Mayantha did a great job on my git analysis project. He knows frontend development very well. His code was clean and he finished everything on time. Easy to work with and responds fast. The work was spot on given the small context I sent him and the project turned out to be amazing. Would hire him again for sure. Highly recommended! 5 stars.

Make.com AI-Powered LinkedIn Post Automation
Mayantha did an excellent job setting up a complete LinkedIn automation system for us using Make.com and OpenAI. He designed the entire workflow from content generation to automatic posting and added an approval step so we can review posts before they go live. The integration with LinkedIn, Airtable, and Google Sheets works perfectly, and the whole process runs smoothly without manual effort. His understanding of automation, AI, and APIs is impressive, and he delivered exactly what we needed on time. Highly recommended!
