What I’m studying, why it matters to my work, and the projects and notes connected to it.
These are courses I am enrolled in. Enrollment is separate from course completion or professional certification.Enrollment confirmed Nov 1, 2026. Related projects show adjacent practice; they are not presented as completed course assignments.
Build more reliable Excel tools through reusable macros, clear interfaces, and deliberate error handling.
Extend a workbook automation with input validation, a useful error message, and a documented test case.
A proposed exercise, separate from the work linked above.Deepen the transformation layer: modular SQL models, data tests, lineage, and documentation that make analytics easier to trust.
Create a small source-to-mart dbt model with explicit grain, relationship tests, and documented business definitions.
A proposed exercise, separate from the work linked above.Strengthen orchestration decisions around scheduling, dependencies, retries, backfills, and pipeline observability.
Document a retry and backfill scenario for an existing DAG, including what happens when an upstream source fails.
A proposed exercise, separate from the work linked above.Connect distributed processing fundamentals with practical ingestion and storage choices across cloud data platforms.
Compare a local batch-processing lab with a proposed cloud architecture, including costs, failure modes, and data movement.
A proposed exercise, separate from the work linked above.Understand the operating-system behavior beneath a slow query, a container, or a data-processing workload.
Extend a small process or memory experiment with observations, commands, and a reproducible explanation.
A proposed exercise, separate from the work linked above.Make local data and automation environments easier to run, debug, and hand over to another person.
Review a Compose service for persistent storage, health checks, networking, and clear recovery instructions.
A proposed exercise, separate from the work linked above.Connect data-modeling choices to the database engine: consistency, indexes, concurrency, and query execution.
Compare execution plans before and after an index change, recording the data size and measurement method.
A proposed exercise, separate from the work linked above.Try a tool, topic, instructor, or another subject.
