Software, built by seniors. Amplified by AI. Operated 24/7.
Anyone can generate a demo now. Far fewer can own the judgment behind it — or keep it running in production at 3am. ICE Felix is senior engineers only: we ship your product, then we stay on to run and improve it — automated monitoring around the clock, a senior who actually answers. AI makes us faster; a senior signs off on every line that ships.
Senior-only
Built by people who've shipped to the stores. Founder-led, no junior bench, no hand-offs.
AI as leverage
Senior judgment at AI speed — on our own GPU, not a cloud wrapper. We know where AI helps and where it must never be trusted. No slop.
Always-on
Automated 24/7 monitoring on owned infra. When something breaks, a senior responds — not a ticket queue. We operate your product, we don't abandon it.
Always evolving
A living roadmap: new capabilities and AI features as your product and the tech move forward.
When anyone can generate code, judgment is the scarce resource.
AI made writing code cheap. It made writing the wrong code cheaper still. The bottleneck moved from typing to judgment — what to build, how it behaves under load, where AI can't be trusted. That's exactly what you can't buy from a junior bench or a prompt.
Generation is solved. Judgment isn't.
Generated demos are everywhere; generated production systems become someone's on-call incident. We build for the maintenance window, not the demo.
A senior owns every decision
Every decision is made by someone who has shipped and operated production before. A senior owns the architecture, reviews every line AI helps write, and is accountable for what ships — and what keeps running.
AI in the loop — honestly.
Every agency says "AI" now. So here's the honest version — where it earns its place, where we refuse to trust it, and the owned infrastructure that proves it isn't a cloud wrapper.
Senior speed, AI coverage
Senior engineers amplified by AI tooling — more test coverage, fewer bugs, faster iteration. Not vibe-coding: a senior reviews every line that ships.
Real AI features
AI capabilities inside your product — with an on-prem option on our own GPU (DGX Spark) when your data can't leave the building.
24/7 AI monitoring
AI-assisted monitoring and triage running around the clock on owned infrastructure — issues caught and often fixed before you notice.
We teach this, not just sell it
The founder runs the “Productive with AI” community and trains engineering teams on the same methods we build with. The practice comes before the pitch.
Capabilities.
The full stack, delivered by the same senior people — so the hard, cross-boundary work never falls through the gaps between vendors.
Product engineering
Flutter apps shipped to both stores, web apps, design-to-ship. From MVP to a product you operate.
Backend & cloud
Laravel and NestJS / Node APIs — payments, auth, integrations, real-time. Self-hosted or cloud: your choice, your data.
Data & AI
Production AI on owned GPU — on-prem LLM inference, RAG, ASR (Whisper), and autonomous AI agents (we built UrgentPet's ~1,600-clinic dataset with them). On-prem when data can't leave.
Hardware & embedded
Embedded systems end to end — custom PCB design and manufacturing, firmware, kiosks and totems. We design the electronics and write the software that runs on them.
Quality & delivery
CI/CD, automated testing, headless release to App Store / Play, and PCB fabrication. Shipped means shipped — not “code complete.”
Maintain & evolve
Automated 24/7 monitoring on owned infra, support with a defined response target, and a monthly innovation budget — the Care model.
Domains we've shipped in.
Domains where we've already shipped a real, verifiable product — not a wishlist of logos.
Consumer apps & marketplaces
Two-sided products, real-time dispatch, billing, push — built to hold up under real traffic.
HoReCa & loyalty
Retention products: signed-QR loyalty, analytics, push campaigns, self-hosted.
Automotive & events
Interactive kiosks & totems that run unattended on a live show floor.
Education & e-learning
Learning platforms and engineering education — co-founded and built.
Developer tooling
Native-API Flutter packages, published and maintained for the community.
Fintech & new domains
Senior judgment transfers — fintech and beyond. Bring us a domain we haven't shipped in yet; it can be next.
Build. Operate. Evolve.
Most studios ship and disappear. We stay — one senior partner across the entire life of your product. Most clients begin with a single build, then keep us on to operate and grow it. Care is how the relationship continues, not how it begins.
Build
- Discovery → hi-fi design you approve
- Senior, AI-amplified delivery
- Mobile · backend · hardware · AI
- Store submission / fab — we finish
Operate
- Automated 24/7 monitoring on owned infra
- Response target: same business day — a senior who knows your system, not a ticket queue
- Proactive fixes, security & dependency upkeep
- Crash-free & uptime watched, not assumed
Evolve
- A monthly innovation budget
- New features & AI capabilities
- Performance & UX improvements
- Your product gets better while it runs
Three ways to work with us.
Pick the commitment that fits where you are — and move up only once we've shipped together.
Build Sprint
One product, fixed scope, fixed price. Senior, AI-amplified delivery — shipped to the stores or fab. The de-risked first engagement.
Senior augmentation
Bring senior capacity onto your team — the founder plus a vetted bench of senior collaborators, in your stack and process. Mobile, backend or AI capacity without a hiring cycle.
ICE Felix Care
We operate and evolve what we built — automated 24/7 monitoring, a response target, and a monthly innovation budget. The natural next step once we've shipped together.
Proof — products we built and run.
Real, verifiable work — apps in the stores, hardware on event floors, AI on our own GPU. Click any one for the full story.
You talk to the person who builds it — and who teaches the AI methods we build with.
ICE Felix Care — we operate what we build.
Once we've built it together, we keep it alive and make it better. Three ways to keep us on. Founder-led capacity is limited — we take a few at a time.
We keep it alive.
- 24/7 monitoring on our owned GPU
- Crash, uptime & security alerting
- Dependency & patch upkeep
- Response target: next business day
- Monthly health report
We run it like it's ours.
- Everything in Watch, plus —
- Priority response target: same business day
- Proactive fixes shipped, not just flagged
- Release & store management
- Small change requests included
- Monthly working call
It gets better every month.
- Everything in Operate, plus —
- A monthly innovation budget (senior-days)
- New features & real AI capabilities
- Performance & UX work
- Quarterly strategy session
Talks & open source.
We'd rather show the work than mill content — real talks, a community we run, and code anyone can inspect.
icefelix.com on pub.dev
Verified publisher of native-API Flutter packages for Android, iOS and Linux — public, inspectable proof.
Productive with AI
The meetup the founder runs on getting real engineering leverage from AI — the same methods we build with.
Conference & meetup talks
Dozens of talks — DevTalks, Codecamp, FlutterCon Berlin, WordCamp Europe — on shipping real products.
Start with one build —
keep us as long as it's earning.
Senior-built, operated 24/7. Founder-led, no sales funnel — usually a reply within a day. We take a few projects at a time, so a 2-line brief helps us say yes fast.
