Portrait of Christian Angelo Umali

Christian Angelo Umali

I design, build and ship web platforms, mobile apps and agentic AI systems, hands-on, from architecture to release.

Book a callSelected work

9+ years of shipping software for teams in Australia, New Zealand, Singapore, Canada, United States and Philippines. The years run from 2017 to today, through Software Developer, Full Stack Developer, Senior Software Engineer and Lead Software Engineer & AI Engineer. The figures land: 300+ white-label storefronts, 1,000+ businesses served and a release cycle cut from 10 days to 4. The tools form a wall, React, Claude AI / Anthropic, Node.js, Supabase, AWS Lambda, React Native and Jest among them. An agent system draws itself: a prompt, the agents, their tools and a review gate. Project names flash past, PropApp first. It ends on the three headline figures and an invitation to book a call.

Questions, answered

Working With Me

Are you available for freelance projects?
Yes. I take on select freelance and contract projects where I can own meaningful outcomes - usually mobile apps, web platforms, or full-stack SaaS work. I am also open to the right long-term remote role.
What's your typical project process?
The process usually moves through discovery, architecture and planning, iterative development, QA, and launch. Communication stays clear and async-friendly, with regular updates and visible progress.
What types of projects do you take on?
The strongest fit is React Native mobile apps, React or Next.js web products, and full-stack SaaS systems. I tend to be most valuable on products that need production-quality code, scalable architecture, and end-to-end ownership.
How do you handle communication and updates?
I prefer clear async communication: Slack or Teams for day-to-day work, short Loom or written updates for progress, and weekly sync calls when alignment matters. The goal is visibility without noise.

Technical

What's your core tech stack?
My core stack is React Native and Expo for mobile, React and Next.js for web, TypeScript throughout, Node.js or Express for APIs, and Supabase or Firebase-backed services. PostgreSQL, GraphQL, Zustand, TanStack Query, and Tailwind are also common parts of delivery.
Do you handle deployment and DevOps?
Yes. I handle CI/CD with Fastlane, Bitrise, GitHub Actions, EAS, and modern web deployment flows. That includes app store submissions, Vercel or AWS deployments, and database migration workflows.
Can you work with my existing codebase?
Absolutely. Existing codebases are a normal part of the work. I usually start with an audit, identify quick wins and structural risks, then make changes incrementally so improvements do not break active delivery.
Do you provide ongoing support after launch?
Yes. Post-launch support can include fixes, performance monitoring, feature iteration, release support, and ongoing retainers depending on the product and how hands-on you want the relationship to stay.

If the work fits, let's talk.

I'm currently available for freelance projects and full-time opportunities. Let's discuss how I can help bring your web, agentic, or mobile product ideas to life.
