Activities Week 07 (23/03/2026 - 27/03/2026)
Monday (Day 31)
Today, I refined the core architecture of the codebase by implementing a clear separation between the Orchestrator, Service, and Repository layers. This involved introducing the Orchestrator pattern to manage complex workflows, centralizing business logic that previously spanned multiple services. I also introduced type-safe Result DTOs (Result objects) to standardize success and failure responses across the system, significantly improving the error-handling mechanism. In the afternoon, I met with Wesley and Davy to discuss merging the POC changes. We decided to expand the scope of the current pull requests to include the MVP architectural improvements alongside the initial POC features, ensuring a more stable and cohesive codebase for the initial merge into the main branch.
Tuesday (Day 32)
Today, the company held its monthly YappaWaDoeDa meeting during the lunch break, where we discussed company progress and the upcoming month's roadmap. Additionally, Luca, the new marketing intern who started this month, formally introduced himself to the team.
For the rest of the day, I focused on improving code quality and architecture. Examining my recent commits, I accomplished a substantial refactoring of Data Transfer Objects (AiMetadataDto, DigestDataDto, SummaryUpdateDataDto) and standardized exceptions across the platform. I also managed to completely deprecate the legacy PromptTemplateRepository, streamlining database access patterns. This preparation is crucial because Wesley and Davy plan to conduct a high-level review of the codebase to scrutinize service responsibilities and the separation of concerns.
Wednesday (Day 33)
I worked on the delivery infrastructure required for sending content out to users. This involved expanding the DigestOrchestrator and DistributionService to process Symfony entities and route their content appropriately. I introduced a robust structure where specific entities output standardized methods for object interaction, verified by creating comprehensive unit tests like DigestOrchestratorTest.php and PromptTemplateOrchestratorTest.php. The delivery service process now handles each deliverable gracefully.
Thursday (Day 34)
I improved the UI and layout for the knowledge items, AI summaries, and digest reports that are sent via Slack. Furthermore, I worked on embedding these three types of entities directly into the Notion page body. Previously, they were stored merely as database properties without rich formatting. I drove this feature alongside automated verification, writing tests such as NotionSyncContentEmbeddingTest.php to guarantee the embedded content directly injects cleanly into the Notion sync engine.
Friday (Day 35)
Today, I had a stand-up meeting with Davy and Wesley where I presented the current state of the project and confirmed that the MVP is ready for review. I prepared 8 Pull Requests (PRs) that incorporate all previous code review feedback from the POC phase. These PRs are structurally split per domain: the first PR establishes the foundation and base files, while the remaining 7 PRs target specific areas (Knowledge & Category Domain, AI Provider Stack & Summary Generation, Digest Generation Pipeline, Subscription System, Delivery & Distribution Layer, Notion Sync Layer, and Slack Integration Services).
I spent the rest of the day enforcing stability by writing playwright end-to-end (E2E) testing coverage. Based on the git log, I implemented CompleteAiSummaryNotionSyncE2ETest.php and ContentEmbeddingE2ETest.php on the Symfony side, and synchronized the Slack client side with comprehensive suites like digest.test.ts, contentEmbedding.test.ts, and a refactor of dynamicHomeTab.test.ts to ensure the App Home UI interactions map to backend responses.
New skills

Useful data
- Jira Roadmap: [Specific link if available, otherwise just mention tracking]
- GitHub: Updated PR scope encompassing POC and MVP architectural changes
Remarks
This week's focus on architectural refinement has significantly simplified the controller layer and made the business logic much more traceable. The decision to combine POC and MVP changes will result in a more cohesive initial merge into main, reducing technical debt from the outset and providing a solid foundation for upcoming features.
