You don’t need another developer.
You need someone who can build systems that don’t break when your business grows.
And for that, you need one thing: 𝐑𝐄𝐋𝐈𝐀𝐁𝐈𝐋𝐈𝐓𝐘.
That’s where I come in.
I turn your ideas into scalable, secure, and production-ready applications, not just code that works today, but systems that keep working as you grow.
I help startups, founders, and businesses who are tired of:
• Buggy applications
• Slow performance
• Developers who disappear mid-project
● Here’s what I do:
💡 Build full-scale mobile application using Flutter, Swift, Dart etc
💡 FireBase, MongoDB, APIs, Swagger, Stripe Integration, Twillio
💡 Develop secure, high-performance APIs that scale with your users
💡 Create modern, responsive UI/UX
💡 Optimize and fix existing systems (speed, bugs, structure — all of it)
💡 Turn complex requirements into clean, maintainable architecture
● My clients don’t just get code.
They get:
⚡ Applications that handle real users without crashing
⚡ Systems that are easy to scale and maintain
⚡ Clean architecture that saves time and money long-term
⚡ A developer who actually communicates and delivers
𝐁𝐞𝐜𝐚𝐮𝐬𝐞 𝐢𝐧 𝐫𝐞𝐚𝐥 𝐩𝐫𝐨𝐣𝐞𝐜𝐭𝐬…
Bad code is expensive.
Slow systems lose users.
and unreliable developers cost you more than money.
● So you’ve got two choices:
1️⃣ Keep patching issues and dealing with unstable systems
2️⃣ Build something solid, scalable, and future-ready
If you’re ready for the second,
send me a message. Let’s build it right the first time. 🤝🚀

I build AI-powered mobile apps and automation workflows for founders
who need to ship fast.
Most of my recent work is helping non-technical founders and small
teams turn an AI idea into a working product — chatbots, AI assistants,
n8n automations, OpenAI/Claude integrations, and Flutter mobile apps
with intelligent features baked in.
What I've built recently:
• OpenClaw integrations — multiple active projects covering setup,
memory configuration, browser integration, and Mac automation in
Shell/Node.js. Recent client: "strong knowledge on AI and
technical problem solving."
• Mentot — WhatsApp chatbot for virtual assistance, deployed
end-to-end
• Tailor AI — AI fashion recommendation app built in Flutter
• n8n automations connecting AI models to real business workflows
• Flutter + Firebase apps with real-time data and clean architecture
How I work:
• Clear scope before we start — no surprise hours
• Daily updates if the project runs more than a week
• Comfortable jumping on a Zoom call to align (book one below for $20)
• I work US-friendly hours when projects need it
I'm associated with TATOS Technologies, a Kerala-based product team
that ships AI MVPs in 2-week sprints. For larger projects ($10K+) I
can bring in design, backend, and QA support from the team. For
smaller scoped work, you get me directly.
