Devlog: Freelance Project Profit & Rate Estimator - How Pixel Office AI Agents Streamline Freelancer Pricing
The problem of undervaluing one's work is pervasive among freelancers and small agencies. How do you accurately price your services? How do you ensure project profitability while remaining competitive? This often leads to non-data-driven estimates and frustration. At Pixel Office, we decided to tackle this challenge using our AI agents, Jan (the coder) and Klára (the designer), overseen by Martin (QA) and Tomáš (Deployment).
Introducing: Freelance Project Profit & Rate Estimator
We are proud to present our latest widget: the Freelance Project Profit & Rate Estimator. This tool is designed to help freelancers and small agencies accurately estimate project costs, set profitable hourly rates, and generate professional quotes. Users input their desired annual income, operational expenses, billable hours, and project-specific tasks with estimated durations. The tool then calculates a recommended hourly rate and provides a detailed breakdown of project profitability. The free version allows calculation for a single project with basic inputs, while the premium version unlocks advanced features like multi-project management, detailed expense tracking, client-specific rate adjustments, automated 'buffer time' calculations, and the ability to export professional project proposals/quotes as PDF documents or shareable links.

Architecture and Development with AI Agents
Developing such a complex financial tool typically requires weeks of work. Thanks to our agile approach with AI agents, we were able to iterate and deliver a functional MVP in record time.
Klára's Role (AI Designer)
Klára, our AI designer, focused on user experience (UX) and user interface (UI). Her task was to ensure that the data entry process was intuitive and the outputs were clear and understandable. She designed the structure of forms for annual income, expenses, and project tasks, visualizations for the profitability breakdown, and templates for exported PDF proposals. Klára emphasized a clean design that reduces cognitive load and maximizes usability for users who might be encountering similar tools for the first time.
Jan's Role (AI Coder)
Jan, our AI coder, was responsible for implementing the core logic of the tool. He translated Klára's designs into functional code that handles complex financial calculations, data management, and user interface interactions. One of the key challenges was ensuring localization and flexibility for future expansions. Jan elegantly solved multilingual support using an i18n structure.
"When implementing internationalization for this tool, I focused on a robust
i18nobject structure. This allows us to easily add new languages and keep all texts in one place, greatly simplifying maintenance and scaling. By defining all texts, from the title to individual form labels, as key-value pairs for each language, we achieved maximum flexibility without needing to modify application logic for every new translation." – Jan, AI Developer
Below is an example of Jan's code for widget initialization and localization:
const WIDGET_SLUG = "freelance-project-profit-calculator";
const WHATSAPP_NUMBER = "420607450436";
const PIXEL_VENTURES_API = "https://api.pixeloffice.eu/api/pay";
const FREE_USES_LIMIT = 3;
const i18n = {

The Roles of Martin (AI QA Agent) and Tomáš (AI Deployment Specialist)
Martin, our AI QA specialist, played a crucial role in testing the accuracy of calculations and the functionality of all parts of the tool, including validating data inputs and PDF outputs. Thanks to his meticulousness, we identified and fixed potential edge cases. Tomáš, our AI deployment specialist, handled the smooth deployment of the widget to the production environment, ensuring its availability and performance at https://pixeloffice.eu/showcase/demo-webtrh-freelance-project-profit-calculator/, and integrated it into our infrastructure.
Conclusion
The development of the Freelance Project Profit & Rate Estimator is further proof of our AI agents' capabilities to create complex and useful applications with incredible speed and efficiency. By combining Klára's creative design, Jan's precise coding, Martin's thorough testing, and Tomáš's reliable deployment, we were able to deliver a tool that has the potential to truly help freelancers thrive.
