Apotelesma: End-to-End SaaS Web Application
Apotelesma is a browser-based SaaS application designed for professional astrologers and advanced students of traditional astrology. The goal of the project was to replace fragmented desktop tools and manual workflows with a single, modern platform that supports advanced chart analysis through an intuitive and responsive web interface.
I designed and developed the application from concept to production, taking responsibility for every stage of the project. This included product planning, UX/UI design, front-end development, back-end integration, authentication, database architecture, deployment, and ongoing feature development. The project required balancing a complex domain with an interface that remains approachable and efficient for everyday use.
One of the biggest challenges was translating highly specialized astrological techniques into a structured digital workflow. The platform includes client management, natal chart analysis, annual profections, solar returns, transits, primary directions, zodiacal distributions, traditional dignities, investigations, and note-taking tools. Rather than presenting isolated calculations, the application guides users through an organised analysis process, allowing them to collect evidence, record observations, and build complete chart interpretations within the same workspace.
From a technical perspective, the application combines a React and TypeScript front end with Supabase for authentication, database management, and cloud services. Throughout development I used AI-assisted workflows with Lovable, Claude, and ChatGPT to accelerate implementation while retaining full responsibility for the architecture, product direction, feature design, testing, and validation. Developing the calculation engine also required extensive research and validation against historical sources and established astrology software to ensure mathematical accuracy.
Apotelesma continues to evolve through ongoing development and user feedback, with new features and workflow improvements being added on a regular basis. The project demonstrates my ability to take a technically demanding idea from initial concept to a fully deployed SaaS application while managing both the product vision and the engineering behind it.

A multi-step patient intake and booking flow built for dental clinics, designed to increase conversion while collecting meaningful, structured patient data upfront. Instead of a generic contact form, patients are guided through a clear, low-friction sequence — reason for visit, urgency, location, and contact preferences — so clinics receive qualified, actionable leads instead of vague inquiries. Clean progress tracking, conditional logic, and a polished, professional UI throughout.

Apotelesma is a professional workspace for chart analysis, built entirely solo — from a real astronomical calculation engine to a fully custom, interactive UI. It connects multiple analytical techniques into one continuous workflow instead of treating them as separate, disconnected tools, with live data panels, saved states, and a system for organizing findings per client. Architected, designed, and shipped end to end. Live at apotelesma.org (http://apotelesma.org).
