+# Portfolio Bio Content
+
+**Version**: 2.0
+**Last Updated**: January 2026
+**Purpose**: Content source for `portfolio_app/pages/home.py`
+
+---
+
+## Document Context
+
+| Attribute | Value |
+|-----------|-------|
+| **Parent Document** | `portfolio_project_plan_v5.md` |
+| **Role** | Bio content and social links for landing page |
+| **Consumed By** | `portfolio_app/pages/home.py` |
+
+---
+
+## Headline
+
+**Primary**: Leo | Data Engineer & Analytics Developer
+
+**Tagline**: I build data infrastructure that actually gets used.
+
+---
+
+## Professional Summary
+
+Over the past 5 years, I've designed and evolved an enterprise analytics platform from scratch—now processing 1B+ rows across 21 tables with Python-based ETL pipelines and dbt-style SQL transformations. The result: 40% efficiency gains, 30% reduction in call abandon rates, and dashboards that executives actually open.
+
+My approach: dimensional modeling (star schema), layered transformations (staging → intermediate → marts), and automation that eliminates manual work. I've built everything from self-service analytics portals to OCR-powered receipt processing systems.
+
+Currently at Summitt Energy supporting multi-market operations across Canada and 8 US states. Previously cut my teeth on IT infrastructure projects at Petrobras (Fortune 500) and the Project Management Institute.
+
+---
+
+## Tech Stack
+
+| Category | Technologies |
+|----------|--------------|
+| **Languages** | Python, SQL |
+| **Data Processing** | Pandas, SQLAlchemy, FastAPI |
+| **Databases** | PostgreSQL, MSSQL |
+| **Visualization** | Power BI, Plotly, Dash |
+| **Patterns** | dbt, dimensional modeling, star schema |
+| **Other** | Genesys Cloud |
+
+**Display Format** (for landing page):
+```
+Python (Pandas, SQLAlchemy, FastAPI) • SQL (MSSQL, PostgreSQL) • Power BI • Plotly/Dash • Genesys Cloud • dbt patterns
+```
+
+---
+
+## Side Project
+
+**Bandit Labs** — Building automation and AI tooling for small businesses.
+
+*Note: Keep this brief on portfolio; link only if separate landing page exists.*
+
+---
+
+## Social Links
+
+| Platform | URL | Icon |
+|----------|-----|------|
+| **LinkedIn** | `https://linkedin.com/in/[USERNAME]` | `lucide-react: Linkedin` |
+| **GitHub** | `https://github.com/[USERNAME]` | `lucide-react: Github` |
+
+> **TODO**: Replace `[USERNAME]` placeholders with actual URLs before bio page launch.
+
+---
+
+## Availability Statement
+
+Open to **Senior Data Analyst**, **Analytics Engineer**, and **BI Developer** opportunities in Toronto or remote.
+
+---
+
+## Portfolio Projects Section
+
+*Dynamically populated based on deployed projects.*
+
+| Project | Status | Link |
+|---------|--------|------|
+| Toronto Housing Dashboard | In Development | `/toronto` |
+| Energy Pricing Analysis | Planned | `/energy` |
+
+**Display Logic**:
+- Show only projects with `status = deployed`
+- "In Development" projects can show as coming soon or be hidden (user preference)
+
+---
+
+## Implementation Notes
+
+### Content Hierarchy for `home.py`
+
+```
+1. Name + Tagline (hero section)
+2. Professional Summary (2-3 paragraphs)
+3. Tech Stack (horizontal chips or inline list)
+4. Portfolio Projects (cards linking to dashboards)
+5. Social Links (icon buttons)
+6. Availability statement (subtle, bottom)
+```
+
+### Styling Recommendations
+
+- Clean, minimal — let the projects speak
+- Dark/light mode support via dash-mantine-components theme
+- No headshot required (optional)
+- Mobile-responsive layout
+
+### Content Updates
+
+When updating bio content:
+1. Edit this document
+2. Update `home.py` to reflect changes
+3. Redeploy
+
+---
+
+## Related Documents
+
+| Document | Relationship |
+|----------|--------------|
+| `portfolio_project_plan_v5.md` | Parent — references this for bio content |
+| `portfolio_app/pages/home.py` | Consumer — implements this content |

+abandon rates, and dashboards that executives actually open.
+
+My approach: dimensional modeling (star schema), layered transformations
+(staging → intermediate → marts), and automation that eliminates manual work.
+I've built everything from self-service analytics portals to OCR-powered receipt processing systems.
