I have worked at Plus Technology Solutions since 2022. These are the kinds of problems I solved there; the product and its clients are confidential.
Client projects under NDA: a mobile app and website on top of Odoo, SOAP-to-REST integrations, and push, biometrics and NFC on mobile.
A regulated B2B SaaS platform in production, from the backend to the mobile app. Since 2024 I have been its main developer, reporting to the general manager.
Design of the next platform, plus Odoo, WhatsApp and AI projects for clients.
I moved a system with years in production from Spring Boot 1.5 and Java 8 to Spring Boot 3 and Java 21, and its frontend from Angular 10 to 17, adding Docker and Redis on the way. For the next major version I migrated it to WebFlux and led the frontend rewrite in Angular 21.
MFA, device-bound sessions, sign-in approval from the mobile app, SSO with OIDC and SAML, and rate limiting. I also fixed access-control and XSS flaws.
PDF and Excel generation at scale, resumable bulk jobs spread across a two-node cluster, and usage-based billing with refunds. I measure in production before I optimize.
I proposed and started building a reactive microservices platform: one database per service, messaging with dead-letter queues, API contracts that generate the TypeScript client, and distributed traces that follow a request through the queues.
I connected ads that open WhatsApp to an Odoo CRM, with a first-contact bot that hands the conversation to a person and an AI agent that books appointments only in free slots.
