Custom web application development
A custom web application when your workflow is the product, not an edge case.
I design and build web applications for problems that do not fit comfortably inside a theme or generic platform. The decision to go custom is made carefully: the workflow must justify owning the product model, interface, data rules, testing, deployment, and future maintenance.
Custom is a responsibility, not a badge
A blank repository offers freedom, but it also removes the defaults a mature platform provides. I compare the workflow with established products before recommending a custom build. When custom is the right call, the scope includes not only visible screens but also identity, permissions, data integrity, failure states, operations, and the cost of changing the system later.
Product decisions and engineering stay connected
The data model shapes the interface, and the interface reveals gaps in the workflow. I work across those layers instead of freezing one before learning from the other. That is especially useful for a founder or small team that needs direct technical judgment while a product is still becoming precise.
Durability lives below the polished screen
The browser is only one participant in a reliable application. Authorization, validation, scoring or business rules, scheduled work, and observability must live in the layer that can enforce them. Tests and deployment behavior are treated as product work because users experience the consequences when either is missing.
Custom web application development
A complete application boundary
The exact stack follows the product, but the engagement accounts for the full path from workflow to a maintainable production system.
Application architecture
Clear boundaries across interface, server behavior, data model, permissions, integrations, and operational responsibilities.
Product interface development
Responsive workflows and stateful interactions built in Svelte, React, Vue, or the frontend that best fits the system.
Backend and data rules
Laravel, Postgres, or Supabase implementation with validation and critical rules enforced outside the browser.
Testing and release systems
Automated coverage, deployment checks, recovery paths, and documentation proportionate to the application’s risk.

Two public products, two different application shapes
Sítio Raiz and ReadRivals demonstrate full-product work without relying on a confidential client result.
Sítio Raiz: commerce and operations in Laravel
Sítio Raiz is a current Laravel application for a local farming family, covering the path from early design and data decisions through storefront operation, tests, analytics, search work, and continued feature development.
ReadRivals: realtime product rules in Postgres
ReadRivals uses SvelteKit and Supabase for a live social reading product. Realtime rooms reach the interface, while scoring, row-level security, scheduled work, and automated database coverage live in Postgres.
How a custom application earns its architecture
The product is reduced to testable decisions before the system accumulates infrastructure it does not need.
Define the workflow
We identify the users, decisions, data, permissions, edge cases, and operating responsibilities that make the product distinct.
Choose the smallest sound system
I compare platform and custom options, then define an architecture that supports the verified workflow without speculative layers.
Build in verifiable slices
Interface, business rules, data protection, tests, and deployment evolve together in end-to-end increments that can be reviewed.
Custom application questions
These are the decisions that determine whether owning custom software is justified.
How do I know whether I need a custom application?
Start with the workflow, not the desired stack. If a maintained platform supports the important behavior without fighting the operating model, it may be the better choice. Custom development becomes reasonable when the distinctive workflow is central enough to justify owning its rules and maintenance.
Can you help define the product before building?
Yes. I can turn an operating problem into explicit users, states, rules, data, dependencies, and acceptance criteria. That definition is engineering work: it exposes uncertainty early and makes it possible to choose a smaller architecture or a staged release with honest boundaries.
Which technologies do you use?
My current public work includes SvelteKit, Laravel, Postgres, and Supabase, and my broader experience includes React and Vue. The choice follows the product, team, hosting, and maintenance needs rather than a promise to use every technology on every project.
What happens after the first release?
The first release should establish a maintainable path, not end the relationship between product and engineering. Documentation, automated checks, deployment behavior, and a visible backlog make future changes deliberate. Ongoing work can then be scoped from real usage rather than launch assumptions.
Start with the workflow
Describe the job your product must do before naming the stack.
Tell me who uses it, what decision they need to make, and why existing tools do not fit. That is enough for the first technical question.
