I help companies modernize backend systems and scale cloud infrastructure.
I specialize in architecture modernization, reducing technical debt, and building reliable cloud-native systems that handle real-world scale, without disrupting production.
I work on the architecture level, where real performance, reliability, and scaling decisions are made.
Features don’t usually kill momentum. Systems do.
“The issues that slow growth, damage trust, and cost money.”
How I can help you
High-impact backend, cloud, and system engineering focused on reliability, scalability, and cost efficiency.
Deep analysis of backend architecture, database performance, API design, and bottlenecks with a clear engineering roadmap for scale and stability.
Re-architect legacy systems into scalable cloud-native solutions with improved reliability, deployment speed, and cost optimization.
Safe migration of legacy monoliths, databases, and authentication systems with zero production disruption and rollback strategies.
Long-term engineering ownership for startups: system design, backend architecture decisions, performance tuning, and cloud cost control.
Products shipped in production
Real projects, measurable outcomes. These aren't mockups - they're live systems handling real users.
Redesigned the real-time communication layer for Pickles Asia's vehicle auction platform. Architected a horizontally scalable solution on AWS ECS with a pub-sub mechanism for live bidding across thousands of concurrent users.
Built a scalable data aggregation server integrating Instagram, YouTube, and TikTok APIs via a queue-based architecture. Delivered 98% accuracy and uptime with GDPR-compliant data processing for a French social intelligence platform.
Migrated Pickles Asia's authentication from session-based to JWT, eliminating CSRF vulnerabilities and scaling limitations. Achieved 100% backward compatibility across the mobile app, web app, and backend with zero session-related issues post-launch.
Led a team of 9 to design and build an in-house QA automation platform from scratch in 3 months. Implemented a full CI/CD pipeline with GitHub Actions and AWS, dramatically cutting manual testing overhead.
Systems Engineering Capabilities
Focused on building scalable backend platforms, modern cloud infrastructure, and production-grade systems that grow with business demand.
How I work
A structured approach that keeps projects on track, in scope, and shipped on time.
Deep dive into your product goals, constraints, and user needs
Architecture planning, tech stack selection, and system design docs
Iterative development with weekly demos and clean, tested code
Zero-downtime deployment with monitoring, alerting, and rollback
Ongoing maintenance, performance optimization, and iteration
I'm a Senior Backend & Cloud Engineer based in Cyberjaya, Malaysia with 7+ years building real-world systems that scale. I specialise in SaaS products, real-time architectures, and legacy system modernisation.
Every project I take on, I treat as if it were my own. That means caring about performance, reliability, and long-term maintainability - not just shipping features. I've led engineering teams, architected microservices handling millions of daily transactions, and delivered zero-downtime migrations on 6+ year-old systems.
When I'm not building, I write about engineering strategy on my Substack.
What clients say
Trusted by startups and enterprises globally - 100% job success.
“Dulan is one of the best among all the people I have ever worked with. He is not only a multi-skilled and insightful colleague, but also an inspiring friendly person who's open to help others at any given time under any circumstances. His ability to listen and understand the clients' needs allows him to engineer any software solution effectively. He leads by example and is a trusted colleague.”
“I had the pleasure of working with Dulan for 7 months, and he consistently delivered high-quality work while respecting deadlines. As a key team member Dulan contributed to the successful development of an MVP, while coping with the challenges of changing requirements and tight deadlines. He is friendly, always open to suggestions, and has a great ability to listen and understand client needs. I highly recommend Dulan.”
“Dulan's presence has been beneficial to my team. He contributed significantly to our projects and demonstrated a high level of full-stack development, TypeScript, React, and NestJS technical proficiency. He has worked on several projects, and I was impressed by his work ethic. He exhibits strong analytical skills and a desire to advance both personally and professionally.”
