Start with a technical discovery
Bring us your business problem. Our architects will help define the scope, tech stack, and roadmap.
Schedule a consultationTechnical Expertise
We build reliable systems, not isolated components.
Our engineering team translates complex business requirements into secure, maintainable software architectures.
Mobile Engineering
Native and cross-platform mobile experiences optimized for user retention and smooth performance.
System Integration & APIs
Connecting fragmented enterprise systems to automate data flow and eliminate manual business operations.
Intelligent Workflows (AI)
Integrating practical artificial intelligence to automate repetitive data processing and decision-making.
Total Cost of Ownership
AI accelerates code. We guarantee the product.
Generating code is fast. Ensuring that code meets security standards, handles edge cases, and scales reliably is where true engineering value is created.
Zalo Mini App Development
Built for customers and business teams.
We build customer-facing experiences and business tools that work together across the web, mobile, and Zalo Mini Apps.
Customer experience
Seamless service booking, directly inside Zalo.
A complete customer booking journey built for Zalo — from discovering services and promotions to selecting appointments and completing verification.
Business operations

Give business teams access to the information and workflows they need on the move — including staff, inventory, revenue, reporting, and store operations.
The PRX Advantage
Serious software engineering. Competitive global economics.
We reject the bloated overhead of traditional agencies. By leveraging Vietnam's premier tech talent pool, we deliver enterprise-grade architecture at highly competitive development costs.
Tailored Team Composition
You pay for the exact engineering roles your sprint requires—no administrative bloat or unnecessary agency overhead.
Zero Legacy Debt
Clean code and scalable architecture mean you spend your budget on new features, not fixing future maintenance issues.
Direct Communication
Direct access to technical leads ensures complex business requirements are never lost in translation between account managers and developers.
Proof of Execution
Don't just take our word for it. Experience what we've built.
We don't just write code for clients; we conceptualize, architect, and scale our own technology. Explore our flagship B2B platform to see our UI/UX, database architecture, and performance standards in action.

Objection Handling & Transparency
Questions answered before you start.
Custom software depends on your scope, integration requirements, and security needs. During discovery, we break down your requirements into transparent engineering sprints and deliverables, ensuring you only pay for what your system actually needs.
Yes. We frequently conduct code audits, refactor legacy monolithic architectures, fix performance bottlenecks, and add modern APIs to existing systems without interrupting daily operations.
You retain 100% ownership of all written source code, database schemas, and architectural assets upon project completion or sprint delivery.
Every project goes through automated testing pipelines, peer code reviews, continuous integration (CI/CD) checks, and security audits before moving to live production environments.
Yes. We offer continuous SLAs covering cloud monitoring, security updates, bug fixes, and feature enhancements so your platform scales seamlessly.
