solo dev, real clients, no agency in between
I'm Sean Chin. VeloStack is my one-person software studio in Singapore, building custom platforms and workflow automations for businesses that can't wait months for working software. No account managers, no agency overhead. Just the stack, moving.
/ 01 · Things I've built
These aren't mockups. Every preview below is the actual deployed app, embedded live from Vercel. Click or hover to inspect.
On-set expense logger & margin center
A production finance platform for film and video teams, built around a single PIN-secured workspace: OCR receipt capture, live budget burn, mileage sync, call sheets and GST-ready client invoicing.
Built for Komo Social
✦ Launch client partnership
The all-in-one dashboard for Singapore tutors
Most tutors here still run their business off WhatsApp chats and a spreadsheet. TutorDesk gives them one dashboard for students, scheduling, lesson tracking and billing, so admin stops eating into teaching hours.
Personal wealth, decoded
A portfolio dashboard for investors who are tired of guessing. Allocation, performance and exposure update in real time, so decisions come from the numbers instead of a gut feeling.
Quantitative edge, on demand
A research workspace for traders who need an edge fast. Screening, signals and research workflows all live in one place, so you're not hunting across ten browser tabs.
/ 02 · How I work
Every build starts with deep alignment on your business workflow. We identify bottlenecks, plan database schemas, and lay out exact user journeys so we build only what drives concrete business outcomes.
No guessing or waiting months. I build and ship functional prototypes within days. You'll click through the interfaces, test the core flow, and provide feedback on the real product immediately.
Once the prototype is validated, I build the production system. We establish secure user authentication, reliable data schemas, and isolated database instances to ensure your product runs securely.
We deploy to high-availability global edge servers on Vercel. I handle the production infrastructure, launch checklist, and ongoing feature updates so your business software stays fast and reliable.
/ 03 · What I build
Dashboards, portals, SaaS products and internal tools, designed around your exact workflow instead of forcing your business into off-the-shelf software.
Kill the repetitive admin. I wire your tools, data and documents into automated pipelines that run while you sleep: invoicing, reporting, syncing, chasing.
End-to-end platforms with isolated databases, secure auth and production infrastructure. Built carefully, owned entirely by you.
/ 04 · Why VeloStack
I could hire a bigger team and add a few layers between us, but I don't think you'd get better software for it. Working solo just means lower overhead, faster answers, and you always know exactly who's building your product.
Same brief. Two ways to build it.
First working demo
Production launch
Cost structure
Data isolation
Who you talk to
Iteration after launch
Tell me about it. I'll scope it, sketch the architecture, and show you a working demo fast. You'll be talking to the person actually writing the code, not an account manager relaying messages between you and the people who do.
