How I Created a Startup to Enterprise in One Weekend from scratch

Introduction

Creating a fully functional platform like an Enterprise SaaS in just one weekend might sound like an impossible task, but with the right tools, motivation, and a clear plan, it can be done. In this blog post, I’ll walk you through how I managed to build a Startup from scratch using Golang, Kubernetes, MongoDB, Neo4j, MySQL, and Redis.

The Motivation

The idea of a Startup Project had been brewing in my mind for a while. I wanted to create a platform that could handle complex data relationships, provide real-time updates, and scale effortlessly. With a free weekend ahead, I decided to take on the challenge and bring Startup Project 🔯 to life.

The Tech Stack

Here’s a quick overview of the technologies I used:

• Golang: For its performance and concurrency capabilities.
• Kubernetes: To manage containerized applications and ensure scalability.
• MongoDB: For its flexibility in handling unstructured data.
• Neo4j: To manage complex relationships between data entities.
• MySQL: For structured data storage.
• Redis: For caching and real-time data processing.

Day 1: Setting Up the Environment

Morning: Planning and Initial Setup

I started by outlining the core features and architecture of Project. With a clear plan in mind, I set up my development environment:

1. Installed Golang: Ensured I had the latest version of Golang installed.
2. Set Up Kubernetes: Deployed a local Kubernetes cluster from scratch, since back then, I started with beta, the installation were not that good.
3. Configured Databases: Set up MongoDB, Neo4j, MySQL, and Redis instances using Docker.

Afternoon: Building the Backend

With the environment ready, I began coding the backend in Golang:

1. API Design: Designed RESTful APIs for data operations.
2. Database Integration: Integrated MongoDB, Neo4j, MySQL, and Redis with the Golang backend.
3. Containerization: Created Dockerfiles for the backend service.

Evening: Deploying to Kubernetes

By the evening, I had a working backend. I deployed it to the Kubernetes cluster:

1. Created Kubernetes Manifests: Defined deployments and services for the backend and databases.
2. Deployed to GKE: Applied the manifests to deploy the application to Google Cloud Kubernetes Engine.

Day 2: Adding Features and Polishing

Morning: Implementing Core Features

I spent the morning implementing the core features of the Project:

1. User Authentication: Added JWT-based authentication.
2. Data Operations: Implemented CRUD operations for different data entities.
3. Relationship Management: Leveraged Neo4j to manage complex data relationships.

Afternoon: Real-Time Updates and Caching

In the afternoon, I focused on enhancing performance and real-time capabilities:

1. Real-Time Updates: Used WebSockets to provide real-time updates to clients.
2. Caching: Integrated Redis for caching frequently accessed data.

Evening: Testing and Final Touches

By the evening, I had a functional version of the Project. I spent the remaining time testing and polishing the application:

1. Unit Testing: Wrote unit tests for critical components.
2. Load Testing: Ensured the application could handle high traffic.
3. Documentation: Created documentation for the APIs and setup instructions.

Additional Details

Before building a Startup, I was a full stack developer and datacenter engineer at NTT PC in Japan. This experience provided me with the skills and knowledge needed to develop a Startup from the smallest CSS and HTML files up to scaling, building, deployment files to Kubernetes clusters across multiple cloud services, custom bash scripts that works like magic, DNS, registrars, code repositories, and securing our infrastructures.

This Project won't be possible w/o our good CEO. we started 3 amazing members in the company. our CEO played many different roles, developer, manager, sales, and a bit of infrastructure.

Conclusion

Creating a Startup in one weekend was a challenging yet rewarding experience. With the right tools and a clear plan, I was able to bring my vision to life. If you’re passionate about building something, don’t be afraid to take on ambitious projects. With determination and the right approach, you can achieve amazing things in a short amount of time.

I hope you enjoyed reading about my journey in creating a Startup!
