An MVP needs an end-to-end owner
Translate a product brief into a scoped architecture, working application, deployment, and clear next-stage roadmap.
Full-stack SaaS development
SaaS products built from workflow and data model through deployment
I design and build focused SaaS products where frontend, backend, permissions, billing, and operations need to work as one system. The result is a maintainable production foundation, not a disconnected collection of screens and endpoints.
Problems I solve
Where I can make the biggest difference
Roles and tenant boundaries are unclear
Model organizations, memberships, permissions, and data isolation on the server before sensitive information reaches the UI.
The product has outgrown prototype code
Stabilize schemas, APIs, authentication, background work, errors, and deployment without rebuilding blindly.
Deliverables
What you can bring me in to deliver
- Responsive product interface and reusable design system
- Authentication, role-based access, organizations, and multi-tenancy
- REST APIs, database schemas, validation, and background workflows
- Payments, subscriptions, email, uploads, and third-party integrations
- Admin tooling, observability, error handling, and deployment
- Technical documentation and post-launch iteration plan
Development process
Clear decisions, reviewable progress, fewer surprises
- 01
Scope the product core
Identify the smallest complete workflow that creates value and the technical risks that must be solved early.
- 02
Model data and access
Design schemas, tenant boundaries, roles, API contracts, and failure states before UI implementation spreads assumptions.
- 03
Build vertical slices
Deliver complete workflows across interface, API, database, and integrations so progress is testable throughout.
- 04
Harden and launch
Verify permissions, responsive behavior, performance, deployment, monitoring, backups, and operational handover.

Personal Product
WorkNavo — Multi-Tenant Client Operations Platform
A multi-tenant SaaS built on the MERN stack: React 19 + Vite frontend, Express 5 API, MongoDB with Mongoose. Users belong to multiple organizations with role-based permissions (Admin, PM, Finance, Member, Viewer), track time with live timers, and generate PDF reports, invoices, and CSV exports — all scoped so members only see their own data.

Reppod — Two-Sided Coaching SaaS
A two-sided SaaS for personal trainers and their clients: drag-and-drop workout builders, invite-based two-sided auth, Cloudinary video uploads, engagement analytics, in-app messaging, and AI-generated workout plans. Built solo end-to-end on Next.js 16 and MongoDB to demonstrate real-product patterns, not a demo app.

SecurePay — Multi-Currency Digital Wallet
A digital wallet MVP built as six independent FastAPI microservices (gateway, user, wallet, transaction, fraud, notification) behind Docker Compose, with Postgres, Redis, and RabbitMQ. Users verify by email OTP, hold balances in USD/EUR/GBP/PKR, and send money across currencies at live exchange rates, screened for fraud in real time. The React Native app handles multi-currency statements, beneficiaries, and PDF exports. Built and tested locally as a full-stack exercise — not deployed to production.

“Farhan helped us turn our designs into a practical, user-friendly product. His full-stack experience was clear in the quality of the frontend, backend, and overall system structure, exactly what a brand-first studio like ours needs from a development partner.”

FAQ
Questions about full-stack saas development
Can you build both the frontend and backend?
Yes. I handle product UI, APIs, databases, authentication, integrations, deployment, and the contracts connecting those layers.
Do you work with existing SaaS codebases?
Yes. I can audit an existing application, define a staged stabilization plan, and deliver features without forcing an unnecessary rewrite.
Which stack do you recommend?
The choice follows the product constraints. I commonly use Next.js or React, Node.js, MongoDB or PostgreSQL, and introduce separate services only when they solve a real operational need.
