A SaaS product, from the idea to the first paying customers

SaaS means software your customers use in a browser and pay for by subscription. I build the whole thing — including the parts that have nothing to do with your idea and still eat most of the schedule.

What it means

The idea is usually the easy part. Between it and the first paying customer sit accounts and sign-in, password resets, pricing tiers, invoicing, security, deployment and day-to-day operations. None of that is what makes your product worth buying, and all of it has to exist before anyone can buy it.

I have built those pieces repeatedly, including in products of my own. I do not reassemble them from scratch each time, so you get to the part that is genuinely yours sooner.

Frontend, backend and third-party integrations stay in one pair of hands. There is no coordination between suppliers, and nothing falls into the gap between them.

It makes sense when

  • you have a product idea and need it in front of paying customers
  • you want to sell a subscription rather than a one-off licence
  • many customers have to be served from a single deployment
  • you would rather have one partner for design and build than a chain of hand-offs

What you get

  • sign-up, authentication and user roles
  • Stripe subscriptions, pricing tiers and trial periods
  • a customer area where users manage their own account
  • production deployment and an automated CI/CD pipeline
  • integrations the product needs — email, payments, external APIs

How it works

  1. Pin down the product

    Who buys it, what they are paying for, and what the first version has to do before it can be sold at all.

  2. Validate the interface on a prototype

    A clickable prototype of the core flow — sign-up, the main use case, pricing — before any production code is written.

  3. Build the first version

    Accounts, payments and the main scenario as one working whole, deployed so real users can be let in.

  4. Extend it against real usage

    What gets built next follows what customers actually use, not the original wish list.

Where you can see it

Weather InTouch A full-stack, multi-channel weather forecast platform built around proactive alerts and automation rather than passive data display. Weather InTouch pairs a free open-data backbone with a cost-controlled caching layer that deduplicates paid weather-API calls across all users. It runs in production as a B2C web app — live weather cards, official alerts from seven national sources, watchdog automations, an AI weather assistant and Stripe billing — backed by a multilingual marketing site and blog spanning 20 languages. An embeddable white-label widget is built and rolling out, with the native iOS/Android shell (Capacitor) pending store release. FreelancePricing A SaaS platform built for Czech freelancers to manage their entire business workflow in one place. Covers project and client management, AI-assisted price estimation, quote and invoice generation, and a subscription and credits model powered by Stripe. Optimised for the Czech market with CZK currency formatting, ARES business registry lookup, and a bilingual Czech/English UI. Seller Bridge A private SaaS platform that bridges Printify (print-on-demand fulfillment) and global marketplaces, starting with Amazon SP-API and eBay. Operators define Regional Product Templates once and the platform handles variant mapping, parent-child Amazon listings, GTIN exemption workflows, BullMQ-based publishing pipelines, and bidirectional order and fulfillment sync. It is designed around the Amazon Data Protection Policy and is in beta, not yet publicly available.
