Delta Systems is a US-based custom software engineering firm with leadership based in Missouri, Kansas, and Arizona. We build and modernize business-critical software for B2B companies with 15–100 employees across the United States.

Most engagements are staffed with five or fewer team members: the same people from scoping through delivery.

Who We Are
At Delta Systems, we're software engineers, solution architects, and technical strategists. But more importantly, we're the kind of people who care whether the thing we built actually worked for you six months later.
Delta Systems builds and modernizes business-critical web and mobile products for US-based companies. We have deep roots in Ruby on Rails, and a full-stack skill set that includes React, React Native, Python, Laravel, and AWS. We've been at this for years, which means we've seen most of the ways software projects go sideways, and we've built our process around preventing them.
What makes us different isn't a methodology or a tech stack. It's how we show up: low ego, high accountability, and a genuine interest in the outcome, not just the deliverable.
Our Leaders
Jake Sheafer, CEO
Jake didn't come up through engineering. He came up through the business side, which turns out to be a pretty useful perspective for running a software company.
He started in traditional media, leading a digital transformation for a print publication group and building an in-house development team from scratch. That experience taught him early that custom software isn't a support function: it's the engine.
At OrderUp, he scaled the business to facilitate over 5,000 deliveries per week before ultimately selling it to GrubHub, another early proof that well-built software, applied to the right problem at the right time, could change how an entire industry operated.
After a successful exit from media in 2018, Jake turned his focus entirely to software development, investing in and ultimately leading Delta Systems. Today, Delta Systems stands as a testament to his commitment to technology and its transformative power.

Justin Edwards, CIO
Justin has spent over 13 years doing the work that most consultants only advise on. He started by building and selling his own consulting firm, and that experience gave him something most engineers never develop: a real understanding of what it costs a business when software fails, slows down, or scales badly. That commercial grounding shapes how he thinks about every technical problem he touches.
At Delta, Justin works directly with founders, CTOs, and technical leads on the complex, systemic challenges that don't have tidy answers.
Outside of Delta Systems, Justin supports StriveDB, a SaaS platform built for victim services organizations that require airtight data security and straightforward reporting. He also co-hosts the SaaS That App podcast with Delta's Head of Engineering, Aaron Marchbanks.

Aaron Marchbanks. Head of Engineering
Aaron leads the engineering organization, setting technical standards, managing client relationships, and making sure what gets built actually maps to what clients need.
His superpower, as he'd put it, is people leadership: turning a group of skilled developers into a team that communicates clearly, moves decisively, and ships work worth shipping. He's also co-host of the SaaS That App podcast alongside Justin.

How the Delta Systems team works
We've refined this over a long time, and the short version is: we treat your project like it matters, because it does.
Design and prototyping
Design and engineering work together from day one. We build early prototypes, get real usability feedback, and make UX decisions before they become expensive engineering problems to untangle later.
Is Delta Systems the right fit for you?
We work best with US-based companies that are building or modernizing a product worth scaling, and who want a partner that's invested in whether it succeeds, not just whether it ships.
The best way to find out if we're a match is a direct conversation. Tell us what you're working on and we'll give you an honest read on whether we're the right team for it.
