Outcomes, not hours
COXSWAIN doesn't sell development hours: it delivers audited, secured and guaranteed products. The fleet accelerates, the engineer answers for it.
Security & SecOps
Hardening, OWASP audits, secrets management, monitoring and incident response. Security isn't an add-on, it's the default.
AI Code Audit & Rescue
Built something with AI and it creaks? We make it production-ready. Fixed price and timeline, concrete report + remediation plan. What we usually find →
Legacy Modernization
Old PHP systems nobody wants to touch, modernized with AI under strict human supervision.
Backend & APIs
Architectures that survive scale and time: APIs, databases, caching, messaging.
DevOps & Cloud
Containerized infrastructure and automated deployment, so the product doesn't go down at 2am.
AI Product Integration
Chatbots, automation and LLM features built right: with evals, guardrails and costs under control.
Ongoing Ownership
We don't vanish after delivery: maintenance, monitoring and a human who answers when something breaks.
Something else?
If your project does not fit any of these boxes, let's talk. The most interesting projects rarely do.
Standard on every delivery
Human review on every line
Dependency scanning

Fig. 02 / Method
One captain, a fleet of agents
COXSWAIN uses AI openly and aggressively: agents write most of the code. The difference: every line passes through an engineer with 10+ years of production scars.
Direction
The engineer sets the architecture, scope and standards. Agents execute within those lines.
Execution
AI agents in parallel: the output of a 4-5 person team, without the coordination overhead.
Verification
Every line read, tested and security-reviewed before delivery.
Accountability
No "the AI got it wrong". Every delivery is signed and stays COXSWAIN's problem.

Case studies
Products operated at real clients, plus the security standard applied publicly, on this very site. No client names: contracts stay confidential, results don't.
Tagger NFC
- Challenge
- Sales teams were losing meeting data: paper notes, CRM filled in at night, forgotten leads.
- Approach
- Mobile app with NFC: one tap saves the contact and context on the spot. On-prem install, data stays with the client.
- Result
- 20+ on-prem installations in daily field use. Data reaches the system in seconds, not at the end of the day.
Auto Workshop Manager
- Challenge
- Auto workshops with history kept in notebooks: missed appointments, customers who never return for service.
- Approach
- Management system with per-vehicle history, appointments and automatic reminders. On-prem: data stays in the workshop.
- Result
- 10+ active workshops. Reminders bring customers back, complete history shortens diagnosis.
Audit & security: this very site
- Challenge
- A site that sells security has to demonstrate it. The standard published above had to be applied publicly, verifiable by anyone.
- Approach
- The standard COXSWAIN audit, applied to our own product: strict Content-Security-Policy, HSTS, security.txt, self-hosted fonts, GDPR-consent form and cookie-free anti-spam protection.
- Result
- Zero external scripts, zero cookies, zero trackers, real security headers. Verifiable in 10 seconds:

FAQ
Do you use AI to write code?
Yes, openly: AI agents write most of the code, and a senior engineer designs the architecture and reviews every line before delivery. You get AI speed without AI risk.
Why not just use ChatGPT to build my app myself?
For a prototype, it genuinely works. For production you need security, scaling, correct data and someone who answers when it goes down. We often repair AI-only builds; sometimes it's cheaper to build it right from the start.
What services does COXSWAIN offer?
AI-accelerated software development, security and SecOps, audit and rescue of AI-generated code, legacy system modernization, backend and APIs, DevOps and Cloud, AI product integration and ongoing maintenance.
Where is COXSWAIN located?
In Bucharest, Romania, working with clients worldwide.
