  • MySQL
  • Azure DevOps
  • Terraform
  • Helped drive the adoption of New NewRelic

    We did not have anyone on the engineering team to ensure we could sell New Relic (or the need of an obseravablity tool).

    I stepped up and helped setup monitoring on one of our product stacks outside of my work committments.

    With my endeavours we had a working workload that we could present to show the benefits of NewRelic, which we are now currently using.

  • Revived lunch & learns within the engineering team

    I started lunch and learns again to bring knowledge to the rest of the team.

    I've given three talks so far:"writing integration test with TestContainers", "better obseravablity with NewRelic" and "using event storming for better design"

Stack
  • ASPNet Core
  • AutoFac
  • Nimbus
  • MartenDB
  • Postgres
  • ServiceBus
  • Azure App Service
  • Octopus Deploy
  • Terraform
  • Increased confidence on Ellume Cloud's microservice landscape

    The company lost its tech team as it went through its administration. They needed someone to help the business document the entire distributed system.

    With a strategy and a plan laid out, I was able to document its key workflows and interaction between the microservices. With that report, I was able to provide the team a high confidence for future developers to maintain Ellume Cloud.

  • Develop an EF-esque migration tool for MartenDB

    Ellume Cloud uses MartenDB as its document DB. API requests were triggering schema migrations which caused the application to hang.

    I built a CLI tool (using DBUp and Oakton) that helped succeed in running the migration out of the application's runtime while assuring our blue-green deployment functions.

Tech Lead

FSCO
Stack
  • NestJS
  • Zod
  • Nx Monorepo
  • AWS Lambda
  • Serverless Framework
  • Postgres
  • AWS DynamoDB + S3
  • AWS SQS
  • Terraform
  • Angular
  • Sass
  • Guided team by bringing awareness to a better SDLC

    Revived the e2e project. Aid the team by winning sprint time to complete "happy path" tests, which has enabled the team's confidence in maintaining the front-end and back-end code.

    Introduced structured logging. This improve the time to trace and troubleshoot production issues through Datadog by hours, as previously it was a manual process of sifting and stitching through multiple CloudWatch log groups.

    Created a new release environment that enabled the team to deploy changes (especially the authorization service) without impacting customers while testing internally.

  • Being productive in 3 new tech in a couple months

    It was the highest learning curve for me. I mastered NestJS, AWS stack, and Terraform in two months.

    By then, I was refactoring platform code, improving Terraform and serverless framework configuration for API Gateway, and understanding the nuances of AWS Lambda.

    Improved the CI/CD speed and efficiency by 12% using package caching, parallel jobs and githooks.

  • Increased efficiency of the developer's work by introducing chatbots

    The chatbot was able to recognize flaky services and prompted the team's chatroom.

    Created a CLI that helped scaffold the developer's local environment (in Kong).

  • Increase the teams overall skill in Angular(/JS)

    Mentor and advice across teams through workshops and informal discussions.

    Key contributor in educating Angular, and coaching better code structure (ie: feature module structure), advance toolings (eg: reactive forms), and architecture decisions.

Oct 2008 - Mar 2015

Developer/Technical Consultant

Insight Informatics Pty Ltd
Stack
  • Intersystems
  • BackboneJS
  • JQuery
  • Streamlined the on-boarding training

    New clients were calling in too many times on support issues. I identified what knowledge was lacking; and revised the training material to focus on their needs.

    Improvements were noticed with less support calls and better feedback from client's technical staff.

  • Helped paved the way for mobile presence

    Spearheaded the project to modernize the RPC SOAP API to a minimal REST JSON API, which allowed clients to integrate better. It was a massive undertaking with changes in implementation and documentation on a system that could not have supported it at that time.

    Led and self-managed the deployment of our first mobile App from design to publishing (using Cordova and BackboneJS). First beta version was out in 2 weeks.

2006 - 2008

Programmer

Various internships
  • Improved efficiency by reducing on-site efforts

    Instead of going to a physical digital signage situated around the city to upload news, images, and videos, I came up with a solution to automate content delivery via pull notification.

  • Prototype OMR application accepted by Client on first proposal

    I was able to comprehend Client's requirements and made queries that allow for quick feedback and clarification.

    End result was an application (using VB) that ticked the boxes and, surprisingly, went straight into production usage.
