Shipping Better Software
Our Story
Built on Honest Engineering
SandBox Union began in 2020 with a clear idea: high-impact software doesn't come from selling buzzwords, it comes from shipping well-designed systems, fast.
What started as a small engineering shop has grown into a full product, platform, and data practice serving national legal, healthcare, and automotive organizations.
Today, we build critical software and infrastructure for teams who need more than contractors—they need partners who think strategically, move quickly, and deliver reliably.

Let's Talk
Building with Purpose & People
Tiffany Eng, Founder and CEO, leads SandBox Union as a minority and woman-owned business committed to redefining what software development can be—human-centered, transparent, and built on trust.
With deep expertise in enterprise architecture, product strategy, and technical leadership, Tiffany brings a humanistic approach to an industry often dominated by ego and jargon. She believes the best software comes from listening first, designing with empathy, and empowering teams—both clients and developers—to do their best work.
Under her leadership, SandBox Union has become a trusted partner to organizations navigating digital transformation, building mission-critical platforms, and modernizing legacy systems. Her focus on mentorship, transparency, and sustainable engineering practices has shaped a company culture where quality and collaboration aren't optional—they're foundational.
"Technology should serve people, not the other way around. We build systems that work for real humans solving real problems—with clarity, care, and no BS."
