmica para conductos, carcasas y componentes con feedback accionable.

FEA

Estudios estáticos y modales para piezas estructurales - ligados a material y fabricación.

Impresión 3D

FDM y resina según material, tolerancia y acabado.

Frequently asked questions

Answers below mirror the main site FAQ - edited here so the services landing example stays consistent with Heff.world.

Typical work spans web apps and internal tools (TypeScript, APIs, Astro or similar), firmware and bring-up on embedded targets, and CAD or mechanical design when the problem crosses hardware and software. If it is not a fit, I will say so early.
We start with a short discovery call and a written scope: milestones, risks, and what success looks like. Then we iterate in small loops with demos, feedback, and adjustments so surprises stay small and decisions stay informed.
Most work is remote and async-friendly, with scheduled checkpoints. On-site or lab time can make sense for hardware bring-up, fixtures, or tight integration weeks. We can plan that when it matters.
By default you own deliverables paid for under the agreement. Details belong in the contract (NDA, license, and handoff). I am happy to align with your legal or procurement process.
You work with me. For larger efforts I may bring in trusted collaborators with your approval, but I stay accountable for integration and quality.
Use the contact form on this site or reach out on LinkedIn. A short description of the problem, timeline, and constraints is enough to start a conversation.
