About Me
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.
Based in Finland, I combine technical expertise with community service. Beyond professional work, I volunteer as an English teacher and pianist at Mummon Kammari elder care facility, serve as a steward for Tampere Friends (Quakers), and create Creative Commons-licensed music. My work focuses on practical solutions that create measurable value for the communities they serve.
Data Platform Engineering
I specialize in building lakehouse architectures with medallion patterns, semantic dimensional models for self-service analytics, and modern orchestration pipelines. Recent work includes comprehensive platform modernizations using Apache Airflow and dbt, reducing dashboard development time through reusable dimensional models and automated data quality frameworks.
Professional highlights: Designed medallion lakehouse architectures, built reusable semantic layers, led infrastructure modernization from manual operations to IaC, contributed to 99.9% SLA reliability for platforms serving millions of users.
AI & ML Applications
I build production-grade AI applications with RAG (Retrieval Augmented Generation) architecture. Projects include complete pipelines from web crawling through semantic search to interactive chatbot interfaces, with emphasis on privacy-focused local inference and production engineering practices.
Featured project: Tapio, a complete RAG system for Finnish immigration information with LangChain framework, multi-database support, and local LLM integration using Ollama.
Cloud Platforms & Infrastructure
Experience with GCP and AWS cloud platforms, infrastructure-as-code with Terraform, and container orchestration. Currently developing Azure expertise with focus on cloud-native lakehouse platforms like Databricks and Microsoft Fabric.
Web Development
Full-stack development with Python frameworks and modern JavaScript libraries. Experience building content management systems, API platforms, and interactive web applications for nonprofits and community organizations.
Featured projects: Western Friend (Wagtail CMS for Quaker publication), GeriLife (elder care wellbeing platform), Piano Fitness (MIDI-connected practice app).
Musical Practice
I create ambient and neoclassical piano music under Creative Commons licensing, with around seven albums released to date. My music focuses on healing and community connection, performed at elder care centers and available across multiple platforms. I'm transitioning professionally from "Brylie Christopher Oxley" to "Brylie Christopher" for better discoverability.
Weekly performances at Mummon Kammari elder care facility, leading English friendship groups and providing musical accompaniment for singing sessions.
Community Service
Mummon Kammari (Grandmother's Chamber)
Volunteer English teacher and musician at elder care drop in center. Lead English-language friendship groups and provide piano/guitar accompaniment for weekly singing sessions, creating community connections through music and language.
Tampere Friends (Quakers)
Steward for Tampere Friends worship group with 20 years of faith community experience. Coordinate community activities and facility management, supporting Quaker values of simplicity, integrity, community, and equality.
GeriLife (2015-2025)
Co-founded and developed wellbeing visualization platform for elder care communities in Tampere, contributing to improved quality of service through data-driven insights from individual resident tracking to system-wide analytics.
Approach & Values
My work is guided by a simple principle: technology should improve people's lives. I focus on practical solutions that create measurable value, whether designing data platforms for self-service analytics, building RAG systems for information access, or creating tools for elder care and music education.
- 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
- Knowledge Sharing: Strong documentation, mentoring, and building systems that help others succeed
- Community Focus: Drawn to work that creates tangible impact in healthcare, education, sustainability, or other areas with real social value
Let's Connect
I'm interested in roles where I can build data platforms and AI applications that create 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.
