SaaS · UX/UI · AI

Design and build web applications that simplify operations and make daily work easier.

I help companies transform outdated applications and websites into intelligent digital products — where AI is the core of the user experience, not a feature bolted on afterwards. Design and implementation stay in one pair of hands: from wireframe and prototype to a deployed application. For Angular 2+ codebases, AI-assisted tooling helps me quickly understand the codebase, implement the right solution, and deliver high-quality results without lengthy manual work.

Your own SaaS product

Sign-up, pricing tiers and Stripe payments

Web apps and client portals

Day-to-day operations in one place

Modernization, not a rewrite

Angular 2+ brought up to date without downtime

AI as the core, not an add-on

Search, forms and assistance inside the product

UX/UI design, not just code

From wireframe to the finished interface

Who I help

The best fit is usually a company building a product of its own, or one that already feels friction in day-to-day operations and needs a practical product partner, not a generic brochure website.

Companies and founders who want their own SaaS product

The friction

The idea exists, but between it and paying customers sit sign-ups, pricing tiers, billing and running costs that quietly sink projects.

What you get

A deployed product that can take paying customers — from MVP onwards.

How I can help

Companies needing a portal or internal app

The friction

Customer requests, internal operations and data live across emails, shared drives and ad-hoc tools.

What you get

One place where every role has its own view and the process has explicit rules.

How I can help

Companies with an Angular 2+ app that blocks progress

The friction

Older Angular codebases become hard to extend, slow to run and expensive to maintain.

What you get

An application you can extend again — without a rewrite and without downtime.

How I can help

Businesses ready to put AI at the center

The friction

A search box on top of an old site no longer cuts it — users expect the product to point them to what they need and walk them through it.

What you get

A product that guides the user, instead of waiting for the right question.

How I can help

What I help companies solve

The offer is intentionally framed around business problems and delivery outcomes, not around the framework list.

SaaS products from idea to paying customers

I build SaaS applications including the parts that usually take the longest: sign-up and authentication, subscriptions and pricing tiers via Stripe, and serving many customers from a single deployment. The same pieces are built into my own products.

What this means
Delivered in:Weather InTouch, FreelancePricing, Seller Bridge

Web applications and client portals

I build interfaces that combine product clarity, application logic and maintainable delivery.

What this means
Delivered in:LingoSnap, ELISA, Rental App

Automated Angular 2+ refactoring

I migrate older Angular 2+ codebases to modern Angular using AI-assisted tooling — quickly understanding the codebase, implementing changes with precision, and delivering results without tedious manual work.

What this means
Delivered in:ELISA, tSM, QMS

AI transformation of existing applications

I turn outdated websites and apps into intelligent products where AI is at the core — smarter information discovery, guided data entry and personalized assistance using Google's latest AI stack.

What this means
Delivered in:LingoSnap, Recut CV, ED Elektro

UX/UI design and prototyping

Before a line of production code is written, the interface is validated on a prototype — wireframes, a clickable prototype and a design system that then holds up in the implementation.

How collaboration usually works

The goal is not to push code fast at any cost. The goal is to arrive at a usable solution with enough clarity to keep momentum.

1

Understand the workflow

We identify where the current friction is, who uses the system and what result actually matters.

2

Choose the right scope

Sometimes the right next step is a prototype, sometimes a narrow first release, sometimes modernization of an existing part.

3

Refine the solution sprint by sprint

Development follows the customer's current priorities. Each sprint validates another set of scenarios and gradually clarifies what the final product should be.

4

Support real usage

Once the application is live, the next step is usually refinement, expansion and ongoing operational support.

Prototype-first delivery

Not sure about the scope yet? Let's start with a prototype.

When the direction still needs validation, the first step is rarely a full build. A focused prototype takes a single workflow, makes it tangible and turns abstract requirements into something the team can actually test.

New SaaS products

A clickable prototype of the core flow — sign-up, the main use case and pricing tiers — before committing to a full build.

Document-heavy operations

PDF data extraction, review and approval workflows, and AI-assisted draft generation over existing documents.

Legacy-system clients

A modern interface over an existing backend, replacing the single most painful workflow before any broader rewrite.

The ED-Elektro redesign runs on this site as a prototype you can walk yourself — real screens, real navigation, no account and no Figma link.
