We build the whole stack, so you don't manage the seams.

Who we are

Most technology projects fail at the seams — where one vendor's work ends and another's begins, where the model doesn't fit the infrastructure, where the new system can't talk to the old one. fstacks exists to remove those seams.

We are engineers first. The same team that designs your architecture writes the code, provisions the servers, hardens the security, and stands next to your operators on launch day. From GPU-backed AI infrastructure to the form a clerk fills in every morning, it's one stack, delivered by one team.

What we do

Our work concentrates in four areas that reinforce each other:

• AI solutions — production LLM applications, document intelligence and OCR, retrieval-augmented search, and speech interfaces, deployable on private, self-hosted infrastructure where data sovereignty matters.
• AI agents — assistants and autonomous workflows that connect to real systems: databases, ERPs, email, and telephony — with the guardrails and audit trails enterprises require.
• ERP systems — HR, finance, inventory, and operations platforms built for organizations with thousands of users, including careful migrations off legacy software.
• Technology transformation — modernization roadmaps, systems integration, and security engineering that take an organization from where it is to where it needs to be, without stopping the business to get there.

How we think

Three convictions shape every engagement:
