Lead Full-Stack Engineer and Software Architect with 12 years of experience building scalable web
applications, SaaS platforms, distributed systems, and digital products. I have combined strong
software engineering depth with an Industrial Engineering background and experience translating
complex business processes into scalable technical solutions by bridging business operations and
software engineering, converting operational pain points into scalable digital solutions. Strong
hands-on background across Javascript, TypeScript, Node.js, Python, Php, Next.js, Angular, Cloud
Computing and DevOps ( Bash, Docker, Gitlab, IaC, Linux ) and db architecture ( SQL/NoSql ).
I evolved into software development area by building digital SaaS Platform from scratch as
Digitalization of Business Processes in Operational Departments at Siemens AG. I had gained deep
understanding of launching new product from UI/UX Design to Infrastructure Engineering where I
worked with Business Leaders as stakeholders, led dev team of different backgrounds and levels,
resolved blockers in collaboration with other tech and non-tech teams in an inter-disciplined working
atmosphere. I have taken advantage of this inter-disciplined skills on my freelance projects while
handling requierements from different domains and backgrounds. It brought me to have a
comprehensive understanding in both designing and implementing end-to-end systems Particularly
strong in distributed systems, event-driven architecture, API design, frontend architecture, devops
infrastructure, and full-stack system ownership.
