Built by one operator, in the Greater Toronto Area.

I'm Kaustubh Ghodke. I've been writing frontend code for about ten years — most of it shipping production interfaces at agency speed for clients who expected the work to look as good as it ran. DigiCatalyst Systems is the practice I run as a sole proprietor under Ontario Master Business Licence, operating across the Greater Toronto Area.

The reason DigiCatalyst exists is one observation, repeated across every contractor I talk to in the GTA: the phone is the bottleneck. HVAC, plumbing, roofing, electrical — owner-operators answer their own calls, miss most of the after-hours ones, and pay for ad clicks that go to voicemail. The math is brutal once you actually run it. A1 (missed-call SMS recovery) is the productized fix.

The systems are built with Claude (the AI assistant), n8n (the workflow runner), Twilio (SMS), and Cal.com (booking). I write every line of the question scripts. I tune them per trade. I do the Twilio A2P 10DLC compliance work. The Friday inbox report is rendered from real call data, not a templated dashboard. Adjacent niches I've already started conversations with — med spas, mortgage brokers, used-car dealers, immigration consultants (RCICs) — get their own productized variants when there's enough signal to justify a sub-page.

Coming next: A2 (voice receptionist), A3 (no-show recovery), A4 (review response), A5 (lead-qualification chatbot). All four ship in Q3 2026. The roadmap is intentional and slow. I'd rather ship one thing that pulls real revenue for one trade than five half-built tools that look good in a deck.
