Hi! I'm Mike!

I build Cloud Solutions in Rust and Python!

Tackling challenging problems is my passion and I am driven to deliver well-engineered pragmatic solutions daily.

I have worked for over a decade in delivering E2E cloud solutions, with a focus on AWS and other cloud providers.

My experience covers the full stack, where I have spear headed small teams, worked at the corporate level to working with close knit teams, mentored junior devs to being contracted to solve complex issues. This is demonstrated by my time over the past four years at E-Accent BV and RAKwireless. In my former role, my responsibilities included building out networking infrastructure with AWS, tying AWS API Gateway ingress into compute work loads (protected by WAF/Cloudflare) running as load-balanced serverless Lambda functions as well as Rust-based microservices in AWS Fargate (Kubernetes). This included complex network routing such as cross-region cross-account VPC peering etc. as well as maintaining CI/CD pipelines in Gitlab.

Currently my focus is on developing critical backend services in Rust and Python, interfacing with frontends (typically over XHR via RESTful JSON APIs) and other services with gRPC. Such services are benchmarked to ensure optimal performance as production grade workloads.

Rust specific services that I work on are typically implemented with:

  • Tokio (based on Tower): This is an asynchronous runtime, providing an executor for Futures.
  • Axum: Web application framework in Rust.
  • Concurrency: This is a complex topic, and one in which Rust shines; mpsc is just one of many approaches implementing message passing across threads — this allows for data-sharing across threads, and result in [web] services capable of providing high throughput and concurrency, without failing over.

Professionally my advice has been sought by small to mature startups, corporate organisations to large brands such as Autoglym UK, and agencies from different parts of the globe. As a consultant, I am engaged for Application development, Architecture, Design, and Implementation of Cloud infrastructure covering end-to-end Continuous Integration (CI)/Continuous Development (CD) and development lifecycle — having founded CyberdyneAI (by Inertialbox).

My background is that of an engineer in the truest sense — I've achieved a BEng (Hons) 2.ii in Electronic and Computer Engineering from the University of Leeds and a MSc (with Distinction) in Mechatronics from King's College London, United Kingdom. I am also tying my EEE interest with my Cloud/IoT experience with hobby-projects in this particular space with embedded microcontrollers and microprocesses. This work has been supported by the kind folks at RAKwireless by providing free equipment and sensors.

How I work

To give you an idea:

  • 100% Remote only
    • Collaboration using popular tools and platforms - from Github to Gitlab etc.
    • NDAs are easily agreed upon.
    • All code worked on will remain your intellectual property; such details will be in any contract that we agree upon including licensing terms for dependencies etc.
  • Let's have a chat to discuss my hourly rates, which are quite reasonable. Both Short-term work (<20 hours) and contract work (minimum 1-month) are charged at fair market rates. For longer contracts, I am happy to provide a more competitive rate of course.

Screening Calls & Interviews

I am happy to provide letters of reference from my past role, that clearly establish my working experience as a Senior Developer working on web-application development and CloudOps.

Furthermore, I can also provide demo projects that I have built, with attached screencasts (or a live presentation over a video call). If you would like me to solve a _real world_ problem as a pair-programming exercise, that works for me too.

If you absolutely feel the need to give me a test, I prefer a "live" simulation of a real world issue, where details are provided as you normally work to any developer - typically in the form of a "ticket" with as much context and detail around the task at hand.

However, if you decide to ask pointless trivia questions, such as writing a sorting algorithm from scratch, or take a Hackerrank test please do not waste our collective time. I do not accept such requests, period.

Let's work together!

If you're contacting me about a job: please include the phrase "Golf Oscar Oscar Delta, Juliet Oscar Bravo", just so I know that you've done your research. It at least lets me know you reached this page and read this far.

Selected Work

  • When I started out in April 2017 and was handed over Dotpedia — at the time I received a single EC2 instance in AWS with a development stack powered by Rails and Capistrano.

    Dotpedia

    At launch, having taken a 12factor inspired approach, the hand-built stack spanned 8 nodes for production alone. The goal I had been given was to build a system that used AWS but was also "for the most part" Cloud-provider agnostic.

    The front-end is very modern and decoupled from the Rails asset-pipeline; it is Webpack powered (with a light wrapper in Gulp) and AngularJS driven. All credit is due to Walter Dumlao for the frontend wizardry as he is a master with Angular & UI/UX.

August 2019 - July 2021

Rails, ES6/Vanilla JS, React/Webpack, Rustlang (Rust), Python, Advanced bash-scripting, AWS/GCP/DigitalOcean/Upcloud, Advanced DevOps with Ansible & GoCD for CI/CD Pipelines

Responsible for Rails application development and management of Cloud infrastructure consisting of configuration management via Ansible, GoCD CI/CD pipeline and Site Reliability Engineering (SRE).

Cloud infrastructure was upgraded for Ruby & Python dependencies and to Ubuntu LTS 20.04. Each upgrade consisted of creating a separate isolated testing stack, to perform the upgrade and safely make changes as required. Once testing was completed, these updates were then applied to the production stack in co-ordination with the product owner and development team. The same approach was applied for the maintenance of the GoCD CI/CD stack.

Inertialbox

Founder & CTO

June 2012 - present

"Our clients come first and we build their products. Focusing on user experience and simplicity, we write code for mobile and web" — inertialbox.com

WHAT I DO
I specialise in agile development of responsive apps in Rails with a keen focus on business value and user experience. With a mobile-first approach, most clients with a moderate budget (such as startups looking for rapid-prototyping of MVPs) are recommended to take the responsive app approach, expanding to native mobile applications, connecting to the main site via carefully crafted APIs.

Having shipped apps for big, small, and medium-sized companies we also take fault-tolerant cloud deployment seriously and as such leverage DevOps solutions in all our production environments with some of the leading tools and technologies such as Ansible & Docker.

Our mantra is to ship-it-fast with best TDD/BDD practices and CI (Continuous Integration) aiding in minimising bugs and keeping technical debt to a minimum.

RATES & BOOKING
I offer design, architecture, and development services for US$100 - $200/hour for consultancy work. I am open to offering a competitive rate for long-term engagements, those typically lasting beyond 2-months.

Your development time is not confirmed until the minimum has been received and we've both signed my contract, and other contractual matters are arranged (such as NDAs etc). We rely on satisfied clients and repeat projects and therefore always do our utmost in ensuring your expectations are exceeded, every time.

Android (Native) SDK, Retrofit, Eventbus.

The client's organisation approached us with an iOS app for iPad (under Beta) and wanted the same app replicated for Android.

The training tool developed was fairly substantial, with over 60+ views, we tailored these for 600dp/720dp mdpi tablet devices.

Retrofit was used to interface with the client's backend API for authenticated user login; Furthermore, the training tool also contained multiple forms that allow persisting data to the local SQLite DB and allowing users to share the form as a PDF for printing or via email.
