About Romantic Developer
I am Romantic Developer, a software creator building mobile-first systems that are
scalable, secure, and made for real people. I have delivered products across eWallet,
eCommerce, games, fintech, online payment, booking, news, and CMS platforms.
From architecture strategy to hands-on implementation, I help teams turn ambitious
ideas into reliable software ecosystems that evolve feature-by-feature instead of
rewrite-by-rewrite.

Frequently Asked Questions
What problems do your services solve best?
I help teams clarify architecture, accelerate delivery, strengthen mobile security, and turn product ideas into stable systems that can grow with the business.
Do you only advise, or do you also get hands-on?
Both. I can lead as a fractional CTO, review the technical direction, or work directly on critical delivery areas when execution needs extra depth.
Which technologies and stacks do you usually work with?
My core stack includes Flutter, Kotlin Multiplatform, native Android and iOS, Spring Boot, FastAPI, ReactJS, NextJS, and modern cloud delivery tooling.
Can you help us if we already have an existing product?
Yes. I often start with an architecture review or modernization plan so the current product can improve without forcing a risky rewrite.
Do you support security and AI-related initiatives too?
Yes. I provide mobile security audits, delivery guardrails, and AI product advisory for teams that want to adopt smarter workflows with control and clarity.
How do clients usually start working with you?
Most engagements start with a focused conversation about the bottleneck, then I recommend the right path: review, fractional leadership, delivery acceleration, or a tailored engagement.
Do you work with non-profits and open-source projects?
Yes, absolutely. I support non-profits, open-source initiatives, and community-driven projects.
What does "Coffee | Beer" pricing mean?
Flexible, informal pricing for non-profit and open-source initiatives—mentoring, code review, or strategic guidance.
What types of non-profit and OSS projects do you support?
Educational platforms, health tech, financial inclusion tools, developer tools, and community platforms with genuine social impact.
