David Hardy
Fullstack Developer



Creating a component library, and make a big enterprise level application landscape? Or want to quickly create prototype PWA? Both are familiar to me using the latest version of Angular, and heavily integrate with my Rx knowledge.


Several successful products I've launched into the work using Firebase. From Auth to Hosing, from Functions to Firetore, I am fluent with all. I've given several international workshops spreading awareness of this amazing serverless product.


Every great application needs a backend, albeit serverless or traditional. With Spring I've created backends designed to scale to any number of users, and expose their goods effortlessly.


The leading mobile operating system of our time is one of my key expertises. In more than 4 years of working experience, I've seen many nooks and crannies of this amazing OS. The quality of the code I produce is of exemplary standard.


For more than 4 years I've been working as a Scrum Development Team member. I've worked with Scrum in small - 1 team - projects, but also in SAFe environments up to 17 team on one project. I've worked as Scrum Master and Product Owner, I am a proud owner of the PSPO I certificate. Also I've been involved in transforming organisation to the agile way of working, with success.


I've been working as a Software Consultant for over 6 years. I am proficient with many programming languages, including (but not limited to); Java, Kotlin, Javascript, Typescript, HTML/CSS, C#, C++, C, Objective C and Swift. I share my knowledge during presentations at several conferences.
