SEEKING WORK - Contract, Remote, based in NYC area, backend engineer

I am a backend expert, having built and maintained highly available systems for several companies over the last 5 years, in addition to over 20 total years of software development experience.

The ideal engagement at this point would be with a firm that expects to need team-level help and wants to try me out as the lead for that on a smaller initial project.

You will like working with me because I:

* hold your goals as my priorities

* communicate verbosely yet synthesize well

* my rates are reasonable in exchange for the value I deliver

* I guarantee I will get the job done

Concrete examples:

* built realtime stats and the enterprise-wide developer portal for one of the top 3 major US sports leagues (golang/pyspark/docker/azure)

* portfolio management process replatforming for a midsize hedge fund (bespoke->dockerized python aws lambda architecture)

* built a ~50 node, Dockerized, Terraform-deployed distributed system to provide realtime, transformed trade data from crypto exchanges to a Kafka pipeline and data lake (fodder for an analytics platform). Met 5000msec SLA across arbitrarily many exchanges and ticker symbols. Blue-green deployment for complete CICD safety. Cloudwatch metrics proved SLA was met and provided general system oversight.

* built a framework to collapse dozens of singleton ETL programs into one config-driven, simple C# application performing the same functionality at ~80% reduction in maintenance cost year over year.

* built and managed a team of 8 engineers operating against multiple streams of work to meet business needs, with ~12 active projects at a time.

SEEKING WORK - Remote (London based), happy to visit you anywhere in the UK.

DevOps/Python consultant with a 15+ years experience building, hosting and fixing applications.

I work with engineering teams to make their products as scalable and robust as possible. AWS, Kubernetes, load testing, lambdas, CI, deploy systems, monitoring, config management, security audits, dev projects of my own - you name it I've done it.

Recent projects include:

+ Re-hosting a large microservice node.js + RethinkDB web application on Google Cloud. The resulting stack (serving a busy news site) is deployed to GKE with a set of Helm charts and a minimal amount of custom tooling for CDN & image serving. GKE has turned out to be low-maintenance and rock solid; I'll be glad to work with it again.

+ Rewriting a Python big data stack for a bioscience client. Result was a robust, scalable system deployed with Terraform/Docker to spot instances managed by AWS Batch. Benefits included better resilience, higher resource utilisation and vastly reduced cost/processing time.

+ AWS/Kubernetes/Docker deployment to support a large distributed (15 microservices + persistence layer) application. Updated a sprawling Django/Postgres app to fit modern containerised hosting, resulting in a stack that makes great use of k8s' scaling & resiliency features. Templating via Helm for multiple, namespaced stack instances & continuous integration.

+ Another AWS/k8s/Docker stack, this time with a persistence layer comprising Cassandra & Kafka with service discovery through Zookeeper. Prometheus & Grafana for monitoring.

+ Large multithreaded Python 3 application for automated crypto trading. Didn't get rich, still posting on here.
