Approach
Built for real projects, not brochure promises.
SMS is operational infrastructure
SMS looks simple from the outside, but production messaging needs logs, statuses, retries, provider boundaries, user feedback, and clear rules around when messages should be sent.
Useful messaging workflows
Common projects include OTP login, booking updates, attendance confirmation, lead follow-up, staff reminders, payment notices, and event-triggered customer communication.
Rails-friendly implementation
Rails can provide the API, background jobs, admin review, message history, user permissions, and reporting layer around the SMS provider or telecom integration.
Proof Points
Relevant background.
Built and operated IPROG SMS, an API-based SMS platform with telecom integrations.
Built IPROG DTR, an OTP-based attendance system for employee time tracking.
Experience connecting SMS workflows with Rails, APIs, webhooks, and business automation.
FAQ
Common questions.
Can you build OTP verification?
Yes. I can build OTP flows for login, attendance, verification, or transaction confirmation, including logs and sensible expiration rules.
Can you integrate an existing SMS provider?
Yes. If the provider exposes an API or gateway, I can connect it to a Rails app and build the operational screens around it.
Can SMS connect with AI or CRM workflows?
Yes. SMS can be part of AI follow-up, lead capture, reminders, or CRM-style automation when the workflow is mapped carefully.
