SaaS Development
Multi-Tenant, Scalable, Production-Ready
Multi-tenant SaaS products engineered for scale and uptime
B2B SaaS is our bread and butter. We architect multi-tenant platforms, wire up subscription billing, build admin consoles, and operate the backends that keep products like TestReach running for ACCA, British Council, and CIPS.
We treat reliability as a first-class feature. Your SaaS will ship with sane observability, rate limiting, backups, and runbooks on day one — not bolted on after the first 3 AM incident.
What You Ship With NerdDevs
- Multi-tenant architecture with row-level or schema-level isolation
- Subscription billing on Stripe, Paddle, or regional processors
- Admin / impersonation tooling for your support team
- Role-based access control, audit logs, SSO, and SCIM
- Observability, alerting, and on-call runbooks
What We Build
Six focus areas where we bring deep, shipped-in-production experience.
Multi-Tenant Foundations
Tenant isolation, onboarding flows, plan limits, trial management, and data residency controls — decided up front, not retrofitted.
Billing & Subscriptions
Stripe, Paddle, or regional gateways. Plan upgrades, proration, invoices, tax, dunning, and churn instrumentation.
Admin & Support Consoles
Internal tools for impersonation, refunds, feature flags, and tenant-level config — so your support team does not file Jira tickets for every request.
Auth, SSO & SCIM
OAuth, email/password, magic links, SAML SSO, SCIM provisioning, and enterprise-grade password policies.
APIs & Webhooks
Versioned REST or GraphQL APIs, signed webhooks, rate limiting, and first-party SDKs when it matters.
Reliability Engineering
Load tests, incident runbooks, structured logs, metrics, tracing, and a postmortem culture.

Frequently Asked Questions
Single-tenant or multi-tenant — how do you decide?
For most B2B SaaS we recommend pooled multi-tenant with tenant-scoped queries by default, and a silo option for enterprise customers with compliance requirements. We document the decision early so migrations do not bite later.
Which billing provider do you recommend?
Stripe for global B2B SaaS, Paddle when you want a merchant-of-record model for tax simplification, and bKash/local gateways when selling into Bangladesh or SE Asia. We have shipped all three.
Can you migrate our legacy product to a SaaS model?
Yes. We have migrated PHP, Django, and legacy Node monoliths to modern SaaS architectures — usually in phases so revenue keeps flowing during the cutover.
Do you provide ongoing SRE / on-call?
Yes, under a monthly retainer. We monitor uptime, respond to alerts, ship patches, and hold a monthly reliability review with your team.
