# I Putu Krisna

Data Engineer with 3+ years architecting scalable Delta Lakehouse platforms across multi-cloud environments.
I am a data engineer specializing in Modern Data Platform and Delta Lakehouse architecture across multi-cloud environments. I design solutions that balance performance, cost, and maintainability, building standardized SDKs, reusable frameworks, and YAML-driven pipelines that enforce governance and improve cross-team consistency. With a product-driven mindset, I translate raw data architecture into measurable business outcomes.

## Work

- [Unified Multi-Client Data Platform](https://dataofme.id/articles/unified-multi-client-data-platform) — Develop end to end AI ready data platform for multi client consumer with modular ingestion library, governed with table driven RAP, RBAC, network policy and SSO integration.
- [Medallion Architecture Data Platform](https://dataofme.id/articles/medallion-architecture-data-platform) — Built end-to-end data infrastructure from scratch using medallion architecture governed on Databricks Unity Catalog, including cost optimization through ingestion restructuring and Spark cluster tuning.
- [Centralized Data Platform SDK](https://dataofme.id/articles/centralized-data-platform-sdk) — Developed a centralized SDK to standardize reusable modules across the data platform with clean-layered architecture and domain driven design, enabling faster development and cross-team consistency.
- [Metadata-driven Data Pipeline Framework](https://dataofme.id/articles/metadata-driven-data-pipeline-framework) — Implemented YAML-driven pipeline modules supporting diverse data sources, near-realtime CDC, incremental batch processing, data contracts, multiple write strategies, and performance optimizations.
- [Data Quality Operations Framework](https://dataofme.id/articles/data-quality-operations-framework) — Created a robust YAML-driven data quality framework with multi-dimensional validation checks supporting Databricks and BigQuery sources, enriched with Slack and email alerting.
- [DynamoDB to PostgreSQL Database Migration](https://dataofme.id/articles/dynamo-db-to-postgre-sql-database-migration) — Initiate database migration project to improve data integrity and solve data quality issue from the legacy data source thus improve analytics accuracy and speed up development process for the long term.
- [Metadata-driven ML DataOps Framework](https://dataofme.id/articles/metadata-driven-ml-data-ops-framework) — Create a machine learning modules that applies agile, DevOps-style principles to the data lifecycle, ensuring that data preprocessing pipelines are automated, reproducible, scalable, and continuously monitored.

## Stories

- [AI Didn't Speed Me Up](https://dataofme.id/articles/ai-didn-t-speed-me-up) — Personal Development: Why I run every project through a structured, multi-stage AI workflow (BMAD) instead of asking AI to just build it, trading speed for staying the one who governs the decisions.
- [Chasing Asphalt Across Bali](https://dataofme.id/articles/chasing-asphalt-across-bali) — Hobbies: A one-day ride across five Bali regencies: Gianyar, Klungkung, Karangasem, Buleleng, and Bangli. Chasing coastline, mountain curves, and a lakeside coffee stop with no fixed itinerary.
- [Golden Hour at First Light](https://dataofme.id/articles/golden-hour-at-first-light) — Life: Skipping Bali's famous west-coast sunset crowds for a quiet 5AM ride to Sanur, where the tide sits glass-flat and the sunrise turns the coast gold before the island wakes up.
