Role Responsibilities — Data Engineer and Analytics Engineer building end-to-end automotive time-series pipelines: ingestion, transformation, and cloud integration moving on-premises measurement data (ASAM MDF/MF4 and other formats) into Microsoft Azure and Azure Databricks as queryable Delta tables. Works primarily with Python, SQL, Azure, Databricks, and Delta Lake. Work languages: Python, SQL, C#. 2. V.O.L.T.S Table Generator (Python, sole builder) — on-prem processor turning 500,000+ logger files into one cloud-queryable dataset: 262,000+ signals stored at 10 Hz on global timestamps; custom three-tier resampling (unified-timestamp and per-source methods, outage nulling, no upsampling); statistical duplicate-signal filtering (dataset size, sentinel counts, variance, start time); five export engines behind one setting with an ordered fallback ladder plus RAM-based auto routing and benchmarking; memory-aware parallel workers and distributed multi-server coordination (heartbeats, task queue, live dashboard); schema-unified Parquet with a full metadata family (attributes, lookups, lineage, load history); batch and steady-state processing modes; containers for Windows and Linux. 3. File Converter (Python, sole builder) — general-purpose converter started as a side project and adopted company-wide: reads around 30 input formats and exports 24, with content-sniffed routing, multi-route legacy-format decoding, vendor-tool bridges, frame-based decoding via industry database files, merge/align/cut preprocessors, the same resampling and filtering core, dual export routes per format, a full desktop GUI with profiles for non-technical users, a distributable binary with a multi-language installer, CLI automation, and containers. Serves as the converter backbone inside the V.O.L.T.S pipeline above. ## Personal/open-source projects (most recent first — see https://github.com/bdwandry?tab=repositories) 1.
