What we do

End-to-end software,
built to last.

We don't have departments. We have depth. Every engagement is handled by engineers who've shipped in production, led teams, and carried the responsibility of a CTO.

Web & Mobile Development

Full-stack applications built for scale: from MVPs that validate ideas to production systems that handle real load. Clean architecture, tested, and built to be maintainable.

  • Vue
  • Angular
  • React
  • TypeScript
  • NestJS
  • Go

Fintech & Financial Systems

We've operated at the intersection of software and money for over a decade. Payments, core banking integrations, compliance tooling, and audit-ready systems built under regulatory scrutiny.

  • Core Banking
  • Payment Rails
  • Compliance
  • Risk Systems

CTO & Tech Leadership

Fractional CTO engagement, architecture review, hiring strategy, and team structuring. We've been in the seat and we know what it costs a business when this role is vacant or filled wrong.

  • Fractional CTO
  • Architecture
  • Team Building
  • Tech Strategy

Cloud & Infrastructure

Infrastructure-agnostic by design. We architect and operate on AWS, GCP, and Azure without vendor lock-in. Containerised deployments, CI/CD pipelines, observability, and cost-efficient cloud that scales with your business.

  • AWS
  • GCP
  • Azure
  • Docker / Kubernetes
  • CI/CD
  • Monitoring

Security Engineering

Security is baked in, not bolted on. We design and review systems against the OWASP Top 10, implement secure coding practices, conduct threat modelling, and help engineering teams build a security-first culture from day one.

  • OWASP Top 10
  • Threat Modelling
  • Secure Code Review
  • Pen Testing
  • Auth & Access Control

AI Automation

We integrate AI into real workflows. From intelligent document processing and LLM-powered pipelines to agentic systems that replace repetitive manual work. Practical AI that ships, not demos that impress and then collect dust.

  • LLM Integration
  • Agentic Pipelines
  • RAG Systems
  • Workflow Automation
  • AI APIs

Who we are

Small team.
Senior minds.

RXJR Dev Studio is intentionally small. Two engineers. No account managers, no juniors assigned after the handshake. When you work with us, you get the people who spent 16 years in production environments, regulated industries, and high-stakes product decisions.

One of us led engineering as CTO at a financial company in the Philippines, navigating compliance, scale, and organisational complexity. The other brought that same rigour to Australia's fintech scene, working on infrastructure backed by ANZ Ventures and NAB Ventures, two of the most consequential banking groups in the region.

We don't believe in project hand-offs to whoever is free. We believe in ownership, craftsmanship, and software you're not embarrassed to grow into.

→
Direct access You'll always talk to the engineer doing the work.
→
Regulated industry experience We understand compliance, audit trails, and risk.
→
No over-engineering We build what the problem needs, not what looks impressive.

How we work

Straightforward process.
No surprises.

01

Discovery

We start by understanding your problem, not just your spec. One or two focused sessions to map the landscape: technical constraints, business model, timeline, risk tolerance.

02

Architecture & Scoping

Before a line of code is written, we design the system. You get a clear picture of what we're building, why, and what trade-offs we're making. No black boxes.

03

Iterative Build

We work in tight cycles. You see real software early. We adjust as we learn. No six-week blackouts before a demo. Feedback loops are part of the process.

04

Handoff & Support

When we're done, you own it. Full documentation, tested code, and a knowledge transfer so your team isn't dependent on us to keep the lights on.
