Web application with dashboard and data visualization
Web applications

Web apps built to scale

SaaS, dashboards, marketplaces, and internal tools, with a codebase that scales with your product.

Overview

When a website isn't enough anymore

Digital products need architecture, not just pretty surfaces.

MVP

Validate fast

SaaS

Subscription-ready

API

Integration-first

Web applications are digital products with real logic: accounts, data, workflows, billing, integrations. Whether SaaS startup, internal automation tool, or marketplace, the difference from a website is depth and scalability.

I build web apps with Next.js, React, and TypeScript, plus APIs, databases, and cloud services as needed. Focus: an MVP that goes live fast and architecture that grows with you.

No one-off solution that needs a rebuild after six months. Clear modules, clean interfaces, and iterative delivery, with regular releases instead of a monolithic big bang.

Whether Stripe subscriptions, role-based dashboards, file uploads with analysis, or webhook-driven workflows: I combine proven services with tailored logic: performant, maintainable, and documented.

Security, monitoring, and deployment are planned from the start, not when the first paying customer goes live. That keeps your product manageable under load and as requirements grow.

On an intro call we clarify product vision, technical requirements, and a sensible first release, transparent with fixed price or day rate.

“A good product solves a real problem. The tech just shouldn't get in the way.”

Use cases

Typical web app projects

From SaaS MVP to production platform.

01

SaaS & subscription products

Onboarding, billing, feature flags, and multi-tenancy, built from day one so subscriptions and user growth scale cleanly.

02

Internal tools & automation

Replace manual processes with digital workflows, with clear rules, traceability, and interfaces your team actually uses.

03

Marketplaces & platforms

Two- or multi-sided models with profiles, listings, matching, and transaction logic, structured instead of feature sprawl.

04

AI-assisted workflows

PDF analysis, classification, or assistants, embedded in real product flows where they deliver measurable value.

Web application with data model and API architecture
Product & architecture

From MVP to scalable platform

Web apps live on a clear data model, clean APIs, and traceable workflows. Whether user onboarding, payment flow, or admin reporting, every feature needs a solid foundation so extensions don't become a rewrite.

I use modular Next.js architecture, typed APIs, and relational databases with clear migrations. Auth, billing, background jobs, and third-party integrations are planned as solid building blocks, not bolted on later.

The MVP focus stays: go live fast, get real feedback, then iterate. That avoids months of development without market validation and builds a codebase that grows with your product.

Deliverables

What I build in web applications

From prototype to production platform.

01

SaaS products & subscriptions

Multi-tenant architecture, billing, onboarding, and feature flags, planned from the start.

02

Dashboards & admin tools

Data visualization, filters, exports, and management interfaces for your team.

03

Marketplaces & platforms

Two- or multi-sided models with profiles, listings, and transaction logic.

04

Automation & workflows

Internal tools that replace manual processes, with clear rules and traceability.

05

APIs & backend integration

REST, GraphQL, webhooks, and third-party connections, robust and documented.

06

AI features & smart automation

PDF analysis, chat assistants, or classification, where it adds real value.

Process

How we work together

Three steps from first call to shipped result, transparent and without agency overhead.

01

Free intro call

Clarify goals, scope, and timeline, so we know if and how we should work together.

02

Strategy & build

Concept, design, and development in iterations with regular updates.

03

Launch & outcomes

Go-live with performance basics, SEO foundation, and clear next steps.

Common questions about web applications

With a clear MVP: the smallest version that delivers real value to real users. We build iteratively from there.

Depending on the project PostgreSQL with Prisma, Supabase, or similar, always with migrations and a clear data model.

Yes. Code, deployment, and documentation are handed over so your team or another developer can take over seamlessly.

Gladly. Bug fixes, features, and scaling can be agreed as retainer or project-based.

Depends on scope, integrations, and logic complexity. A focused MVP is significantly cheaper than a full version with all modules. After the intro call you'll get a transparent quote.

Typically a few weeks to a few months, depending on scope, integrations, and design depth. We define the smallest sensible release together and iterate from there.
