The Problem
You need custom software — not a Jira board full of tickets assigned to offshore contractors you’ve never met. You need an architect who writes code, understands your business constraints, and ships working software on a predictable schedule.
Most consulting firms separate “strategy” from “delivery.” You get a senior partner in the sales meeting and a junior developer in the sprint. We don’t work that way.
What We Build
Custom SaaS Platforms
We design and deploy multi-tenant SaaS applications on Azure. Our reference architecture handles the hard problems that sink SaaS projects: tenant isolation, shared-nothing data architecture, automated provisioning, per-tenant billing, and zero-downtime deployments.
We’ve shipped production SaaS platforms managing thousands of documents across multiple tenants — with Terraform-managed infrastructure, automated CI/CD, and full audit trails.
API-First Applications
Every application we build starts with the API. Clean, documented, versioned APIs that work for your web app today and your AI agents tomorrow. We design APIs that external partners can integrate with and internal teams can build on — because the best application architecture is the one that doesn’t need to be rewritten when requirements change.
AI-Augmented Development
We use AI coding agents in our own development workflow — not as a novelty, but as a force multiplier. Claude Code, Codex, and Gemini CLI accelerate implementation while our engineering team maintains architecture decisions, code review standards, and quality gates.
The result: production-quality software delivered faster, with full test coverage and infrastructure as code from day one.

Why Big Hat Group
Founder-led delivery. Kevin Kaminski — 17x Microsoft MVP with 25 years of enterprise IT experience — is on every engagement. No bait-and-switch. The person who architects your solution is the person who builds it.
Practitioner credibility. We don’t just advise — we build production software. Our own products (BHGBrain, internal tooling) run on the same patterns we recommend to clients.
Technology-agnostic recommendations. We recommend the right tool for your problem, not the tool we’re certified to sell. Sometimes that means Azure Functions. Sometimes it means a simple App Service. We’ll tell you which — and why.
Speed and decisiveness. Small team, fast decisions. No committee approvals, no 47-slide deck before writing the first line of code. We move at startup speed with enterprise quality.
