My Journey
Spiriwors — Frontend (PRANA)
PRANA · spiriwors.com
Spiriwors is a PRANA project where the creative direction had to feel just as intentional in the browser as on paper. I owned the frontend: shaping a cohesive, responsive experience with Next.js, React, TypeScript, and Tailwind CSS, and keeping interactions snappy as we iterated. As the frontend developer, my impact was in translation—turning stakeholder and artistic feedback into reusable components, solid responsive layouts, and a performance-minded architecture that reduced rework and made the UI easier to extend without rewiring the whole app.

Recent Projects
A selection of my most outstanding works in data science and software development
Fullstack web application for a veterinary clinic, featuring an email call-to-action, AI-powered chatbot, marketplace, appointment scheduling, veterinarian CRUD, client CRUD, pet CRUD, treatment sales, and an admin dashboard for full system control and real-time clinic insights.
Planifika is a DrimSoft web platform for educational institutions: centralized project management with planning, monitoring, reporting, and RBAC. I rotated across Scrum, Product Owner, development, QA, and DevOps—shipping from backlog clarity to production. Architecture: microservices behind an API gateway, REST APIs with JWT, Docker, and GitHub Actions CI/CD. Quality and reliability drew on JUnit, Selenium, Postman/Newman, JMeter, and ISO 25010 (performance, scalability, security, maintainability).
Console-based application developed for a Data Structures course to support the board game Scrabble. It implements advanced data structures for word search, validation, scoring, and generating strategic suggestions.
Android mobile app designed to connect pet owners with reliable dog walkers nearby. PetStep addresses time constraints, low visibility of available walkers, and security concerns by offering real-time monitoring and seamless communication.
Interactive project developed with Observable to analyze Spotify's data governance and business model. It explores industry trends, challenges, and opportunities, providing recommendations to improve strategy and data practices.
Comprehensive analysis of Apple's financial, sales, and customer data to identify trends, strategic opportunities, and market positioning.
Developed a predictive analysis model to compare energy consumption trends between G7 and BRICS countries using Bayesian Structural Time Series (BSTS). The work centered on modeling temporal patterns and surfacing structural differences in energy behavior across major economies. Implemented in R, the approach supported probabilistic forecasting and scenario analysis. Along the way it deepened my practice with time series data, statistical modeling, and translating results into real-world interpretation.
Frontend puzzle game built with Angular 16 where players connect pairs of numbers without overlapping paths. Includes an AI-based auto-solver and statistical analysis of solutions.
Developed a custom TFTP server in Python, implementing read/write requests, error handling, and file directory management over UDP.
Personal Projects
Side projects I ship end-to-end—frontend tooling, data on the wire, and polished UX.
A client-side TypeScript tool that parses WhatsApp-exported `.txt` chats and renders them as an interactive, WhatsApp-style thread—bubble layout, colors, avatars with initials, and drag-and-drop or click-to-upload. The parser turns raw lines into structured messages you can scan for behavioral and communication patterns; everything runs in the browser with React 19 and Vite 7, no backend required.
A movie web app built on The Movie Database (TMDb): real-time search, 1–5 star ratings, optional text reviews, a personal watchlist, and recommendations informed by what you save—plus light/dark themes and English/Spanish UI. React 19 on the frontend with Supabase handling profiles, preferences, watchlist, and stored reviews.
