Things I've built

High-scale Discord bot ecosystem for the MMORPG Tibia, recognized as a Promoted Fansite by the game’s developers and listed on the official Tibia website. Used in more than 17,000 servers worldwide.

• Supports 6,000 monthly active users and handles roughly 114,000 command requests per month.
• Designed data ingestion and processing services that built historical datasets with more than 100 million records across player activity and game events.
• Operates real-time notification and account-linked insight workflows for an active multiplayer game community.
• Migrated the platform from Python to Kotlin and consolidated it into a monorepo, improving maintainability through static typing and a more unified service architecture.
• Built automated GitLab CI/CD pipelines to test, package, and deploy Dockerized services to a self-managed Ubuntu VDS.
• Implemented observability with Prometheus, Grafana, and Metabase to monitor reliability, performance, and long-term platform health.

Designed the backend for an on-demand healthcare platform connecting patients and doctors, with payment, geospatial, and notification integrations.

• Designed and implemented the HTTP backend used by both iOS and Android clients.
• Built a PostgreSQL/PostGIS data model to support geospatial matching, service history, ratings, and core platform workflows.
• Integrated Stripe Connect to support payment flows between patients and doctors inside the product.
• Implemented Google Maps services for geocoding and travel-time estimation as part of the dispatch and discovery flow.
• Configured Firebase Cloud Messaging for real-time server-to-mobile notifications.
• Owned deployment architecture on a VPS using Docker Compose for both application and database services.

Took over an existing car insurance quotation platform and stabilized delivery while improving maintainability.

• Integrated third-party APIs for geocoding and quote generation, expanding the platform's quoting capabilities.
• Designed application and database models for users, quotations, and policy records.
• Extended the admin panel with operational tooling for managing users, quotations, and issued policies.
• Delivered customer-facing quote forms while improving the reliability of the underlying data flow.
• Standardized frontend code and CSS structure, reducing maintenance overhead in a previously inconsistent codebase.

Python library for scraping and deserializing Tibia.com data, extracted from NabBot into a reusable standalone package.

• Published on PyPI and GitHub with full documentation on Read the Docs and a Dockerized API server for quick deployment.
• Reached 40+ GitHub stars and averages about 350 monthly downloads, with adoption beyond the original parent project.
• Designed strongly typed models and a client API that standardized access to scraped game data.
• Maintained more than 90% test coverage, preserving reliability as upstream HTML structures changed.
• Continues in active maintenance with compatibility fixes for site changes.

Python tool that ingests TibiaWiki articles via the MediaWiki API and converts them into a structured SQLite database.

• Published on PyPI and GitHub with documentation built in MkDocs; also provides a Docker script for quick setup.
• Reached 30+ GitHub stars and averages 100 monthly downloads, with community contributions alongside solo development.
• Processes thousands of TibiaWiki articles into structured data, enabling developers to query and analyze content directly from a relational database.
• Maintained as a stable project, still synchronized with TibiaWiki updates.

Kotlin JVM library for parsing Tibia.com content, developed during NabBot’s migration from Python to Kotlin and now powering NabBot in production.

• Published on Maven Central, available for integration by other developers.
• Provides strongly typed models and a Ktor-based client for reliable website parsing.
• Handles ~2,500 requests per minute in production through NabBot.
• Maintains 90%+ test coverage and automated builds with GitHub Actions and Docker.
• Actively maintained with ongoing fixes for upstream site changes.

Side project developed with a small team as a two-sided job marketplace app.

• Built a native Android application with geolocation services to match users offering and requesting odd jobs.
• Migrated the codebase from Java to Kotlin during Android’s adoption of Kotlin as an official language, improving readability and maintainability.
• Integrated Firebase Messaging Service for job notifications and progress tracking.
• Implemented Google authentication using Firebase for account management.
• Designed and connected the app to a SQL database for storing user and job data.
• Introduced GitLab CI/CD pipelines to automatically generate APK builds, enabling the team to test and share updated versions throughout development.

Android Things library for the RC522 RFID module, providing communication between the device and compatible tags.

• Implemented complete functionality for card authentication, block read/write, and memory operations (increase, decrease, transfer).
• Published to Bintray as one of my first publicly released libraries.
• Reached 45 GitHub stars and received community use before Android Things was discontinued.
• Now archived, but remains available on GitHub as a stable reference.
