A small studio that ships
big products.
A small, senior team that builds software the way it should be built — with craft, honesty, and genuine partnership.
We started with a
simple belief.
Software development doesn't have to be a black box. Too many companies hand off their most critical projects to agencies that over-promise, under-deliver, and disappear when things get hard.
We founded Integral Stack in 2020 to do things differently. We keep our team small and senior, we communicate honestly about timelines and tradeoffs, and we embed ourselves in your organization like true partners — not vendors.
The result? Every client we've ever worked with has come back for more. 100% client retention isn't a marketing claim — it's how we measure whether we're doing this right.
Small team. Senior engineers.
A small, senior team of engineers who care deeply about the craft of building software.
Sean Michael
With over a decade of experience building software, Sean has tackled a wide range of challenges across the stack for companies ranging from startups to Fortune 500's. He has a track record for building high-quality digital products, delivering on-time, and leading engineering teams to success.
Javier Sarmiento
Previously a Primary Care Physician in Honduras, Javier discovered his love for programming while solving problems in medicine through technology. He has built mobile applications for calculating neonatal parenteral nutrition formulations and intravenous drug infusions. He finds deep satisfaction in solving engineering problems and is focused on backend development.
Leon Esteban Gonzalez
A Software Engineer from Medellin, Colombia, Leon holds a degree in Systems Engineering from Universidad EAFIT and a master's in Full Stack Web Development from ThreePoints Digital School and UPC School (Universitat Politecnica de Catalunya) in Barcelona. He specializes in the MERN stack and modern web development.
Principles, not platitudes.
These aren't aspirational words on a wall. They guide every decision, every line of code, and every client conversation.
Craft Over Speed
We write code we're proud of. Not the fastest possible solution, but the right one. Clean architecture, comprehensive tests, and thoughtful documentation aren't extras — they're the baseline.
Honest Communication
We tell you what you need to hear, not what you want to hear. If a timeline is unrealistic, we'll say so. If a feature adds unnecessary complexity, we'll push back. Trust is built through candor.
Embedded Partnership
We're your team, not a vendor. We join your Slack channels, attend your standups, and care about your business outcomes as if they were our own. Our 100% retention rate proves the model works.
Continuous Learning
We stay current so you don't have to. From the latest React patterns to emerging AI capabilities, we invest heavily in learning and experimentation. When we recommend a technology, it's because we've already battle-tested it ourselves.
Let's ship something
together.
We'd love to learn about your project. Reach out and we'll get back within 24 hours with honest next steps.
