SaaS & MVP Development
Naman Gundaniya builds SaaS products and MVPs for founders — authentication, billing, multi-tenancy and admin tooling included, because those are what turn a prototype into something you can charge for. Built to validate the idea quickly without the shortcuts that force a rewrite at your first real customers.

Who this is for
- Founders validating an idea with real paying users
- Non-technical founders needing a technical counterpart
- Teams replacing a spreadsheet-and-Zapier process with a product
- Companies spinning an internal tool into a sellable product
What you get
- Deployed multi-tenant SaaS application
- Authentication with roles and team accounts
- Subscription billing and plan gating
- Admin interface for support and operations
- Onboarding flow instrumented so you can see where users drop
- Analytics on the events that indicate real usage
The parts founders underestimate
The feature you are excited about is usually the fastest part. What consumes an MVP timeline is everything around it: signup, email verification, password reset, team invitations, subscription plans, upgrade and downgrade, failed payments, an admin view for support, and a way to see whether anyone is actually using the thing. Scoping those in from the start is the difference between a six-week build and a six-week build followed by six weeks of surprises.
Multi-tenancy decided on day one
Whether tenants are separated by a column, a schema or a database is close to irreplaceable once data exists. Getting it wrong means a migration under load with real customers watching. It is a thirty-minute conversation before the first table is created, and a very expensive one afterwards.
Fast without the shortcuts that cost you
Some shortcuts are correct in an MVP: skip the feature, use a managed service, hardcode the thing you might never need. Others are not: no migrations, no tenant boundary, no auth model, secrets in the client. The first kind saves time you keep. The second kind borrows time at a punitive rate, repayable exactly when you get traction.
Instrumented so you learn something
An MVP exists to answer a question. If you cannot see where users abandon onboarding or which feature retains them, you have built software without buying the information you were paying for. Event analytics on the flows that matter is part of the build, not a later addition.
How the engagement works
- 01
Discovery
Establish what the MVP has to prove, and cut everything that does not serve that. The hardest and most valuable part is deciding what not to build.
- 02
Design
Wireframes for the core flows — signup, onboarding, the main loop, billing — reviewed before implementation starts.
- 03
Build
Weekly demos against a live deployment, so scope can change while changing it is still cheap.
- 04
Ship
Launch with billing live, analytics recording, monitoring configured and 30 days of support.
Technology
- Application
- Next.js for server rendering, streaming and a single deployable unit — fewer moving parts for a small team to operate.
- Data & auth
- Supabase or Convex for managed auth, row-level security and real-time subscriptions; Postgres directly where the schema needs full control.
- Billing
- Stripe subscriptions with plan gating enforced server-side, because client-side gating is a suggestion.
- Insight
- PostHog for funnels and retention on the flows that indicate whether the product is working.
Proof
AVENUOR — Home Asset Management SaaS
AVENUOR is a home and society asset management SaaS live at avenuor.com. It gives homeowners a central registry for appliances, vehicles and building assets — with AI-powered invoice extraction, per-asset health scoring and warranty reminders — and gives housing societies a multi-user console for shared registers, work orders and compliance documents. Built with Next.js and React, deployed on Vercel.
Task-Flow - AI Task Management
Task-Flow is a MERN-stack task management application with role-based access control and AI-assisted prioritisation. It covers team task tracking, assignment and collaboration, with the AI layer suggesting priority order and surfacing productivity patterns rather than replacing human judgement.
ScanX - AI Note Taker
ScanX is an AI note-taking web app built with Next.js, Convex and LangChain. Users upload a PDF, the text is chunked and embedded into a vector index, and a retrieval-augmented chat answers questions against that document with citations back to the source pages.
Frequently asked
How long does an MVP take to build?
Most MVPs land between four and ten weeks depending on scope, with billing, auth and multi-tenancy accounting for more of that than founders expect. The discovery call produces a real timeline against a specific scope rather than a generic range.
What should an MVP deliberately leave out?
Anything that does not help answer the question the MVP exists to answer. Common correct omissions: granular permissions, an integrations marketplace, native mobile apps, internationalisation, and dashboards nobody asked for. Rarely correct to omit: authentication, billing, migrations, and the tenant boundary.
Will the MVP need rewriting when it grows?
Parts of it should — that is a sign it worked. The goal is that the foundations survive: schema with migrations, a real tenant boundary, server-enforced auth. Those are what make the next stage an extension rather than a restart, and they are cheap to do correctly the first time.
Do you work with non-technical founders?
Frequently. That means explaining trade-offs in terms of cost, time and risk rather than technology, and being direct when a request is more expensive than it sounds. Several of the client reviews are from founders describing exactly that working relationship.
