Ask HN: Freelancer? Seeking freelancer? (November 2018)

Location: North-east UK

What I do: Prototype development. Feasibility studies. Data migration, transformation, and processing.

In the past I've been a network engineer, run large-scale Debian installations doing devops before it had a name, and been responsible for servers in Antarctica. I have experience with a wide range of different Unix tools and technologies, at various levels of the stack. This gives me the ability—and the perspective—to pick the best combination of tools for any particular project, rather than simply treating everything as a nail because all I have is a hammer.

I focus particularly on taking on “weird” or niche data or exploratory projects end-to-end; things that wouldn’t be a fit for a standard web or development agency.

Previous work:

* Custom domain specific language (DSL) to encode business rules for computer vision system (Common Lisp)

* University library data migration project, with a focus on completeness and validation. (Clojure, Elixir, Ruby)

* School data processing app (Elixir/Phoenix, PostgreSQL)

* Custom data dashboards (R, Geckoboard)

* High-reliability, long-term timelapse platform for inaccessible locations. (FreeBSD, Arduino, Python, Shell)

* Migration of existing Node.js+Firebase service to Golang+PostgreSQL on AWS

* Feasibility study investigating the possiblility of writing custom code to interface with a biometric timeclock (Common Lisp)

* Proof-of-concept hardware development for projects linking the physical and virtual worlds in real time (Arduino, Node.js)

Buzzwords: Debian, Ubuntu, AWS, PostgreSQL, Perl, Common Lisp, Clojure, Ruby, Go, Arduino / AVR, Elixir / Phoenix, FreeBSD

Willing to relocate: For periods of time, yes.

Technologies: JavaScript, Node, React, React Native, AWS, Azure.

I am a full-stack developer who have been part of a few startups, created my own way back, and am currently building a large web application for a client, due soon.

DevOps / Python guy with a decade's experience building, hosting and tuning applications.

I work with engineering teams to make their products as scalable and robust as possible. AWS, Kubernetes, load testing, 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.
