Recently I’ve worked on a project where we enabled Redis caching for our web applications. So for that, I had a chance to develop a custom reactive spring-boot Redis cluster client library (for a Spring webflux project) and integrate it. The problem I faced was the AWS Redis cluster nodes were not available for my office VPN (maybe ssh-ing to the bastion server and trying to connect Redis will work, I haven’t tried it).

Few months after joining my first company, I had a chance to work in a new service. In this service, they have planned to use reactive programming paradigms as the service is needed to handle events asynchronously. So, I had a great opportunity to learn this new reactive programming paradigm and share my knowledge with my team members😄. For this new service, they’ve planned to use a Spring-boot Webflux stack with project reactor support.

It’s been a while I wrote a new post about tech. Recently I started to work on this application which needed to upload contents to an Amazon Web Service S3 storage using a pre-signed URL. Uploading to a S3 is bit trick with this pre-signed URL because AWS documentation is a bit messed up for me. So after completing the task, I wanted to blog a complete tutorial on Server-Client application for AWS S3 Pre-signed URL using Nodejs SDK.

1 IntroSince my AL days, I wanted to build a Nixie display clock. As parts were so pricey and less knowledge about electronics I didn’t start it. So yesterday I stumbled upon a Nixie display clock while watching some youtube video. Since that, all I wanted is to build one. If you are interested in how a nixie tube is made, watch this video. This will be a long project as I’m going to build this in my free time.

1 IntroSince the day my friend Kasun Vithanage (AKA Saaluwa) introduced this Hugo framework, I wanted to build my web site using this framework. But due to other things I didn’t have time for that. After some lazy days/months, I just had this instant urge to try this framework. So, here we are. On my site writing this blog post :D. 2 My Blogging LifeI started blogging after my OL examination, back in 2009.
