Custom Software & SaaS

End-to-end custom software builds. Multi-tenant SaaS, internal tools, AI-powered platforms — engineered to scale from MVP to seed.

What's included.

Every custom software & saas engagement at Codvyx is a single, senior team — design, engineering and DevOps under one roof.

01

Multi-tenant architecture

Tenant isolation, role-based access, organisation switching, audit logs — all the things a real B2B SaaS needs.

02

Auth & identity

Email + password, OAuth, magic links, SSO (SAML / OIDC), MFA, and session management done right.

03

Billing & subscriptions

Stripe, Razorpay, Paddle — pricing pages, checkout, plan upgrades, proration, dunning, invoices, tax compliance.

04

Admin & internal tools

Superadmin dashboards, impersonation, refund flows, data exports — the tools your support team will live in.

05

AI & integrations

OpenAI, Claude, vector search, RAG pipelines, webhook receivers, REST/GraphQL APIs for partners.

06

Observability

Structured logs, metrics, error tracking, performance traces — so you know what's slow before your users do.

How we deliver.

Same four-step playbook, every engagement — predictable, written down, never surprising.

  1. Step 01

    Architecture & spec

    Data model, infra diagram, API contract, third-party integrations — written down before week one ends.

  2. Step 02

    Vertical-slice MVP

    We build one full feature end-to-end first — auth, UI, backend, billing — to validate the architecture early.

  3. Step 03

    Feature delivery

    Weekly demo, written changelog, staging environment, real users testing in parallel.

  4. Step 04

    Production launch

    Load testing, runbooks, on-call rotation handover, monitoring dashboards — you take over with confidence.

Built with the right tools.

Common questions.

Don't see your question? Drop us a line at info@codvyx.com — we reply within 48 hours.

  • 01Can you start from an existing codebase?
    Yes — we routinely take over existing TypeScript / Python codebases. We start with a written audit, agree on the next-3-month roadmap, then ship from week two.
  • 02Do you offer ongoing engineering support?
    Yes — most clients move onto a monthly retainer after launch, giving them dedicated senior capacity for new features and infra.
  • 03Where will my data live?
    On infrastructure you control — AWS, GCP, Azure or a managed Postgres provider of your choice. We do not host customer data on Codvyx-controlled accounts.
