Alex Arno headshot

I'm Alex.

I build solutions, not features.

Spent 6 years working on systems that can't fail.

Now I build software that never will.

Current Mission

A decade in aerospace taught me to catch problems before they become disasters. Now I build products that automate the boring stuff, so that you don't have to.

The Factory Floor

19 organisations, 340+ repositories, 36 domains -- one vision

Every great factory starts with a blueprint. This one started with a question: what if you could build an entire software empire from a single desk? 19 GitHub organisations, each with its own purpose, architecture, and identity. Connected by shared infrastructure, unified documentation, and a relentless obsession with modularity.

How I Work

Core principles that guide my projects

SRS-TLS-001
Purpose
Profit
I don't start with MRR in mind.
I build things that solve real problems I've encountered. If it's useful, the business model follows naturally. I love creating value I'm proud of, regardless of immediate returns.
SRS-TLS-002
Systems
Symptoms
Each problem has many solutions.
Where others see blockers, I see design constraints. My degree taught me that elegant solutions come from understanding the whole system, not just patching the broken parts.
SRS-TLS-003
Right
Rushed
Build it right the first time.
I'd rather spend an extra day building it right than a week fixing it later. The #buildinpublic community keeps me accountable by watching the process, not just the outcome.
SRS-TLS-004
Learn
Launch
Every failure teaches something valuable.
I share mistakes as openly as wins because that's where the real insights live. Each project teaches me something new about users, systems, or myself.

My Journey

Critical milestones in the journey from aerospace to digital products

PHASE 01
2014 - 2018

The Foundation

MEng Aeronautics & Astronautics with Spacecraft Engineering from Southampton. One dissertation on hybrid electric propulsion. One Masters thesis on gridded ion thruster neutralisation using ECR plasma -- a Design Excellence Award contender.
Key Systems
MEng Southampton, ion thruster thesis, hybrid propulsion dissertation
Thesis focused on stationkeeping of GEO telecoms satellites. Primary modules in Spacecraft Systems, Propulsion & Structures, Avionics, and Advanced Computational Methods. Earlier IB extended essay: "How Changes in Aircraft Wingspan Influence Range."
MATLABCOMSOLANSYSXFLR5SolidWorks
PHASE 02
2016 - 2017

The Satellite Years

Two internships at SES Astra in Luxembourg -- Flight Dynamics and Power Subsystem engineering. Built real-time telemetry tools for the O3b constellation at MEO, serving connectivity to the "other three billion."
Key Systems
O3b MEO constellation, real-time telemetry, thermal modelling
Flight Dynamics: designed a verification tool synchronising O3b and SP3 satellite visibility across internal systems. Power Subsystem: engineered a tool correlating an empirical thermal model of operational temperature, EPC power, and solar inclination angle with real-time telemetry. First exposure to systems where you cannot ship a patch.
MATLABTelemetry SystemsOrbital Mechanics
PHASE 03
2018 - 2024

The Aviation Years

Avionics systems engineering on the Boeing 777X Common Core System and the Xi'An MA700 turboprop. Network protocol verification, propeller control systems, and every metrics dashboard you can imagine. Real systems where failure isn't an option.
Key Systems
Boeing 777X RDC, MA700 PEC, network analysis, metrics dashboards
777X: defined Input Requirement Files for unit testing network protocols in the Remote Data Concentrator (RDC). Led development of a Problem Report & Change Request metrics dashboard for Boeing. Returned as consultant to build a custom packet capture utility for RDC network traffic and a Test Procedure Suite to reduce technical debt. MA700: built a MATLAB AppDesigner GUI to verify the PEC Simulink model -- real-time observation of propeller speed and pitch across flight phases for the Pratt & Whitney PW150C. Led an intern team managing the systems lifecycle of a Micro Interface Unit.

PHASE 04
2021 - 2023

The Transition

Started freelancing while still doing aerospace work. Contributed to Brandwatch (processing billions of social conversations) and Nocodelytics (Webflow's recommended analytics, used by Slack and Jasper AI). Realised I love building digital products as much as physical systems.
Key Systems
Brandwatch, Nocodelytics, full-stack migration
Brandwatch: full-stack migration and testing -- converting massive dynamic blog and report templates from PHP to TypeScript, ensuring thorough typing and test coverage. Nocodelytics: frontend consulting, shaping the analytics interface for the Webflow Marketplace recommended tool. Where aerospace-level rigour met startup-speed shipping.

PHASE 05
2023 - present

The Maker Era

Discovered #buildinpublic and everything changed. The community gave me validation, feedback, and accountability I never had building in isolation. Now I build things because they need to exist, sharing the journey every step of the way.
Key Systems
Skyflow, Password Please!, PunPal, devarno.cloud
Founded DevArno. Built Skyflow (Bluesky analytics with AT Protocol + FastAPI), Password Please! (open-source generator with 6 methods), PunPal (24-hour MVP). Now building the devarno.cloud ecosystem -- 20+ services from a Go backend to a family hub. Still not entirely sure how I got here.

Random facts that define my days

Always Looking Up

Flight

Forever captivated by the skies and stars, that same curiosity now draws me toward the cockpit of a Piper or Cessna. Guided by Dr. Angelo Grubisic, whose infectious passion for aerospace and fearless pursuit of flight left a lasting mark on everyone he taught. Angelo had a rare gift of making the impossible feel achievable - which to this day still makes engineering feel like my greatest adventure.

Amphibious Aspirations

Swimming

A university taster session sparked my competitive swimming journey. I spent my degree swimming rigorously and serving two years on the committee. A decade later, I’m a competitive Masters swimmer that broke the 25-second barrier by just one hundredth of a second, and still chasing sub-24 glory.

Progressive Polyglot

Languages

Fluent in four languages, with Norwegian and Greek on the side. Continuously expanding my skills, Dutch, German, and Portuguese are on the wishlist, while discovering the nuances, idioms, and humor that each culture brings.

Home Fermentation

BUBBLES

Crafting traditional and experimental fermented goods. Passionate about kefir, kimchi, and mead, while also experimenting with kombucha and vinegar. Always exploring new flavors, techniques, and the science behind living cultures.

Beats and Bites

Scripting

Lifelong guitarist and part-time chef. Grew up on Queen, The Beatles, and Simon & Garfunkel. Played in three rock bands and the school jazz orchestra. Spent two years DJing at University, and now find comfort in jazz of all kinds, fueling coding sessions with eclectic playlists (and many kiwis).

Masters in Motion

Momentum

Fascinated by peak performance and mastery. I dissect MasterChef techniques and Olympic strategies for fun, and I've backed Jannik Sinner since day one. Uncovering the routines, focus, and mindset that turn talent into true craft is what makes this journey exciting.
