What I'm looking for

I seek senior integration or middleware roles that involve end-to-end API and cloud migration work, collaborative DevOps environments, clear documentation practices, and opportunities to improve reliability and performance in enterprise banking systems.

I am a middleware engineer with 10+ years of hands-on experience designing, developing, migrating and supporting enterprise integration solutions using IBM IIB, IBM MQ, Datapower and transformation tools. I have led integration and cloud migration efforts for banking clients across Latin America and supported full lifecycle environments (DEV, IST, QA, UAT, PRD), emphasizing robust testing, documentation and bug resolution.

I hold multiple IBM certifications (IIB v9/v10, Datapower) and a background in automation engineering, with strong skills in API testing, database access, DevOps source control and message transformation (WTX, Mapforce). I communicate effectively with technical and non-technical stakeholders and deliver reliable, well-documented services aligned to business architecture.
