I'm a Data Platform Architect with 8 years of experience building lakehouse architectures, semantic dimensional models, and AI applications that solve real problems. I've led platform modernizations that reduced development cycles from weeks to days, contributed to 99.9% SLA reliability at scale, and built production RAG systems with LangChain.

My work is guided by a simple principle: technology should improve people's lives. Whether designing data platforms for self-service analytics, building RAG systems for information access, or creating tools for elder care and music education, I focus on practical solutions that create measurable value.

Data Architecture & Platform Leadership

• Designed medallion pattern lakehouses with semantic dimensional models that reduced dashboard development from weeks to days
• Led infrastructure modernization from manual operations to IaC with orchestration pipelines, automated testing, and data quality frameworks
• Built reusable dimensional models enabling self-service analytics across finance, product, and sales teams

AI & Production Systems

• Built production RAG pipelines with LangChain, multiple vector databases (ChromaDB, Pinecone, pgvector, Astra DB), and local LLM integration
• Contributed to 99.9% SLA reliability for platforms serving millions of users through SRE practices and observability work

Leadership & Collaboration

• Led development teams and mentored engineers with a focus on code quality, documentation, and knowledge sharing
• Built developer experience tooling, including CLI tools, unified development environments, and automated quality gates

Data Architecture & AI: Building production-grade data platforms and AI applications. Recent work includes comprehensive lakehouse implementations with medallion architecture, semantic dimensional models for self-service analytics, and RAG systems with LangChain. Experienced with modern orchestration and transformation tools, actively developing expertise in cloud-native lakehouse platforms.

Open Source & Community: Contributing to projects that democratize access to technology and knowledge, including AI agent tooling, language learning applications, and platforms for elder care and music education.

Production RAG System | Python, LangChain, ChromaDB, Vector Databases

Complete RAG pipeline for Finnish immigration information, built with production engineering practices (comprehensive tests, type checking, automated quality gates). Demonstrates end-to-end AI application development from web crawling through semantic search to an interactive chatbot.

Lightweight Format for AI Agent Capabilities | Markdown, YAML, AI Frameworks

Collection of skills in the Agent Skills format, an open format for extending AI agent capabilities with specialized knowledge and workflows. Demonstrates practical approaches to making AI agents more capable and context-aware.

AI-Powered Language Learning | Python, AI/ML Frameworks

Interactive web application combining AI with structured lessons to create immersive, context-specific language learning experiences for realistic scenario practice.

Technical Development Tool | Flutter, Dart, MIDI

Mobile application for piano students and teachers focusing on technical development through interactive exercises, real-time feedback, and progress tracking. Built with precise MIDI integration to complement repertoire practice with targeted exercises for coordination and muscle memory.

Elder Care Ecosystem | Vue.js, Meteor.js, Django, MongoDB, Plotly.js

Comprehensive toolkit for elder care that makes quality-of-life activities visible and measurable, built from real-world insights gathered through volunteer work at care facilities in Tampere, Finland.

Components:

• Wellbeing: Activity logging and visualization for resident engagement tracking
• Caregiving: Insights platform for coordinators across multiple care levels
• Companionship: Tools for promoting meaningful social connections

Personal Fitness Tracker | Svelte, SvelteKit, TailwindCSS

Open-source workout tracker that helps users visualize progress and maintain consistent exercise habits through simple, effective logging.

I'm actively developing expertise in:

• Cloud-Native Lakehouse Platforms: Exploring Databricks, Microsoft Fabric, and Snowflake architectures
• Advanced Dimensional Modeling: Deepening expertise in semantic layer patterns and metric frameworks
• AI/ML Engineering: Expanding RAG patterns, LLM fine-tuning, and production ML deployment practices
• Data Quality & Governance: Advanced testing frameworks and governance patterns for enterprise data platforms

I believe effective technology starts with understanding real needs. My approach combines:

• Architectural Thinking: Focus on patterns and principles that transfer across platforms rather than vendor-specific implementations
• Technical Excellence: Production-grade engineering with testing, type checking, and maintainable code
• Practical Solutions: Tools that solve actual problems, not technology for its own sake
• Knowledge Sharing: Strong documentation, mentoring, and building systems that help others succeed
• Continuous Learning: Honest about what I know and what I'm developing, with demonstrated ability to learn quickly

Beyond professional work, I volunteer as an English teacher and pianist at Mummon Kammari elder care facility in Tampere, serve as a steward for Tampere Friends (Quakers), and create Creative Commons-licensed music available at brylie.music.

I'm interested in building data platforms and AI applications that create a meaningful impact. If you're working on problems in healthcare, education, sustainability, or other areas with real social value, I'd be glad to connect.
