I'm a senior developer, specializing in building native Android (Kotlin, Java) and iOS apps (Swift), API back-ends and services (Python, PostgreSQL), and managing successful engineering projects and teams. I was previously the technical co-founder of RateIt, a successful B2B SaaS start-up.

I'm passionate about building great products. I've built popular native apps for iOS and Android (over 20M downloads) and was also a successful independent app developer, where I built a range of best-selling apps and services (https://www.neilwithdata.com/how-i-built-bbsmart).

I'm also the creator of Mastery with SQL - a hands-on practical course for learning modern SQL with PostgreSQL. You can also find my blog at neilwithdata.com
