Records and adjustments
Architecture diagram described in the case study. It is not a product screen.
- Problem
- Track time and breaks without losing clarity around balances, adjustments, and exceptions.
- Decision
- Separate the React interface from the Laravel API and keep calculations and the audit trail on the server.
- Evidence
- The product is live; its repositories and technical decisions can be examined in the case study.
How projects are built
Case studies pair technical choices with the problems they need to solve.
Rules separate from the interface
MuPonto keeps time calculations and auditing in the API. GovIntel AI uses an outbox to coordinate tender indexing without tying uploads to PDF processing.
Data handled with care
Time records need an audit history; in GovIntel AI, every answer must point to verifiable excerpts from the tender.
Decisions that can be examined
Architecture, tests, and implementation challenges are documented on the project pages, with links to available repositories.
Technologies in use
A selection of the technologies documented in the case studies.
APIs and rules
Python, Django, FastAPI, PHP, Laravel, REST, and WebSockets.
Data
PostgreSQL, pgvector, MySQL, SQLAlchemy, and relational modeling.
