A little about me

I’m a multi-disciplined Software, Reliability, and Cloud Systems Engineer with over two decades of experience spanning various client, server and cloud infrastructure technologies. I've worked with and been a part of multiple startup founding teams and have worked at large market-leading Fortune 500 technology companies.

I've authored technology courses, collaborated on books (co-author, technical reviewer, etc), and provided corporate trainings to large technology companies. These days I work extensively with Go (golang), AWS (ECS, Fargate, Lambda, CloudFormation, etc), Microservice Architectures, and Serverless Architectures. I professionally teach the technologies I use on platforms like LinkedIn Learning, O'Reilly, Packt, and others. Whenever possible, I also teach programming workshops at no cost to learners in my local community.

Some of the highlights of my professional career so far include:

  • Architecting a cloud platform for skill inventory, skill gap analysis, and professional development for Information Professionals and Libraries with Skilltype
  • Establishing Site Reliability Engineering practices and tooling at Salesforce's Heroku
  • Building microservice and serverless applications and tools that leverage the AWS cloud to further the mission of The Achievement Network
  • Bringing Enterprise-grade time series database and cluster management solutions to market at InfluxData
  • Leading the development of the backend infrastructure for the popular consumer IoT device, Pavlok, complete with integration of services like IFTTT
  • Architecting visual merchandising technology at One Door
  • Educating the next generation of software developers at Launch Academy
  • Building the Boston-based digital agency, MAARK

My love for technology is matched only by my passion for community service:

Education & Certifications include:

  • Master of Science in Cloud Computing Architecture
  • Bachelor of Science in Computer & Information Science
  • AWS Certified Solutions Architect
  • AWS Certified Developer
  • AWS Certified Cloud Practitioner
