Shiyam Kumar v

Backend engineer with nearly 3 years of experience building and maintaining Python/PostgreSQL data systems, with deep hands-on expertise in large-scale relational data migration — re-mapping schemas, transforming records, and validating data integrity across major version upgrades (v13 through v17) for customer production databases. Skilled at diagnosing data quality issues, writing complex SQL, and designing reliable, repeatable data transformation pipelines. Comfortable in Linux, Git, and Docker environments.

Transitioning that migration and pipeline-engineering background into a dedicated Data Engineer role.

Software Developer — Upgrade & Migration Engineering at Odoo (2024-03 – Present)

• Build and maintain the core version-upgrade pipeline used to migrate customer production databases across major schema versions (v13→14, v14→15, v15→16, v16→17) — the same data-transformation and schema-evolution problem central to data engineering ETL work.
• Design and validate data transformation logic that remaps tables, columns, and relationships between schema versions while preserving referential integrity and preventing data loss across millions of records.
• Diagnose and fix data integrity bugs surfaced during migrations, in both source and transformed data, restoring correctness and consistency post-upgrade.
• Root-cause customer-reported data issues after migrations, partnering with support and business teams to patch upgrade-path defects — sharpening skills in debugging data pipelines under production constraints.
• Write and optimize PostgreSQL queries and schema designs to support migration performance, data reliability, and downstream application needs.
• Build backend services in Python and REST APIs that expose and move data between internal systems, collaborating cross-functionally to align technical data work with business goals.

Software Developer Intern at Odoo (2023-09 – 2024-03)

• Developed and maintained backend modules using Python, PostgreSQL, XML, and JavaScript, building early proficiency in relational data modeling and query writing.
• Collaborated on data-related solution implementation using Git version control; built foundational SQL and Python skills applied later to migration engineering.
