The Boy in Campus Hallway: From Promissory Notes to Wharton

Introducing Amazon Web Service "Permanent Beta" This is not a sponsored promotion for AWS  Amazon. Matt assessed my setup and was understanding when he learned that the app was hosted on my workstation. He grasped the idea of continuous iteration and failing quickly. He advised me to deploy it on AWS Amazon. Back in 2011, I had no clue what Amazon AWS was, except that they sold books. Thus, with some reluctance, I quietly agreed with Matt, saying "okay Matt," to deploy it on

The Proxywoo Deployment: My 30sqm "Cloud" I completed the build. The app was named Proxywoo . I had architected the features, integrated the GPS logic, and polished the UI. Matt was thrilled; the vision was becoming a reality. He had already settled 75% of the contract, and the 10x return I promised my wife was no longer a "Ponzi scheme"—it was a realized projection. Then, Matt threw me a curveball that would define the next decade of my career: "Deploy the app to the Cloud.

Pivot or Perish By November 2011 two months away from my promise, my brother-in-law pointed me toward a new platform it was called "Online Jobs PH". This was my entry point to the US market. At the time, GPS and Location-Based Services (LBS) were the "New Frontier." Every brand wanted to know where their customers were and wanted to get their business discovered. A client named Matt  posted a requirement for a Location-Based Advertising application. The technology stack: Andr

The First Month The routine was brutal. I woke at 6:00 AM, hit the office by 8:00 AM, and returned at 6:00 PM. To the outside world, I was just another Java developer in the corporate machine. But at night, the 30-square-meter apartment transformed into a Global Command Center.  I set up my freelance profiles and launched a barrage of applications. By morning, the responses would trickle in. I spent my lunch hours conducting high-stakes interviews on the noisy streets of Maka

The Capital Deployment: Building the Engine By 5:00 PM, I was at the doors of an electronics shop, arriving just as the shutters were beginning to close. In business, as in engineering, timing is everything.  I didn't just need a salesperson; I needed all the help available in my mission. I persuaded the technician to stay late. We weren't just "assembling a PC"—we were building the Infrastructure of my Sovereignty. I allocated the $1,000 into a high-spec rig: an Intel i5, 16

The Porch Pivot: A $1,000 Bet on the Mobile Segment It was 3:00 PM on a Sunday in 2011, inside our 30-square-meter apartment. I found my wife on the porch, her eyes filled with a weight that no husband wants to see. She was looking at the tuition for a top-tier school for our daughter—the kind of institution that doesn't just teach, but fundamentally transforms a child’s trajectory. At the time, our daughter was enrolled in a humble urban play school, but my wife was eyeing a

Where is Kubernetes Pod Anti-Affinity Used? Kubernetes Pod Anti-Affinity is a powerful scheduling constraint used to ensure that certain pods do not run on the same node or in the same failure domain (like a rack or availability zone). Its primary purpose is to enhance the high availability and resilience of applications by preventing a single point of failure from taking down all instances of a service. In essence, Pod Anti-Affinity is used in any scenario where the failure

In the simplest terms, a Service Account enables machines such as applications, chatbots, pods, virtual machines, and others to interact with the Core API in Kubernetes. For instance, if you are creating a chatbot that receives commands to set up infrastructure in a Kubernetes Cluster, such as Deployments and Services, Service Accounts are used to grant both authentication and authorization to the chatbot. The diagram illustrates how external applications, like a chatbot, uti

Background Kubernetes allows you to utilize a public key infrastructure (PKI) for client authentication to your cluster. You use a CertificateSigningRequest as part of this process, and either you or some other principal must approve the request. Below is our setup kubectl communicates with kubernetes cluster using csr Step 1: Create a Private Key openssl genrsa -out perry.key 3072 This will generate a private key named perry.ke y openssl private key generation Step 2: Creat

A tip for hiring managers to attract a talented real DevOps applicant during interview.

Why Measure DevOps Success? You cannot have what you cannot measure. It all starts with the balanced scorecard of a company. Perhaps business measurement of success at organizational layer is a faster time to market, better customer experience, and reduced operating expenses. These are some typical key performance indicators (KPIs) in business but how about in DevOps at project level? The sole reason why the DevOps business case has been approved in the first place is to su
