Reliable Full-Stack Developer & AI Developer Expert
I'm Alan Ari Mahendra, a fullstack developer building custom ERP, CRM, and web systems, the workflow automation that connects them, and AI chatbots and LLM-powered features that plug straight into existing data, for teams across the US, Australia, and Europe. Over 3+ years and 38+ production projects, I own the full stack end-to-end, from database schema to deployed UI, so there is no hand-off gap between building a feature, automating it, and keeping it reliable once real users arrive.
Tech I work with
Built to slot into your team
Custom Automation Workflow
Connecting your tools and eliminating repetitive manual work with workflows tailored to your operations.
AI Chatbots
Conversational assistants for support, sales, or internal ops, wired directly into your existing systems and data.
Code Audit, Refactor & Scale-Up
For vibe coders and non-technical founders who shipped fast with AI tools: I audit what’s there, refactor the fragile parts, and get it ready to handle real users.
Custom ERP, CRM & Web Development
Management systems, CRMs, and web platforms built around how your business actually runs, not a rigid off-the-shelf template.
Custom Payment Integration
Stripe, Midtrans, and other gateways wired into checkout, billing, and subscription flows so money moves without manual reconciliation.
Hire hourly or monthly
Scoped task or a quick fix? Go hourly, starting at $15/hr. Ongoing work or a full build? A monthly retainer fits better.

What it's like to work with me
Frequently asked questions
What kind of projects are the best fit?
Custom ERP/CRM and web platforms, automation workflows, AI chatbots, payment integrations, and audits of AI-generated codebases that need to survive real production traffic.
How does an engagement usually start?
Send a project brief or the codebase in question. I come back with a clear read on fit and approach within one business day, then we scope it on a short call.
Do you work with clients in the US, Australia, and Europe?
Yes, most of my clients are there. I’m fluent in English, communicate written-first, and I’m based in Semarang (GMT+7): same working day as Australia, morning overlap with Europe, and evening overlap with the US, so no one’s ever waiting long for a reply.
Got something worth building, or fixing?
A couple of sentences about what's going on, plus a link if there's a repo or live site, is enough for me to tell you if I'm the right person for it.
