- Mobile app development: Android, iOS, PhoneGap/Cordova.
- Cloud hosting: Creating scalable apps that run on Heroku, AWS and Firebase.
- SEO: On-page audits and optimisations including page speed improvements and HTTPS migrations.
- Code quality: Reducing defects in existing projects by introducing test suites, staging + development environments, Continuous Integration, planning boards and code reviews.
Successful examples projects entirely developed and sold by myself:
- Checkbot for Chrome (https://www.checkbot.io/), tests if your website follows 50+ SEO, speed and security web best practices. Rated 4.9/5 with 15K+ active users along with paying customers. The frontend and backend work uses TypeScript, Vue, Firebase, Docker, Node, Webpack, Netlify and Paddle. I'm also responsible for the website, UI design and comprehensive best practices guide that goes with the Chrome extension (https://www.checkbot.io/guide/).
- Fresco for Android (https://play.google.com/store/apps/details?id=org.seanw.fres...), easy to use yet feature packed digital painting app for phones and tablets. The app features layers, customisable brushes, image filters and more. Rated 4/5, over 500K free downloads, over 10K copies sold. Implemented with Java and C.
See https://www.seanw.org for previous projects, client endorsements and more details.
As a Javascript front-end developer, my main experience lies in enterprise scale single page JavaScript applications (SPA’s), preferably built with the Angular 1/2 or React framework. Beside that I have strong business development and leadership skills. Having successfully built my own company from the ground up and run it for 10 years, I know what it takes to build, lead, grow and maintain a business.
Created xtopdf, Python PDF creation toolkit. Freelance developer, consultant and trainer. Worked with startups and large firms, US/IN/NL/CL, products and services.
Skills: Python, C, SQL and database design, Unix & Linux, shell, awk, sed & friends, back end web dev, REST, XML-RPC, XML APIs, PDF generation & text extraction, command-line utility dev (wrote popular IBM dW article on creating utilities, in C on Linux), Flask, MongoDB, SQLAlchemy, software design, testing. Did some Ruby, Rails and Java earlier too.
Was team leader of successful Windows C database middleware product; lots of Unix C work.
Preferred languages are Typescript/Node, Scala, Java, Haskell or other ML-likes (OCaml, SML), or anything unusual, new, or obscure. Experience with automated theorem proving and type theory.
Also a lot of basic web dev experience; that's most of what I've done in the industry. SPAs, Angular, Vue. Linux scripting and ops experience: shell scripts, Docker, Ansible.

Examples of my ideal jobs:
- Working on parsers, compilers, IDE tooling, libraries, API documentation, etc. for new or obscure programming languages
- Developer tools -- new text editors, static analysis for existing languages
- Developing a web application from the ground up (greenfield development, full-stack including choice of languages/platforms and server administration)
- Anything involving functional languages and deep type theory, advanced language features

SEEKING WORK, Big Data Engineer, Primarily Remote (based in Eindhoven, NL)
I am a strong data engineer who is passionate about large-scale distributed systems and streaming pipelines, and cares about producing clean, maintainable, robust Scala / Spark code.
Core Skills:
● Kafka, Spark Streaming, Avro
● Cassandra (Data Modeling, Troubleshooting Performance And Operational Issues)
Other Skills: Airflow, Docker, Kubernetes/GKE, JVM tuning for big data.
Educational Background: Computer Science.
Solid experience working remotely.
All of my recent work history (8 years) is exclusively with startups. I have recently architected and engineered the platform and big data pieces of an end-to-end, turnkey ML platform. References upon request.
SEEKING WORK - London, UK - Remote preferred, happy to visit clients anywhere in the UK.
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.
I'm a full-stack developer with 18 years experience. My specialties are Rails, Postgres and Chef/AWS. I'm also very comfortable in Javascript, Python, and a few other things.
At the low level I've done paid work writing custom Postgres extensions with C and SIMD CPU instructions and implementing performance-critical network services with Rust. At the high level I can design and wireframe features, show their business value, talk to customers, lead other developers, mentor, consult on application architecture, and advise on scaling/performance. You don't want me to pick your color scheme though. :-)
I am reliable, easy to work with, quick to turn things around, and a good communicator. I can work solo or on a team, either as lead or a team member. I value client satisfaction as highly as technical excellence.
