Andriamalala Sitraka Rasatarivony

• • Designed the complete architecture of a SaaS product from scratch (NestJS/TypeScript API, PostgreSQL schema, CI/CD pipeline, secure licensing system), making all architectural decisions autonomously.

• • Built and secured high-performance REST APIs (authentication, endpoint protection, secrets management) with a DevSecOps approach applied from the design phase.

• • Integrated AI tools (Claude Code) as a primary productivity lever, compensating for the lack of a team throughout a complete development cycle.

• • Reduced the response time of a critical monitoring application by 25% by refactoring SQL queries and optimizing backend API calls, on a system processing infrastructure data for the entire company's VM fleet.

• • Delivered 10+ full-stack modules into production while maintaining zero major regressions, applying strict TypeScript standards, Docker CI/CD, and systematic code reviews.

• • Participated in team technical decisions (architecture choices, data patterns, code quality) within a multidisciplinary team of 10 people in an Agile environment.

• • Contributed to the development from scratch of an audio-visual e-learning platform for a European client, achieving a satisfaction rate of 75%, within a structured team of 8 people (1 PM, 1 Lead Dev, 1 Designer, 4 Devs, 1 QA).

• • Proposed and implemented UX/UI optimizations based on client feedback, in direct collaboration with the designer and PM, to improve the adoption of the final digital solution.
