Custom Software Development

Custom Software, Built Secure From Day One

Web apps, SaaS platforms, APIs, SDKs, mobile apps and the cloud they run on — designed, built and handed over by senior engineers. Most teams add sign-in and security at the end. We start with them, because that is our specialty.

Sound Familiar?

The situations teams bring to us.

You need an MVP, but not a throwaway one. Something you can launch quickly that still holds up when the first enterprise customer asks about SSO, audit logs and data security.
An AI-built prototype is heading to production. It works in the demo — but nobody has checked the sign-in, the secrets, the API permissions or what happens under real load.
Your team is stretched. The roadmap needs a backend service, an SDK, an admin portal or a pipeline that your engineers have no time to build.
The platform grew without a design. Multi-tenancy, permissions and data models were bolted on, and every new feature takes longer than the last.
Releases are manual and fragile. No CI/CD, no infrastructure as code, and every deploy depends on one person remembering the steps.

What We Deliver

End-to-end delivery — design, code, tests, infrastructure and docs — with your team owning the result.

This is shipped work: the platform architecture and Supabase Postgres schemas behind Enkrypt AI, now part of Anaconda, and its public Python SDK; shared libraries and test pipelines in Node, Go and Rust for Cequence; and the products we build and run ourselves, plus this site, the Academy and the Lab.

Web Apps & SaaS Platforms

Multi-tenant SaaS, customer portals, admin dashboards and marketing sites — fast, accessible and secure, in React, Next.js, Svelte, Angular or plain HTML when that is the right call.

APIs & Backend Services

REST and gRPC APIs, services and data models in Python (FastAPI), Node.js, Go and Rust — documented with OpenAPI and built to scale.

SDKs & Developer Tools

Client libraries, CLIs and integration kits your customers enjoy using — the kind of work behind Enkrypt AI’s public Python SDK.

Mobile & Desktop Apps

Apps for Android, iOS, Windows, Linux and the web, with sign-in, passkeys and secure API access built in from day one.

AI Features & Agents

LLM features, retrieval and agents wired into your product — with guardrails, cost limits and access checks so they are safe to ship.

Cloud, DevOps & CI/CD

Infrastructure as code (Terraform, Docker, Kubernetes, Helm), CI/CD pipelines and observability on AWS, Azure, GCP or Cloudflare.

AI-Built Code Review & Hardening

Already built something with AI tools? We review the code, the sign-in, the secrets and the API permissions, then fix what matters before launch.

Handover & Support

Docs, runbooks and training so your team owns the code outright — or a retainer if you would like us to keep running it.

AI-Accelerated, Human-Owned

We use AI coding tools every day — they make us faster at the routine parts. A senior engineer still designs the system, reviews every change and answers for what ships, especially anything that touches sign-in, permissions, payments or customer data.

You get the speed of AI without the hidden risk — and if your team already built something with AI, we will tell you honestly what needs fixing before real users and attackers find it.

How to Start

Low risk, no lock-in. Most clients begin with one small, well-defined piece of work.

Step 1

Free 30-minute call

Share the idea, the deadline and what already exists. You get a straight answer on scope and approach.

Step 2

A fixed-scope first milestone

An MVP, one service, a code review or a delivery pipeline — scoped and agreed before any work starts.

Step 3

Grow, hand over, or keep us close

Keep building together milestone by milestone, take over with full docs, or keep us on a support retainer.

Quality of work done is top notch, would highly recommend.

Nitin Aravind BirurAI Researcher, Enkrypt AI

IntegrAuth brings genuinely impressive expertise in Kong Gateway and system/architecture design for DevOps infrastructure. They think through problems critically instead of just applying quick fixes, and it shows in the quality of their recommendations.
Communication is consistently great throughout a project. They keep you in the loop, explain trade-offs clearly, and are accommodating whenever requirements shift. Delivery is on time, every time, which isn't something you can say about every vendor.
Beyond the technical skills, they're just great to work with, patient, responsive, and easy to collaborate with. Highly recommend IntegrAuth for Kong Gateway or infra architecture expertise.
