DeskFlow

IT Helpdesk & Asset Management Platform

A small ServiceNow-style service desk: tickets with a status workflow and SLA timers, a hardware inventory, a Markdown knowledge base with Postgres full-text search, an append-only audit log, and an optional AI assistant that only answers from published articles. Angular front end, async FastAPI back end and a background worker, containerised and deployed on Railway.

• SLA engine: per-priority response/resolution targets, clock paused while Pending, worker flags at-risk and breached tickets
• Single source of truth for SLA rules — API, dashboard, filters and worker can't disagree
• Grounded AI assistant (Claude): retrieves only published articles, cites them, drops answers that cite nothing
• Postgres full-text search (tsvector + GIN) with ranking, stemming, phrases and highlighted snippets

liftpipe

Strength-Training Data Pipeline & Analytics

An end-to-end, free-to-run data pipeline: it ingests Hevy workout exports and Apple Health data, models them with dbt on DuckDB, orchestrates everything as one Dagster asset graph, and serves a static dashboard that queries the marts in the browser with DuckDB-WASM. Visitors can upload their own Hevy CSV and see their own dashboard in seconds.

• Layered dbt models (raw → staging → intermediate → marts) with 75 data tests and unit tests
• One Dagster lineage graph from file to dashboard — every dbt test becomes an asset check
• Idempotent, incremental loads keyed on natural keys and file hashes
• Streaming Apple Health XML parser: 27 MB memory on a 109 MB export vs 1 GB for a full parse
