From intern to CTO: building the suite

Rahtsaa AI, July 2025 to now. Full-time, from the first internship week to the CTO role.

I joined as an intern in July 2025, working on AI/ML setup, an AI accounting agent, backend and database work and technical research. In October 2025 I became Founding Engineer and in September 2026 CTO. The whole way, this has been my full-time effort.

The company started as a single software product built for chartered accountants. My vision, and the work to make it real, is to turn that into a suite: one platform that handles marketing, sales management, accounting and compliance, so a business can run on one system instead of stitching tools together.

The path

  1. InternJul 2025 to Sep 2025
    Completed

    Joined and shipped on AI/ML and backend

    AI/ML setup and management, AI Accounting Agent development, machine learning model implementation, backend, database management and technical research.

  2. Founding EngineerOct 2025 to Aug 2026
    Completed

    Took ownership of the technical roadmap

    Continued the AI accounting agent, backend and database work, and began leading the technical roadmap, architectural oversight, code review, documentation systems and release governance.

  3. Chief Technology OfficerSep 2026 to present
    Now

    Leading the suite

    Roadmap, architecture and quality governance, engineering workflows, team performance and hiring, cost control and client technology onboarding.

  4. Product vision
    Vision

    From one CA-based product to a suite

    The aim is a single suite handling marketing, sales management, accounting and compliance, grown out of the original CA-focused software. Accounting is the area with documented AI work so far (the AI Accounting Agent); other modules are the direction of travel.
