Planning a story takes a lot of work and time. Draftical gives you the tools to create your first draft scene by scene, all safely secured in the cloud.

Draftical is a React front-end, Node.js (Express) back-end web app providing scene-based story drafting for authors. The app is Dockerized and hosted with the use of Docker Compose. It also includes a connected Stripe account to process users' payments and subscriptions.

Together with the customer's development team, my team and I created a complete relaunch and overhaul of an old ERP solution. I was the main architect of the front end and communicated a lot with the client's team, our developers, and the designers responsible for the project.

I also communicate frequently with the client's management team to discuss meeting deadlines and how the project was moving forward.

The front end was a complex React app, using Redux and Redux-Saga for state management and communicating with the back end. The client had developed a complex metadata structure on the back end to tell the front end what it should show on render. We fetched the data efficiently and displayed all the business insights as wished.

AWS Rest, Lambda, and Cognito stack, landing page, customer portal, and CMS customization for an electricity provider.

I was the technical lead, communicating with our agencies' designers and client product owner to develop the app. I architected the front-end stack and set up and developed a complex AWS stack using Cognito, API Gateway, DynamoDB, and Lambda functions to talk to a third-party system providing the energy tariff and order process data and endpoints.

In this project, as the sole developer, I built a simple front end for a German supermarket chain to compare their sales regions. We obtained a day's worth of sales data to show their respective regions to test the system. The client could see how sales went for each region and adjust their marketing efforts to maximize profits accordingly.

The app was completed in React, using Leaflet.js to render a map of the client's sales regions. Using a communicated color system, I showed how markets performed and where optimization would make sense for the customer.
