01
Design doc first
Data model, tenancy, auth and the honest claims of the product, agreed before code.

Web App Development You Can Inspect First
Most agencies show you screenshots. We hand you URLs. OpsCores is a live multi-tenant SaaS with real billing. The Scanly web tools process documents entirely in your browser, by architecture. Five developer tools run in production on our own cluster. Everything we would build for you, we have already built and are running for ourselves.
What you get
Multi-tenant SaaS, done properly
Tenant isolation enforced in the database with row-level security, entitlements decided on the server, and billing wired to a real payments provider.
Privacy as architecture
Where a promise like "files never leave your device" fits the product, we enforce it structurally: no upload endpoint exists, and the build fails if a network call creeps in.
Fast and indexable
React applications prerendered to real HTML, so crawlers, previews and users on slow connections all get content, not an empty shell.
Run, not just delivered
TLS, backups, monitoring and deploys on infrastructure we operate daily. Or handed over to yours, documented.
Proof you can open
Not case studies you have to take on trust. These are live, and you can use them before you ever talk to us.
How we deliver it
02
Build typed and reviewed
TypeScript front end, typed APIs, migrations under version control, changes through review.
03
Prove the promises
The product's claims become tests and build-time checks, so they cannot silently rot.
04
Operate or hand over
We run it with monitoring and backups, or your team does, with runbooks. Both paths documented.

Frequently asked
Can we see something you have actually built?
Yes, right now, without asking us: opscores.com is a live SaaS, scan.deplyra.com runs five browser-side document tools, and pmwriter, kesvara, auditprep, dependencywatch and devopsagent are live on deplyra.com subdomains. Open them and judge the work.
Which stack do you use?
Our default is React and TypeScript in front, FastAPI or Supabase behind, PostgreSQL underneath, deployed on Kubernetes. If your team lives on a different stack we adapt; the design-doc-first process is the constant.
Do you also host and run what you build?
Yes. Our own products run on a Kubernetes cluster we operate, with TLS, offsite backups and monitoring. Yours can run there, on your cloud, or be handed over entirely; the code does not depend on us.
