Hi everyone,

I'm a full-stack software engineer based in Kenya with over five years of experience building and deploying production web applications. I'm currently available for freelance, contract, part-time, or full-time remote opportunities.

Tech stack:

React, Node.js, TypeScript, .NET/C#, Python

PostgreSQL, SQL Server

AWS (ECS, RDS, ALB, CloudFront, S3, IAM, CodePipeline)

Docker, Terraform, GitHub Actions, CI/CD

Some of the work I've done includes building full-stack SaaS applications, payment gateway integrations, AI-powered features using Gemini and Azure OpenAI, and designing a self-hosted Supabase platform on AWS with authentication, API gateway, storage, realtime services, and automated deployment pipelines.

I'm comfortable working across the entire stack from frontend development and backend APIs to cloud infrastructure and deployments and I enjoy working closely with clients and small engineering teams to turn ideas into reliable products.

Availability: Freelance, fixed-price projects, contract, part-time, or full-time

Rate: $20–35/hour (depending on the project)

Timezone: EAT (GMT+3), with flexible overlap for US and European teams.

If you think I might be a good fit for your project, feel free to send me a message. I'm happy to share my CV, GitHub, or examples of my recent work.

Hi,

I'm a C# dev for ~7 years now.

C#, WPF, linq, sqlite,...

I'm trying to get into contributing to open source Github repos.

I'm struggling with finding interesting things with open issues.

I never contributed yet nor worked with Github (as my company uses another scm).

Anyone of you working on cool open source software that still needs help and is forgiving mistakes with the contribution process for a short period (fast-learner usually)?

Edit: [PAUSED] Hey! Thank you so much for all the responses! I honestly did not expect so many of you reaching out so quick! It will take me a minute to go through the messages and check out your portfolios!
