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.

SaaS & subscription products

01

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

Internal tools & automation

02

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

Marketplaces & platforms

03

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

AI-assisted workflows

04

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.
