Product and system architecture
Turn workflows, roles, data, integrations, and business constraints into a practical implementation plan.

Full-Stack Next.js & Node.js Software Engineer
I build complete web products where the interface, server logic, data model, authentication, payments, and external services work as one system. I help startups and growing businesses move from an idea or fragile prototype to a production application using Next.js, Node.js, TypeScript, PostgreSQL, and Supabase.
Problems this engagement is built to solve
The scope starts from the product problem—not a prepackaged list of technologies.
- Frontend and backend work is split across disconnected implementations
- The prototype cannot safely support real users or business operations
- Authentication, permissions, and data ownership are unclear
- APIs, webhooks, payments, and third-party services drift out of sync
- Product changes require risky edits across an undocumented data model
- The team needs production delivery rather than another isolated demo
What you should leave with
- A coherent product architecture from interface to database
- Typed contracts across Next.js, Node.js, and external integrations
- Secure authentication, authorization, and server-side operations
- Maintainable PostgreSQL or Supabase data workflows
- A deployed product with documented operational boundaries
What the work includes
A focused engagement covers the decisions, implementation, and handoff needed to solve the problem cleanly.
Frontend product experience
Build responsive Next.js interfaces with accessible interactions, useful loading states, and clear product feedback.
Node.js backend and data
Implement typed server logic, APIs, webhooks, PostgreSQL or Supabase data access, authentication, and permissions.
Integration and production handoff
Connect payments and third-party services, verify critical paths, deploy, and document the system for continued development.
A clear path from diagnosis to delivery
You see what is being changed, why it matters, and how the result is verified.
- 01
Define the product
Clarify users, workflows, roles, critical data, integrations, and the smallest valuable release.
- 02
Design the system
Set boundaries between UI, server operations, database rules, background work, and external services.
- 03
Build end to end
Deliver complete vertical slices so each feature works from the interface through the backend and data layer.
- 04
Verify and launch
Test permissions, failure paths, responsive behavior, integrations, and deployment before handoff.

A logistics product connecting booking, parcel tracking, proof-of-delivery messaging, business enquiries, and operational workflows.
Frequently asked questions
Practical answers before we define the project scope.
- What does full-stack software development include?
- It covers the parts required to deliver a working product: the user interface, server-side logic, APIs, database structure, authentication, permissions, integrations, deployment, and the failure states connecting them.
- Can you build both the Next.js frontend and Node.js backend?
- Yes. I build Next.js and React interfaces alongside Node.js server logic, typed APIs, webhooks, PostgreSQL or Supabase data access, authentication, and external integrations.
- Do you work on existing applications or only new products?
- Both. I can build a new product, extend an existing application, replace a fragile integration, or take ownership of a focused frontend-to-backend workflow.
- Can you work with an existing product team?
- Yes. I can own a full-stack feature, collaborate through reviewable changes, and document architecture and operational decisions for the rest of the team.
