Imagine a scenario: You are working at breakneck speed to roll out a new IT product or a business-critical update, but quality control workflows lack efficiency. They are mainly manual and performed late in the development cycle. This challenges your ability to cope with pressing deadlines, innovate, and remain competitive, as manual efforts are slow, workflows lack fast and continuous feedback loops, and critical and major issues arise just before the release.

PostgreSQL is, without a doubt, one of the most popular open source databases in the world. Why? Well, there are many reasons, but if I had to pick just one, I’d say its extensibility. PostgreSQL isnt just a database; its an ecosystem of extensions that can transform it to tackle any upcoming challenges.

The Day Our Serverless Dream Turned into a Nightmare It was 3 PM on a Tuesday. Our "serverless" order processing system built on AWS Lambda and API Gateway was humming along, handling 1,000 transactions/minute. Then, disaster struck. A sudden spike in traffic caused Lambda timeouts, API Gateway threw 5xx errors, and customers started tweeting, Why cant I check out?!

As a CTO, my role extends beyond overseeing technical solutions I work closely with engineering teams to ensure performance testing strategies align with business goals. One of the recurring challenges Ive observed is how sanity testing, despite being a simple step, often determines the success or failure of performance testing efforts. Many teams focus on running large-scale performance tests, ensuring their applications can handle peak loads, but neglect the essential first step validating t
