Phuket, ThailandSoftware developer in Phuket, Thailand
I'm Sim Kritamook, a freelance software developer based in Phuket. I build booking systems, internal tools, dashboards, and custom business software for companies here on the island and for remote teams. Finding a software developer in Phuket is harder than it looks. The island has plenty of people who can put a website online, but far fewer who can take a real business workflow — reservations, payments, staff schedules, commissions — and turn it into software that holds up once it is in daily use.That gap is what I work on. I have spent over seven years building digital products, and the projects I take on now are the ones where the software has to run the business, not just describe it.
What I build
Booking and reservation systems
Customer-facing booking flows, availability logic, payments, and the admin side that staff actually use every day.Internal tools and admin dashboards
Software that replaces spreadsheets, LINE threads, and paper notebooks with one place your team can trust.Custom web applications
Full-stack builds from database design through to the interface, delivered as a working product rather than a prototype.Reporting and operations software
Revenue reports, commission tracking, and workflow automation that turn day-to-day data into something usable.Why work with a developer who is actually in Phuket
Software for a local business has to fit how that business really operates: Thai bank transfers, LINE as the main customer channel, high season and low season, staff who need the interface to be obvious. A developer who lives here does not need those things explained.It also means the same time zone, the option to meet in person when a project needs it, and someone who is still around after launch — which is where most local software projects quietly fall apart.How I work
1. Understand the workflow
We walk through how the business runs today and where the manual work, double bookings, or missing numbers actually come from.2. Scope something deliverable
I cut the work down to the version that solves the real problem first, with a clear timeline, rather than a specification that takes a year to finish.3. Build in visible increments
You see working software as it is built, so feedback arrives while changes are still cheap.4. Launch and keep it running
Deployment, handover, and ongoing support, so the system keeps working after the project ends.See the work
The clearest picture of how I build is the software itself. A badminton court in Phuket replaced LINE-based bookings with a full reservation and payments system; other projects cover commission tracking and match management.Frequently asked questions
Are you a software developer based in Phuket?
Yes. I live and work in Phuket, Thailand, and I work with businesses across the island as well as with teams elsewhere in Thailand and abroad. Local clients can meet in person; remote clients work with me over calls and shared project tooling.What does a software developer in Phuket typically build for local businesses?
Most of the demand here comes from tourism, hospitality, sports facilities, property, and service businesses. That usually means booking systems, customer management, staff admin panels, payment handling, and reporting tools rather than large enterprise platforms.Do you work in English or Thai?
Both. Project discussions, documentation, and delivery can happen in either language, which matters when a business has Thai-speaking staff and English-speaking owners or investors.What technology do you build with?
Mainly TypeScript across the stack: React and Next.js on the front end, Node.js services and SQL databases behind them, deployed on managed cloud platforms. The stack is chosen so the software stays maintainable after launch.Can you take over software that another developer built?
Yes. Picking up an existing codebase, stabilising it, and continuing feature work is a common starting point, especially for businesses whose previous developer or agency stopped responding.How do projects usually start?
With a short discovery call to walk through the current workflow and where it breaks down. From there I scope the work into something deliverable, agree on a timeline, and start building in visible increments.Looking for a software developer in Phuket?
