Hi 👋, I'm Sylvère

Backend Developer | Data Analyst, focused on building reliable backend systems and transforming data into actionable business insights.

andrianalisoa-sylvere

I design and build backend systems with a strong focus on architecture, performance, security, and scalability. I enjoy transforming complex business requirements into clean, maintainable, and production-ready solutions.

Alongside backend engineering, I work on data analysis projects using Excel, SQL, and Power BI to extract insights, create dashboards, and support better business decision-making through data.

🚧 Current Projects

Backend systems and data-driven projects focused on reliability, analytics, and business impact.

  • LockCLI — A secure CLI password manager: store, retrieve, and manage your credentials locally from your terminal.
  • MailPulse — Reliable email delivery infrastructure: send, track, and retry transactional emails at scale (WIP).
  • RideSync — Real-time ride dispatch system with microservices, CQRS, WebSockets, Redis Geosearch & RabbitMQ using NestJS (WIP).
  • AuditStream — Real-time financial transaction auditing and monitoring platform (WIP).
