Summary
👤
Senior🎓
Top SchoolRaymond Mar is an independent contractor and data-focused analyst with nine years of hands-on experience turning messy datasets into actionable insights using Python, R, Power BI, SQL, Power Pivot/Query, and ETL workflows. With a background in economics and accounting, he combines rigorous data validation and reporting skills from roles at Cisco and Palo Alto Networks with practical product and e-commerce improvements that boosted site traffic and sales. A late career bloomer who deliberately self-trains, he rebuilt his technical toolkit—writing a Twitter API, maintaining analytics projects, and practicing data modeling—to bridge support, analytics, and engineering teams. Known for a persistent work ethic and curiosity, he thrives in support roles that prioritize stakeholders’ comfort while quietly expanding into web and scripting skills like HTML, CSS, and JavaScript. Based in San Jose, he pairs analytical discipline with varied interests—from distance running to board games—which informs a steady, research-oriented approach to problems.
