SaaS Product Engineering & Multi-Tenant Architecture
Building scalable, maintainable B2B and consumer SaaS platforms from zero to scale. Designed for predictable scaling, multi-tenant database isolation, frictionless recurring billing, and sub-second application performance.
The Engineering Philosophy for Modern SaaS
Too many MVPs are built quickly without considering data isolation, indexing, or transaction boundaries. When the platform signs its first 20 enterprise clients, the database slows to a crawl, background jobs fail silently, and migrations become terrifying.
I architect SaaS systems with a clear separation of concerns: modular Next.js frontends, strict database schemas in PostgreSQL or MongoDB, asynchronous worker queues (BullMQ/Redis) for background tasks, and clean webhook handlers that never drop a payment event.
What I Architect & Deliver
Multi-Tenant Database Architecture
Schema-per-tenant, row-level security (RLS), or partitioned single-table tenancy chosen based on your compliance, cost, and query complexity requirements.
Subscription Billing & Entitlements
Battle-tested Stripe, Razorpay, and paddle integrations handling seat-based pricing, usage metering, tiered trials, and idempotent webhooks.
Authentication & RBAC
Enterprise SSO (SAML/Okta), social logins, multi-factor auth, session management, and granular role hierarchies (Admin, Member, Billing, Viewer).
Real-Time Dashboards & Analytics
High-speed Next.js React dashboards utilizing virtualized rendering and Redis window caches to display dense time-series metrics without browser lag.

Frequently Asked Questions
Do you work directly or outsource development to a junior team?
I work directly with founders and engineering leaders. When you engage me, you are getting my 18+ years of hands-on architectural design, coding, and direct code commits, not an anonymous junior team.
Can you rescue or re-architect an existing slow SaaS codebase?
Yes. I frequently perform technical due diligence and code audits to identify database N+1 bottlenecks, unindexed query scans, memory leaks, and brittle third-party integrations, restructuring the architecture iteratively without requiring a full rewrite.
