I built a new data ingestion pipeline to ingest high volume of job postings received from multiple sources and partners. I built this using Scala, akka, akka-http, Play Framework, Kafka and Apache Nifi. I also setup a Kubernetes cluster running on AWS which was used for this new ingestion pipeline. I was responsible for introducing all these wonderful technologies to Snagajob.

Other projects I was involved in at Snagajob involved me creating micro services and REST api’s using Python, Flask, Celery.

I worked on the modernization of the Dept of Veteran Affairs eHmp health care system. I was the technical lead of a team of 10 responsible for the development of the platforms sync system. This was a distributed system used to sync patient records across all hospitals. The main stack I used for development was Java, Spring, Dropwizard and Node.js.

Chief Technology Officer, Healthy Choices At Work — 2012-2014

I was a hands on CTO and Engineer at this startup. I architected and developed a custom CRM system for the business. This provided a full end to end solution which allowed customers to sign up for the service and manage their own accounts.

The stack used for this was Python, Django, Postgresql and Elasticsearch. For payments our system integrated with Stripe APIs.

Principal Software Engineer, Incito Networks LLC — 2009-2013

Principal Software Engineer, Powermax Computing Ltd — 1998-2009

If you have worked in the UK as an experienced software developer, you realize that the best jobs from all angles are contract / consultant positions. So during this period whilst living in London UK i worked for many well known companies on the biggest projects as a Principal Software Engineer. In the early years my work solely involved coding using C Programming on a Unix Platform (such as Solaris and AIX) with an Oracle Database backend (included Pro*C and PL/SQL).

In the more later years my coding was mostly done using Java, Spring, Hibernate and Oracle again as the database backend.

The companies I worked for included: O2, IBM, Oracle, National Car Rental.

Education

  • King’s College, University of London — BEng(Hons) in Electronic and Electrical Engineering, Graduated in 1992
  • École Polytechnique Fédérale de Lausanne on Coursera — Functional Programming Principles in Scala

Projects

I contribute to various Scala open source projects. Most notabiliy to Scala ZIO library and group of projects. My main focus and contribution is working on and leading the ZIO-Actors library. A high performance, purely-functional library for building and supervising typed actors backed by ZIO. A Fresh approach to implementing the actor model.

I am also working on and leading ZIO-Zmx a new project that is a work in progress providing monitoring and metrics of ZIO fibers.
