I build core products
for deep-tech startups

End-to-end product engineer • Firmware, backend, hardware, 3D, web

From circuit to cloud, I own the whole stack. I deliver the working product — firmware, real-time engines, business platforms, web apps — not just a piece of it.

About

I own the whole product

I don't specialize in one layer of the stack — I specialize in shipping the whole product. That means I can write the firmware, build the backend, ship the web app, and debug the hardware when something's wrong.

My work has directly contributed to multi-million dollar fundraising rounds at early-stage startups by delivering the core technology that moved the business forward.

Startups hire me when the roadmap is ambitious, the team is small, and the answer to "who is going to build this?" can't be "we'll hire someone eventually." Whatever the company needs to succeed, that's what I build.

"Senior engineer" isn't just about years — it's about ownership, range, and making the business work.

Core Capabilities

What I build

End-to-End Product Delivery

From circuit to cloud, I own the whole stack. Whatever the company needs to ship — firmware, backend, web, hardware — I deliver the working product, not just a piece of it.

Web Applications & APIs (Laravel/PHP)

Full web platforms on Laravel and PHP — MVC, MySQL, REST APIs, and a mixed JavaScript/TypeScript front-end. Business-critical apps shipped to real users.

Backend & Business Systems

ERP, CRM, and operational platforms built to scale. Database design, REST APIs, integrations, and the unglamorous plumbing that keeps a business running.

Embedded Systems & Firmware

Bare-metal firmware, RTOS, ARM Cortex. I2C, SPI, UART, CAN. Hardware bring-up and low-level debugging for production-grade devices.

3D, Real-Time & Performance

High-performance systems processing massive data sets in real time. Streaming pipelines, animation systems, and 3D engines for products that have to keep up.

Hardware & Circuit Design

Circuit design, schematics, prototyping. Sensor integration and analog/digital systems. From concept to production-ready hardware.

Technical Leadership

Architecture decisions, technical strategy, and cross-functional collaboration. Leading small, high-impact teams and aligning engineering with business outcomes.

Selected Work

Building products that matter

Alignment Products Inc

Firmware & Hardware Engineer

Mar 2024 – Present
Situation

Early-stage startup that needed to ship its core hardware product to validate the business.

Task

Take the product from prototype to investor-ready hardware and firmware.

Action

Owned the full hardware and firmware delivery: designed the electronic circuit, brought up the board, and developed the embedded firmware end-to-end.

Result

The product's technical validation directly supported the company's successful investment fundraising round.

Miris / Illuscio Inc

Technical Lead (previously Software Engineer)

Aug 2021 – Mar 2024
Situation

Need for a system that could handle massive 3D data sets in real time, with animation and streaming built in.

Task

Architect and deliver a high-performance, scalable real-time platform — and grow into leading the team that built it.

Action

Built a real-time point cloud processing engine, implemented animation and streaming systems, developed a VR module, and created an Unreal Engine plugin. Promoted to Technical Lead.

Result

The technology became a core differentiator, contributing to the company raising multiple millions of dollars in funding.

FishTV

Software Developer

Sep 2018 – Aug 2021
Situation

A growing media business needed to modernize its internal operations and run large-scale fishing championships end-to-end.

Task

Build the web platforms that would run the business and the events.

Action

Designed and delivered business-critical platforms on Laravel and PHP — ERP and CRM systems for the company, plus a Championship Management (GC) system for fishing tournaments. Front-end was a mix of JavaScript and TypeScript on top of a MySQL backend and REST APIs.

Result

Replaced ad-hoc internal processes with a reliable operational backbone, improved event flow and reliability for championships, and contributed to profit growth.
