The real work is upstream — data quality, lineage, contracts, and governance that make AI possible without making it dangerous.Sun, 05 Apr 2026 00:00:00 GMThttps://udaykapur.com/writing/designing-data-platform-architecture-for-the-team-you-will-have-in-two-years/https://udaykapur.com/writing/designing-data-platform-architecture-for-the-team-you-will-have-in-two-years/Most data platform architecture is designed for the team that exists today. That's a problem, because in two years the team will be bigger, the requirements will be different, and the shortcuts will be load-bearing.Sat, 22 Nov 2025 00:00:00 GMThttps://udaykapur.com/writing/why-your-dbt-project-will-become-unmaintainable/https://udaykapur.com/writing/why-your-dbt-project-will-become-unmaintainable/dbt makes it easy to start a data transformation layer. It also makes it easy to build one that nobody can reason about six months later. These are the patterns that rot.Sun, 15 Jun 2025 00:00:00 GMThttps://udaykapur.com/writing/test-harnesses-for-data-pipelines/https://udaykapur.com/writing/test-harnesses-for-data-pipelines/Testing data pipelines isn't like testing application code. The inputs are messy, the outputs are probabilistic, and the infrastructure is expensive. Here's how to build test harnesses that work.Sat, 11 Jan 2025 00:00:00 GMThttps://udaykapur.com/writing/data-quality-gates-that-actually-work-in-production/https://udaykapur.com/writing/data-quality-gates-that-actually-work-in-production/Most quality gates either fire so often they get ignored or sit silently while bad data flows downstream. Here's how to build gates that catch real problems without crying wolf.Sun, 08 Sep 2024 00:00:00 GMThttps://udaykapur.com/writing/when-your-data-warehouse-needs-a-second-act/https://udaykapur.com/writing/when-your-data-warehouse-needs-a-second-act/Every data warehouse I've joined was already overdue for redesign. The signals are consistent, the migration path is well-known, and the biggest risk is waiting too long to start.Sat, 16 Mar 2024 00:00:00 GMThttps://udaykapur.com/writing/opc-timestamp-utc-gotcha-that-shifts-your-historian-data/https://udaykapur.com/writing/opc-timestamp-utc-gotcha-that-shifts-your-historian-data/When a PLC stores timestamps in local time and the OPC server assumes UTC, every data point in your historian is wrong by your timezone offset. It gets worse during daylight saving transitions.Sat, 28 May 2022 00:00:00 GMThttps://udaykapur.com/writing/maximo-mif-outbound-queue-silent-failures/https://udaykapur.com/writing/maximo-mif-outbound-queue-silent-failures/IBM Maximo's MIF outbound queue can die silently — no error log, no alert, no notification.

It's also silently eating the data points your downstream analytics need to produce correct averages, totals, and trends.Sun, 15 Mar 2020 00:00:00 GMThttps://udaykapur.com/writing/sap-pm-counter-overflow-mining-fleet/https://udaykapur.com/writing/sap-pm-counter-overflow-mining-fleet/When an equipment hour counter resets at its overflow boundary, SAP PM's maintenance scheduling calculates a negative usage delta. The consequences for a mining fleet are worse than you'd think.Sun, 21 Jul 2019 00:00:00 GMThttps://udaykapur.com/writing/ellipse-to-maximo-migration-equipment-hierarchy/https://udaykapur.com/writing/ellipse-to-maximo-migration-equipment-hierarchy/Migrating from Mincom Ellipse to IBM Maximo in a mining operation sounds like a data mapping exercise.
