Staff Engineer / Lead Architect with 15+ years of experience specializing in high-stakes infrastructure, system overhauls, and early product velocity. I partner with tech leaders and founders as an embedded, hands-on technical consultant (15–30h/week) to bridge the gap between initial demos and enterprise-ready systems.
What I specialize in tackling:
- Applied AI & Automation: Integrating AI engines for practical backend workloads, including image classification pipelines, automated log processing, and embedding security scanners into CI/CD workflows to catch and patch vulnerabilities early.
- HealthTech & Diagnostics: Architected platforms integrating complex clinical diagnostic engines, lab systems, and data pipelines with ironclad compliance, deep telemetry, and strict authorization layers.
- Scale & Telemetry: Re-engineered legacy backends, database schemas, and standalone telemetry engines to smoothly process heavy, live data flows and scale to millions of users.
- High-Velocity E-Commerce: Built complex payment gateways, transactional networks, and checkout pipelines designed to handle high-stakes flows cleanly without failure.
- Technical Leadership & Mentoring: Led, unblocked, and upskilled engineering teams to level up implementation paths, accelerate prototyping velocity, and establish sound architectural blueprints.
Looking for direct engagements with founders, VPs of Engineering, or CTOs needing an autonomous technical leader to own core infrastructure paths without executive overhead. Direct client engagements only; no third-party placement agencies.
> Depending on the costs, 600,000 euros a month is pretty good even if it doesn't last forever.
What? 600k euro per MONTH is like you can retire forever in one year. That would be 7mm euro. More than like what most people make during their entire life.
But of course they probably made that in revenue, not profit. Still, I bet they are in a pretty good spot to create a new product, company, etc and with a nice cash reserve if they want to retire.
Btw, according to the article they still keep their old customers, so not like the service has being completely shut down. It's just that they can't take new customers, so at some point they should have pretty low revenue, but maybe they still have a fair amount per month like 100~200k with a super reduced team.
Super relevant! And there are tons of companies looking for Rails developers!
I know some people of the community moved to Rust or Node. But the Rails ecosystem is still the most complete out there.
The framework, as the language, is still evolving, getting quicker and integrating will all sorts of other tools (GraphQL, Elastic, etc).
Ruby is much faster in 2.7/3.x as it was in 1.9/2.0 era.
Rails is starting to try dropping node and all the JS package craziness. But still supports all them. So you can pretty much do HTML-over-the-wire, plain jQuery or go full-blown React/GraphQL/API using webpack or similar.
It's funny how most companies are not really remote because they only hire in the US (even if you can work PST/EST), so they ignore the rest of the World. But I have been using the 'Anywhere' tag and found a bunch on interesting ones.
My company was expecting some money to come this year – like they always do every year – to keep operating. Except this year money kept getting delayed until it never came. They have literally fired all engineers so the company can keep alive and operate until they find ways to get government or other types of money/assistance.
Not like they did this on purpose, but it was related to this epidemy.
Of all services mentioned here, this is the one I like the most and the one I think I'll use.
Their pay as you go makes totally sense when you have a static website that will be access sporadically and you don't want to rely in a public infrastructure such as Github.
I also don't want to depend on freemium services, because they could just shut down the free tier any time.
If it's a personal project and there are no risks involved, it's a change to pick a new, innovative or trendy language, like Go, Elixir, Clojure, Rust, etc.
If it's a personal project, but you want to complete it fast, probably pick whatever you are more comfortable with. Don't try a new environment if you have to deliver in time.
If it's a corporate project and chances you are not alone in that project, pick whatever is more comfortable for the team. Don't try to innovate that much or you have a chance of have a world of not predicted problems with that language/environment.
But if it's a corporate project and you are mostly alone, then you could pick a different language from that world. Some language that you have deeper knowledge that others and maybe you wanted the team to try/adopt. And that's a quite nice opportunity to both showcase you abilities, initiative and the language itself - because companies generally have a hard time adopting new things.
The saddest thing about Twitter's path is that the tool is so good, but if they don't fix the problem you just described (brilliantly btw), they can be doomed.
