I'm Shawn Spitzfaden, a programmer and engineer who turns technical ideas into polished, usable systems. I like work that is visually intentional, technically precise, and clear enough for recruiters, collaborators, and teams to immediately understand.
My background spans software, simulation, engineering, and lab work, with an emphasis on making practical things look and feel professional.
Performance-focused work for simulation, real-time systems, and lower-level technical tooling where speed and control matter.
Example projects
Desktop applications, engineering utilities, and polished internal tools where a strong UI and structured architecture help teams move faster.
Example projects
Modern frontend and full-stack web work, especially interactive portfolio experiences, dynamic interfaces, and product-focused UI.
Example projects
Automation, pipelines, data processing, and technical scripting for creative workflows and engineering support tasks.
Example projects
Structured application development and software that benefits from strong typing, portability, and familiar enterprise patterns.
Example projects
I like to show engineering through specific problems solved, not just broad claims. These are the kinds of projects recruiters can scan quickly.
Project work focused on position, velocity, acceleration, and the math behind controlled motion and dynamic behavior.
Project examples
Hands-on embedded work that connects software with hardware for automation, sensing, or real-world interaction.
Project examples
Numerical methods and engineering analysis used to predict behavior, compare approaches, and validate results.
Project examples
Practical engineering work involving data collection, test setups, measurement accuracy, and repeatable process design.
Project examples
This is the section where I show the actual scope of my current lab role, from compliance testing to validation, tracking, and calibration work.
Compliance testing under standards such as UL 61010-1 and related product safety requirements, with an emphasis on careful execution and reporting.
Project examples
Validation of mechanical assets and fixtures to confirm they are ready for repeatable use in the lab and support safe, consistent testing.
Project examples
Power supply quality validation focused on stable operation, predictable behavior, and confidence in the test setup before results are recorded.
Project examples
Thermocouple validation work to make sure temperature measurements are trustworthy, traceable, and suitable for compliance and lab reporting.
Project examples
Customer sample tracking and deposition workflows that keep incoming material organized, identifiable, and ready for the right test path.
Project examples
Calibration responsibilities for test equipment and support tools, helping keep measurements reliable and aligned with lab standards.
Project examples
I prefer showing proof over buzzwords. These are the areas where I have real hands-on experience and where I can add value quickly on a team.
Next.js, React, Python, GLSL/OSL tooling, and workflow automation for technical projects.
Numerical methods, fixture design, analysis, and structured problem-solving in real-world systems.
Safety testing, instrumentation, calibration-aware measurement, reporting, and process improvement.
