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.
Remote: Yes
Technologies: Systems Architecture, Backend Infrastructure, Ruby on Rails, GraphQL, Node.js / Next.js, Cloud-Native AWS - GCP, AI/ML Pipeline Integrations, Telemetry, CI/CD Automation.
