What does ARCHDEVS do?
ARCHDEVS is a software studio in Pitești, Romania, founded in 2025 by Marius Mircioaga. It does two things: white-label full-stack and AI development for agencies that have more projects than developers, and audits, upgrades and maintenance for legacy or AI-built applications. Its founder has shipped 12+ products for clients in Romania, Italy and the United States, before and since founding the studio.
How does white-label development work?
The agency sells and manages the project; ARCHDEVS builds it. Code, deployments and documentation ship under the agency's brand, and the end client never has to know a subcontractor was involved. It suits agencies with overflow work, a missing skill such as AI integration, .NET or mobile, or a deadline the in-house team cannot meet.
What does the 5-day audit include?
A written audit delivered in 5 days, covering performance, security, dependency and end-of-life status, and architecture risks, using tools such as Lighthouse, WebPageTest, k6, Sentry, Snyk and OWASP ZAP. It ends with a costed upgrade path. From there you can order a fixed-scope upgrade and, optionally, a monthly maintenance retainer.
What is the difference between the free 5-minute performance check and the 5-day audit?
The free 5-minute check is for websites: send the URL and you get an email reply with what is slowing it down and what to fix first. The 5-day audit is a paid, written report on an application: performance, security, dependency and end-of-life status, and architecture risks, with a costed upgrade path.
Can you take over an app that was built with AI coding tools?
Yes. Apps generated with AI tools often work in a demo but need hardening before real users arrive: authentication, error handling, the data model, tests, hosting and monitoring. The audit lists exactly what needs fixing and what it costs, the upgrade fixes it, and the retainer keeps it stable.
Which technologies do you work with?
TypeScript, React and Next.js on the front end; Node.js/Express, Python (FastAPI and Django), C#/.NET and PHP/Laravel on the back end; PostgreSQL, MySQL, Elasticsearch and Supabase for data; React Native and Expo for mobile; Stripe and PayPal for payments; Docker, Nginx and Heroku for deployment; and the OpenAI Agents SDK with RAG over vector stores for AI features. The largest published case study, Majordom, runs on .NET 8, FastAPI and Next.js 15 with 86 API endpoints.
Where are you based, and do you work with clients abroad?
ARCHDEVS is based in Pitești, Romania (Eastern European Time, UTC+2/+3) and works remotely with clients across Europe and the United States. Projects to date have been for clients in Romania, Italy and the US.
How do I start?
Email contact@archdevs.org or call +40 770 770 365. For an audit, send the app's URL or repository access and you will get a quote for the 5-day audit. For white-label work, send a short brief and the agency's timeline.
