Services & Expertise
I specialize in building intelligent systems at scale. From Qlik Sense extensions to enterprise AI voice agents, here's what I can help with.
An ANTLR-based Qlik → Power BI conversion engine and a voice platform on Asterisk and FreeSWITCH are the kind of systems I take on — the deep, compiler- and infrastructure-level work most product teams don't build in-house, delivered fast.

Schedule a CallFrequently Asked Questions
Quick answers about how we can work together
🔨Can you help with custom Qlik Sense extensions?
Yes! That's one of my core specialties. I've been building custom Qlik extensions with Nebula JS for years. Whether it's simple visualizations or complex interactive extensions, I can help. Check out my open-source Qlik Capability API (11,200+ combined npm downloads across my packages) for reference.
🔄How much does a Qlik to Power BI migration cost?
Migration costs depend on the number and complexity of apps. I've done migrations using ANTLR-based automated conversion. I can provide a detailed estimate after understanding your requirements. Let's discuss during a call.
⏱️What's the typical timeline for a Qlik extension project?
Simple extensions: 2-4 weeks. Complex interactive extensions with custom visualizations: 4-8 weeks. It depends on scope and complexity. We'll create a detailed project plan upfront.
🛠️Do you work on specific technologies only?
I specialize in Qlik Sense, Power BI, AI Voice systems, and modern web development (Next.js/React). If your project involves these areas, I'm the right fit. Available for freelance, consulting, and full-time opportunities.
👨🏫Can you help my team learn Qlik development?
Absolutely! I mentor developers and have led teams. I can provide code reviews, pair programming sessions, architecture guidance, or structured training on Qlik Sense extensions and best practices.
📚Where can I find your open-source tools?
My open-source packages are on npm and GitHub — search "ranjithm" on npm or visit github.com/ranvithm to explore. The Qlik Capability API and Qlik CLI packages are the most used.
💬How do we communicate during the project?
Flexible based on your preference. Could be regular sync calls, async updates via Slack, email, or a mix. For freelance projects, I'm responsive within 24 hours. We'll establish communication cadence upfront.
🤔What if I'm not sure exactly what I need?
That's normal. Schedule a consultation call and we'll explore your challenge together. I ask the right questions to understand your needs, constraints, and goals. Then I'll recommend the best approach.
