Senior BI/Data Analytics Consultant, a committed software engineer who seeks to develop elegant solutions to business challenges. My driving force is the passion that pushes me to seek new heights and keep learning the latest ideas, platforms, frameworks, tools, and best practices.

I’m a Technical Lead and Full-Stack Developer with 17+ years of experience delivering robust web applications and SaaS platforms. I have led engineering teams through complex projects, balancing hands-on development with mentoring and process improvements to consistently meet aggressive deadlines. Notably, I helped scale infrastructure and improve performance for SaaS products used by tens of thousands of users. I excel at driving feature delivery end-to-end—whether implementing APIs, optimizing workflows, or guiding teams—as a dependable executor and problem solver.
I do it all, I do iOS (swift and Obj C) , Android (Kotlin and Java), front end (I use my own JS framework, although I know vue or react), and Node Js for my back end, I prefer MongoDB, but I can use SQL like Postgres, Been programming for nearly 20 years so I know the ups and downs.
