Setelio was created on March 9, 2023.
No big story behind it. Just a decision to stop building software the wrong way.
It comes from years of working across outsourcing, product companies, and consulting, and seeing the same problems repeat. Lack of experience. Too much complexity. Too many decisions that lead nowhere. Projects treated like transactions, just another deal, not something people think through.
We took a different path. Go deeper into the problem. Understand how the business actually works. Focus time, effort, and budget on what actually matters. Make decisions that do not need to be undone later.
That is what Setelio stands on. Experience, depth, and the drive to done right from the start.
We are developers and architects. We design and build services and APIs in .NET, TypeScript, and Go, React for web and mobile, and integrations between your systems. We help you deliver solutions that stay maintainable and ready to build on as your business grows.
We are DevOps and cloud specialists. We design, implement, and optimize CI/CD pipelines, infrastructure as code, monitoring, identity, networking, capacity, and cost for your workloads. We help you deliver reliably, catch issues early, and scale without losing security, performance, or cost control.
We are AI and data specialists. We design and build data pipelines, retrieval systems, chatbots, AI agents, recommendation systems, and automation across your business workflows. We help you deploy AI with governance, traceability, security, and monitoring as usage grows.
We are business apps specialists. We integrate Power Platform and Dynamics 365 with your ecosystem to automate workflows and unify business operations. We help you standardize execution, improve reporting, and speed up decisions across teams.
That is what Setelio stands on. Experience, depth, and the drive to done right from the start.
Old-school engineering thinking and cutting-edge technology, with reliability, adaptability, and long-term value at the center.
Go deeper into the problem, understand how the business actually works, and put time, effort, and budget only where it actually matters.
Build right from the start so you do not have to rebuild later, with decisions that do not need to be undone later.
Serhii began with software development and moved into system design, team leadership, and technical direction. Enough experience to see what works and what breaks.
Focus is always the same. Understand the problem before anything is built. Make the key decisions early. Keep systems simple, well-structured, and efficient to run.
Works with .NET, Azure, DevOps, and modern stacks, including TypeScript, Go, and generative AI.
His work and contributions to the .NET community were recognized by Microsoft with the MVP award for sharing knowledge and contributing to the tech community.
Stripe Certified Developer, with proven experience in building and integrating payment systems.
Lisa comes from consulting and solution architecture, working closely with companies where processes are complex or hard to manage.
Focus is on how things actually work. Where time is lost. Where systems do not connect. Then put structure where it is missing.
Deep expertise in Dynamics 365, Power Platform, and Power BI.
Her work across business systems and Microsoft technologies led to recognition as a Microsoft MVP in Business Applications, alongside certification as a Power Platform Solution Architect Expert.

Quick answers on how we work, who we partner with, pricing, and what we build, in line with how we present Setelio across the site.
Most of our work is with startups and SMBs. Startups usually need an MVP that ships fast but still has room to grow. SMBs usually need better connections between the tools they already use and less friction in day-to-day operations.
Product development and MVPs, applied generative AI and automation, data integrations and APIs, cloud and DevOps, and high-performance web experiences.
Yes. We often step into live products. We review architecture, harden integrations, improve performance, and evolve features without a full rewrite unless that is the right call.
We stay lean by design. You work with the people who actually build the product. Fewer layers, faster decisions, and budget focused on delivery rather than coordination overhead.
We start with a short intro call. Then we run discovery on scope, timeline, and budget, and send a proposal. After agreement we align on communication and workflows. Then we move into delivery and support as needed.
Fixed price when scope and outcomes are clear. Time and materials when priorities or requirements shift. Retainers for ongoing product work, improvements, and long-term collaboration. We pick the model that fits how stable your scope is.
Engineering, DevOps, AI and data, and cloud. Examples include .NET and TypeScript, React and Next.js, Azure, CI/CD and observability, integrations, Dynamics 365 and Power Platform where it fits, and applied AI where it creates measurable value.
