Marica D'souza is a Berlin-based senior software engineer with eight years of experience building full-stack systems, currently at eBay Deutschland after leading engineering work at Frappe and ALYF. A practical generalist and open-source maintainer, she has reviewed hundreds of PRs and shipped large refactors for ERPNext and Frappe Framework, improving e‑commerce, manufacturing, and scaling core algorithms to handle 400K BOMs. Her work spans Python, JavaScript/TypeScript and React, and includes backend-heavy contributions to open-source ERP and compliance projects—fixing payroll, tax, and invoice logic in widely used repos. She builds pragmatic integrations and high-performance APIs (including a bank reconciliation tool, million-dollar e‑commerce pipelines, and sub-0.1s cached response regeneration) while obsessing over clear UX and the deepest “why” behind problems. Colleagues know her for excellent PR descriptions and a habit of keeping most of her work public on GitHub, with more private projects slated to be released soon.
