Learned by
building
I'm Wilson. I focus on building practical software that supports business operations, connects applications with infrastructure, and makes complex workflows easier to manage. My work spans full-stack development, desktop applications, networking, and system integration.
I am a self-taught developer who learns by designing, building, testing, and improving real-world solutions. I enjoy working across the software stack, exploring new technologies, and understanding how different systems work together.
Tools I use most
- React & Node.js
- MongoDB & Docker
- MikroTik RouterOS
- FreeRADIUS & WireGuard
- C# / .NET (WPF)
- C++ & ESP8266
Keep it running
Billing cycles, router syncs, kiosk sessions — the platform has to run every day on its own.
Own the whole stack
From React components to RouterOS scripts to ESP8266 firmware — I'd rather understand every layer.
What I work with
Web & APIs
Building responsive applications, APIs, and real-time services.
- React (Vite)
- REST APIs
- Socket.io
- MongoDB / Mongoose
- JWT auth
- Helmet
- Rate limiting
Languages
JavaScript first; C# and C++ when needed.
- JavaScript
- C# (.NET 8)
- C++ (Arduino)
DevOps
How I deploy and run things.
- Docker Compose
- Nginx
- Git / GitHub
Networking
Routing, wireless, and real-world connectivity, routing, and infrastructure environments.
- MikroTik RouterOS v6 / v7
- Ubiquiti
- Fiber deployment
- PPPoE / IPoE
- Bandwidth mgmt
- FreeRADIUS
- WireGuard VPN
Hardware & IoT

Building across systems
I enjoy building practical software that solves real-world problems. My work spans business applications, network infrastructure, desktop software, automation, and connected devices — with an emphasis on making complex systems reliable, useful, and easier to manage.
Business & Operations Software
Applications that streamline everyday operations, from customer and account management to billing, reporting, inventory, and workflow automation.
Networking & Infrastructure
Network services and management tools involving ISP operations, MikroTik, hotspot access, authentication, remote connectivity, and managed environments.
Desktop & Productivity Apps
Purpose-built desktop applications for business workflows, data management, productivity, and systems that connect software with day-to-day operations.
Embedded & Linux Systems
Exploring lightweight Linux environments, single-board computers, hardware integration, system services, and purpose-built computing solutions.
Automation & System Reliability
Integrations, background services, monitoring, access controls, and automation that help software and infrastructure operate consistently.
Community & Game Development
Custom server-side features, administration tools, and gameplay systems designed to support engaging and sustainable online communities.
A practical approach to building
Understand the problem
Start with the people, workflow, and constraints before choosing a technical solution.
Connect the pieces
Bring applications, devices, networks, and services together into a cohesive experience.
Improve continuously
Build, test, learn from actual use, and refine the details that make systems dependable.
Keep it usable
Prioritize maintainability and clear experiences that make everyday work easier.
How I build
-
01
Understand
Start with the actual problem — how subscribers pay, how routers behave, how people really work day to day.
-
02
Prototype first
Get a rough version running fast, with AI as a pair programmer. Cheap to throw away, quick to learn from.
-
03
Build end to end
Frontend, API, database, networking — even firmware when needed. One coherent system, not scattered pieces.
-
04
Ship & iterate
Dockerized deploys, tests where they matter most, then keep refining from real usage.
