Sr. Microservices Developer / Electronics Engineer

I have multiple years of senior developer and architect experience, with the last 6 years on full-stack cloud microservices architecture with Docker / Kubernetes. I bring a solid mix of non-freelancing and freelancing experience working with multi-national teams from across the globe on both private and government sectors. A highlight during my pre-freelancing days was leading a team that migrated a universal bank's 17-year-old Trade Finance System (a.k.a. SWIFT "MT700 - MTxxx" series) from COBOL + Oracle to Groovy Grails + IBM DB2. I am also a Board-certified Electronics and Communications Engineer in the Philippines (PRC ECE License # xx876), and aside from software, I also have interests in hardware (gaming / server rigs, overclocking), electronics (IoT / embedded), and solar power. I am constantly learning to innovate. Some of my core domains: - Banking - Fintech / financial services - E-commerce - ERP / CRM - Blockchains / cryptocurrencies - Telecoms software engineering (GSM Parlay X / OneAPI) I have worked on projects for Accenture, Huawei Technologies, Deutsche Bank, Morgan Stanley Asia-Pacific (Hong Kong), Banco de Oro Universal Bank, UCPB Universal Bank, PDex (Philippine Dealing & Exchange Corp.), and Bureau of Treasury of the Philippines and GSIS (gov't. financial agencies), among others.
