Senior-Level Security & Performance

Worried about a slow or vulnerable site? With Cloudflare and enterprise-grade security, we build sites that don't just run — they're built to be secure.

  • DDoS protection
  • SQL injection prevention
  • Loading speed optimisation

Local Consultation in Sydney

Not the same as email-only overseas freelancers. Meet across Sydney — we listen to your business goals and recommend the right tech stack.

  • Face-to-face across Sydney
  • Tech recommendations based on your goals
  • Korean & English

AI can write code — but it won't take responsibility for your business stability.

We use AI as a tool to double development speed, while a senior engineer personally guarantees 100% of security and maintenance responsibility.

Developer in the AI era — ATech Systems

Case Studies

Challenge — Solution — Result

AU Fintech / Remittance Platform

Challenge

Only a decade-old legacy system existed; everything was manual. Client needed to align with strengthening Australian regulation (AUSTRAC, AML/CTF) and deliver a user-friendly remittance UI.

Solution

Discussed requirements and regulatory approach with stakeholders, then proceeded to contract. Rebuilt with security-first architecture, real-time FX API integration, KYC system integration, and remittance process automation.

Result

Delivered end-to-end from stakeholder alignment and contract through design and development. Regulatory compliance maintained while shifting from manual processing to automation for greater operational efficiency.

EdTech Platform — Lead Developer

Challenge

Schools and institutions needed multiple releases—mobile app, parent portals, security enhancements—while reducing support load and improving operational stability.

Solution

Core features including mobile app, media management, parent portals, and security enhancements. RESTful API design on a Web Framework; reusable, performant code for scalability; PostgreSQL, SQL, and Solr for data layer and audit compliance; standardized release and operating procedures.

Result

Managed, maintained and improved the overall architecture of the on-premise platform; established stable CI/CD and stronger customer communication, reducing support tickets by more than half. Drove stable platform operation and sustained service improvement.

Tech Support & Security — Enterprise Maintenance

Challenge

Businesses needing ongoing maintenance and security. Issues included frequent downtime, exposed vulnerabilities, and performance degradation on the existing web server.

Solution

Monthly security updates and patching; Cloudflare enterprise setup and server redundancy for availability. Regular security audits and performance optimization to maintain stable operation.

Result

99.9% uptime achieved, 2x faster page load, and reduced operational burden through ongoing security and performance management.
