Niwi developed and maintained core features for the penpot/penpot repository, focusing on scalable backend and frontend systems that improved reliability, data integrity, and developer experience. Over thirteen months, Niwi delivered robust API enhancements, modernized build and deployment pipelines, and refactored critical data structures using Clojure, ClojureScript, and JavaScript. Their work included implementing transactional HTTP APIs, optimizing WASM interop, and introducing deterministic scheduling with a virtual clock. By upgrading dependencies, strengthening migration governance, and improving error diagnostics, Niwi ensured the platform remained stable and adaptable. The engineering approach emphasized maintainability, performance, and seamless integration across distributed systems and developer workflows.

May 1, 2025May 2025 summary for penpot/penpot focused on modernization, reliability, and business-value delivery. Key features delivered include removal of legacy ZIP format support, schema naming enhancements, and several infrastructure/build improvements that reduce maintenance burden and accelerate release readiness. Major architecture and toolchain upgrades were completed, enabling more robust builds and easier publishing of library components. API and automation capabilities were expanded, alongside safer file handling and state management improvements. Highlights: - Removed legacy ZIP support and migrated export paths to zip.js, simplifying exports and reducing legacy maintenance costs. - Shadow CLJS upgraded across core modules (3.0.3; later 3.1.5), improving build stability and performance. - Refactor of Penpot library and moving it to its own directory to improve modularity and npm publish readiness. - API/infra enhancements: webhook trigger for audit events and addition of get-owned-teams RPC, enabling better integration with external systems. - File handling and state safety: added read-only option for get-file, ensured no persistence on multiple reads, and dereferenced internal state on library file instances. Major bugs fixed included: proper propagation of export errors from workers to the main thread; correct migration ordering for binfile-v1; robustness fixes for HTML paste, shortcuts restore, and various validation/encoding scenarios; and cleanup of persistence-related edge cases. Technologies/skills demonstrated: CLJS/Shadow CLJS tooling, dependency management and upgrades (yarn/npm), API design and OpenAPI-related improvements, CI workflow updates, and testing scaffolding. Impact: Reduced technical debt, more reliable exports and builds, safer file operations, and a clearer path to library publishing and ecosystem integrations, driving faster release cycles and improved developer and user experience.
