Haven: An End-to-End Encrypted Therapeutic Journal

A therapeutic journal connecting patients and psychologists between sessions, combining psychometrics and data analysis for continuous, patient-free monitoring.

I built a behavioral analysis engine using Supabase for data management and secure authentication (RLS). I implemented exponential moving-average algorithms over context, intensity, and timestamp records, letting each user define their own emotional dictionary. The system translates that subjectivity into a real clinical chart — without ever having access to the plaintext data.

Dimensional Modeling: Data Architecture

Evolved the data architecture from monolithic tables to dimensional modeling (Kimball), focused on business traceability.

I restructured the data model from single tables into a dimensional design centered on business domains, such as Credit and Resource flows. This transition drastically simplified maintaining work history and building strategic dashboards for the business area, turning complex data into an intuitive structure that reflects operational reality and speeds up decision-making.

Implemented modular layers enabling precise history and fast dashboard creation for the business area.

Operational Management Hub

Consolidated complex indicators into a single unified view to speed up strategic decision-making.

I restructured the analysis flow by consolidating multiple scattered dashboards into a single, intuitive interface. Using dimensional modeling (Kimball), I simplified data access so managers could spot trends instantly, drastically cutting cognitive load and operational time.

Cut KPI review time from 15+ min to <2 min (-86%)

Conversion Tracking System

Automated the conversion pipeline with real-time updates and a granular view of performance.

I built a system to reflect product conversions immediately after the action. Previously there was a 15-day delay before an update; now visibility is daily, allowing granular tracking by manager, branch, city, and segment with always-current data.

Structuring Product Discovery Processes

Designed discovery and prioritization frameworks to align business needs with user experience.

I put together complete methodological frameworks to guide decision-making in digital products. The process includes selecting and applying tools like PAINstorming to identify pain points, Behavior Gap to analyze flows, and MoSCoW to prioritize features, ensuring development is always driven by evidence and real user needs.

Developed complete methodological playbooks for strategic alignment.

Bulk Update System

An automation engine that processes and validates complex spreadsheets for batch updates to legacy databases.

A tool that eliminated the need to retype operational information, validating data in the browser itself before server-side processing to prevent transaction failures.
