Welcome to springdev — where modern Java engineering and hands‑on learning meet.
We design, build, and teach the technologies that power today’s high‑load, secure, and cloud‑ready applications. Our focus is the Spring ecosystem — the standard for modern Java development used across banking, streaming, and enterprise platforms.
Who We Are
springdev is operated by ECOM ONE LIMITED, a Hong Kong–based company providing digital development services and e‑learning. We combine senior‑level engineering with practical education so teams and individuals can move faster, safer, and with confidence.
Our mission:
Make enterprise‑grade Spring development skills and services accessible to everyone, everywhere.
What We Do
Digital Development Services
We partner with clients to deliver production‑ready software:
- Backend & microservices with Spring Boot/Spring Cloud
- Security & compliance (Spring Security, OAuth2/OIDC, best practices)
- Performance & scalability (profiling, caching, reactive stacks)
- Cloud‑native delivery (Docker, Kubernetes, CI/CD)
- Migrations & modernization (legacy to Spring, version upgrades)
- Consulting & audits (architecture, code reviews, readiness checks)
E‑Learning & Training
We offer practical learning experiences designed for real‑world delivery:
- Self‑paced courses with projects and labs
- Workshops and live sessions for teams
- Certification prep and skill assessments
