03 — SaaS Product Engineering
We design, engineer and ship production SaaS — multi-tenant architecture, subscription billing, analytics and cloud infrastructure. No boilerplate and no shortcuts: a product built to grow, in a repository and cloud account you own from day one.
What we deliver
Multi-tenant SaaS from MVP to scale: architecture, billing, analytics and cloud.
01
The tenancy model, data access layer, API contracts, background jobs and event patterns — each decision documented with its trade-offs. For early products we favour a clean, extensible modular monolith over premature microservices.
02
Fast, accessible frontends, robust REST or GraphQL APIs, well-indexed databases with safe migrations, job queues and webhooks — CI/CD-first, tested and reviewed, written so your team can own it after handoff.
03
Stripe billing done right the first time: plans and trials, seat-based and metered pricing, annual toggles, coupons, dunning for failed payments, invoices and tax — synced by webhook so your dashboard always shows the true subscription state.
04
Email and social sign-in, enterprise SSO, role-based access and team workspaces, plus onboarding built around activation milestones so new users reach value in their first session.
05
Two layers: an internal admin for users, subscriptions, MRR and churn signals, and in-product analytics for your customers. Event tracking is instrumented from day one so product decisions rest on data.
06
AWS, GCP or Azure provisioned as code with Terraform or Pulumi; containers on ECS or Kubernetes; CDN, managed databases with backups, caching, and pipelines that test, build and deploy on every merge — with monitoring and alerting in place.
How we work
01
Define the MVP scope, target users, core workflows and stack before a line of code is written.
02
Design the tenancy model, API structure, billing model and infrastructure plan, with full documentation.
03
Two-week sprints with CI/CD from day one — working software at the end of every sprint, not at the end of the project.
04
Go live with monitoring in place, then keep improving based on real usage and growth signals.
Engagements & proof
Typical engagement
Most SaaS products launch as an MVP in six to eight weeks, then grow into a full multi-tenant platform over twelve to sixteen weeks of sprints.
Fixed-price packages for well-defined scope; hourly or retainer for evolving work. Every quote follows a scoping call.

FAQ

An MVP includes only what you need to onboard your first paying users and validate the model — usually authentication, one or two core modules and basic billing. A full product adds multi-tenancy, advanced billing, team management, analytics, SSO and production infrastructure. We usually recommend launching the MVP first and expanding on real feedback.
We pick the model that fits your isolation requirements. Early-stage products usually use a shared database with row-level tenant isolation — cost-efficient and scalable. Enterprise or regulated products can use schema-per-tenant or database-per-tenant. We document the trade-offs before writing code.
All the common Stripe models: flat subscriptions, per-seat, metered usage, tiered, freemium with upgrade paths and hybrids — plus trials, coupons, annual/monthly toggles and dunning for failed payments.
You do. Code lives in your repository from day one and infrastructure is provisioned in your cloud account. Handoff includes architecture guides and runbooks, so you are never locked in.
Yes. We start with a technical audit to understand the architecture and technical debt, then extend what you have — unless a targeted rewrite would be faster and safer than iterating on it.
Professional engagements include 90 days of post-launch support: bug fixes, performance tuning and minor iterations. After that we offer retainers for ongoing development and DevOps, or help you hire and onboard your own team.
