Project details
A poorly documented or inconsistently designed API becomes a support burden for every developer who uses it. I've built APIs for high traffic relay systems (MetroAPI) and multiple SaaS products. Every endpoint is consistent, every error has a meaningful response code, and every route is documented clearly enough that your frontend team can work independently from day one.

Next.js Developer to Deploy and Fix Production on Vercel
Triananda was the perfect freelancer for my problem! I was having trouble deploying my NextJS app in Vercel, and he was able to solve it perfectly. He also took the initiative to provide me with documentation of everything he did so I could operate GitHub, including CI/CD, in the future. I hope to work with him again in the future.

Job Success
Semarang, Indonesia - 1:38 pm local time
Over the past 5 years, I've built and maintained production systems, including multi-tenant SaaS platforms, CRM systems, event management tools, e-commerce platforms, and learning management systems, most from architecture through deployment.
Where I'm strongest:
- AI integration - OpenAI API, AI powered chatbots, intelligent automation workflows, and AI driven features inside existing products. I help teams add AI capabilities that actually solve problems, not just look impressive.
- SaaS application development - multi-tenant architecture, subscription logic, role-based access, API first design. I've built platforms handling real users and real transactions, not just demos.
- Fast, production ready delivery - I move quickly without shortcuts. Clean architecture, well structured code, proper deployment. Most clients are surprised by how fast the first working version lands.
Tech stack:
- Backend: Node.js, Express, JavaScript, TypeScript
- Frontend: React, Next.js, Vue.js, Nuxt.js
- Database: MySQL, PostgreSQL, MongoDB, Supabase
- Styling: Tailwind CSS, HTML, CSS, ShadCN
- Cloud and Tools: Vercel, AWS, Docker, GitHub, Firebase, CI/CD
- AI Tools: Claude, Copilot, Codex, Cursor, v0, Lovable, OpenAI API
If you're building a SaaS product or adding AI features to an existing application, send me a message with a short overview.
I'll tell you honestly whether I'm the right fit and how I'd approach it.
