Your tools don't talk to each other. Let's fix that.

I build custom internal dashboards that connect your existing systems like payments, bookings, data, and workflows into one place your team can actually use.

Migrolino IMS

Internal ops platform for a 300+ location Swiss franchise network

Stack
MongoDBExpressReactNode.js
Problem

A 300+ location Swiss franchise network was managing store operations through email and disconnected tools. Support tickets, events, documents, and surveys were spread across systems with no single source of truth and no visibility into what was resolved or pending.

Build

Built a multi-role internal ops platform from scratch. It includes structured issue ticketing with categories, urgency levels, file attachments, and full lifecycle tracking, along with modules for event registration, document sharing, and user administration. The platform supports German, French, Italian, and English across regions.

Result

Replaced fragmented email workflows with a centralized system used across the full Migrolino franchise network. Every ticket is tracked, every status is visible, and teams no longer need to chase email threads.

Multi-role studio reservation platform with payments and credit system

Stack
MongoDBExpressReactNode.jsStripe
Problem

A Swiss recording studio was managing bookings manually across three studios. There was no way to enforce pricing rules, handle cancellations consistently, or give members visibility into their credit balances without staff involvement.

Build

Built a multi-role studio reservation platform with a credit-based payment system integrated with Stripe and TWINT. Implemented per-studio, per-slot pricing logic, rescheduling fees, partial credit refunds on cancellation, and a full admin panel for user management and pricing configuration.

Result

Booking, payments, and capacity management are fully automated. There is no manual scheduling, policies are enforced consistently, and members and engineers have self-service access.

About

Turning product ideas
into clean systems.

Vin Le, Full-Stack Engineer

I’m a full-stack developer who builds internal tools and operational systems for small businesses that have outgrown off-the-shelf solutions. Many businesses start with Airtable, Notion, or a mix of SaaS tools, then hit a wall when their workflows become too specific or the monthly costs start adding up. I build a single system that connects everything, fits their exact process, and is fully owned by them.

Currently, I'm the sole frontend engineer at Zinc, where I'm building an AI-driven business analysis platform. My work spans UI architecture, data visualization, API integration, and backend systems with Django and PostgreSQL.

My path to engineering is unconventional. I spent a decade as a professional photographer, then moved into digital marketing before teaching myself to code. That background shapes how I work. I think about users, systems, and aesthetics together, not separately.

I'm based in Vietnam and take on a small number of focused projects.
