Secure backend systems
Java and Spring Boot services built for scale, with Spring Security, clear API contracts and production-minded data models on PostgreSQL.
Software Engineer
Yves Thibaut Tsague
Backend systems, architecture & production reliability
Expertise
What I build: secure backends, payment-grade platforms, and operable cloud-native systems.
Payments & platforms
Unified payment flows, mobile money integrations and fintech-grade APIs where reliability and auditability matter.
Cloud-native & DevOps
Containerized workloads, CI/CD, observability with Grafana, Loki and OpenTelemetry, and infrastructure that stays operable.
Selected projects
Production systems across associations, payments, institutions, education and infrastructure.
ASSO+
Lead Full-Stack Developer
Associations, community groups and tontines often manage contributions, meetings, sanctions, savings and member records manually. I designed and developed a centralized platform that allows organizations to securely manage their financial and administrative activities from a mobile application and an administration dashboard.
Stack — Java, Spring Boot, Spring Security, PostgreSQL, Kafka, Redis, Docker, Flutter, Next.js, GitHub Actions, Grafana, Loki, OpenTelemetry
FarotyPay
Backend Developer & Software Architect
Businesses often need to integrate several payment providers separately, which increases complexity and maintenance costs. I contributed to the development of a secure payment gateway that centralizes payment processing through a unified API and supports integrations with mobile money and other payment services.
Stack — Java, Spring Boot, REST APIs, Spring Security, PostgreSQL, Docker, Nginx, GitHub Actions, Grafana, Loki, AWS S3
MoMo Ticket
Lead Backend Developer
Designed and developed the backend of MoMo Ticket, a modern event ticketing platform for MTN Cameroon, using a microservices architecture. Built secure APIs for event management, online ticket sales, attendee management, organizer dashboards and payment integration, delivering a scalable platform capable of supporting high-volume events.
Stack — Java, Spring Boot, Spring Security, PostgreSQL, Microservices, Docker, Next.js, REST APIs, MTN MoMo, Visa, Nginx, Cloudflare
CIDP International Platform
Full-Stack Developer & Infrastructure Engineer
The Conseil International de Dialogue et de Partenariat needed a modern platform to present its activities, publish content, receive donations and manage its internal information. I developed the public website and a complete administration dashboard for managing blog posts, donations, team members and article visit statistics. I also configured a private email server so the organization can create and manage professional email accounts under its domain.
Stack — Java, Spring Boot, Next.js, PostgreSQL, REST APIs, Docker, Nginx, Linux, Mailcow, Cloudflare
Cloud Infrastructure & CI/CD
DevOps & Backend Engineer
Manual deployments and limited production visibility made application maintenance slower and riskier. I implemented a containerized deployment workflow with automated builds, versioned Docker images, centralized logs, monitoring, alerts and backup preparation.
Stack — Docker, Docker Compose, GitHub Actions, Docker Hub, Linux, Nginx, Cloudflare, Grafana, Loki, Prometheus, OpenTelemetry, AWS S3

Journey
Software Engineer with over 5 years of experience designing and developing secure, scalable backend systems using Java, Spring Boot, PostgreSQL and Docker. Experienced in cloud-native applications, payment platforms, REST APIs and microservices. Passionate about software architecture, DevOps practices and delivering reliable production systems.
5+ years
Software engineering in production
Designing and shipping secure, scalable backends — from payment platforms to community and institutional products.
Focus
Architecture & reliability
Microservices, REST APIs, observability and DevOps practices that keep systems operable after launch.
Today
Building what lasts
Still drawn to hard problems: payments, multi-tenant platforms, and cloud-native delivery with clear ownership.
