Verifiable
Family Allowance Certificate Upload and Validation System (Salario Familiar)
Province-wide: used by all school staff in Entre Ríos — teachers, principals, administrative and support staff. Upload, validation and tracking with full auditing and traceability, integrated with SAGE, the province's school management system. It includes a file-upload security layer written from scratch in plain PHP, with no external libraries due to a technical constraint set by the agency.
Cut the average processing time from 4 months to 5 weeks. 20,000 to 30,000 requests per annual cycle and close to 50,000 files. Eliminated paper forms at every school. Presented at an official event in April 2024.
Presenting the system at an official event — Entre Ríos Education Council, April 2024. Press
The agency's official article (in Spanish) credits me as “programador y creador del sistema”.

Case File, Procedure and Internal Memo Management Platform
Covers virtually every case file the Council receives that is tied to payroll processes: thousands of case files, more than 10 departments and around 60 people. It isn't a case-file CRUD — it models the administrative workflow as a state machine, with its own authorization layer separate from SAGE's and managed from a dashboard, plus configurable departments, roles and workflow behavior for whatever changes with day-to-day operations.
Replaced a workflow built on paper and informal knowledge with an explicit flow of states, owners, permissions and traceability.

This portfolio and its chatbot
The chatbot injects the full profile as context, with no RAG: the corpus fits in the context window, so retrieval would be over-engineering at this scale — more moving parts, more latency and a new failure mode in exchange for nothing. The decision is documented in the README. The LLM provider sits behind a swappable interface, with hard rules in the prompt, guardrail evals, rate limiting and a kill switch.
Public, auditable repo. Zero-cost infrastructure.
