As the Chief Technology Officer at guidepe, I spearheaded the creation of a cutting-edge platform that revolutionized the way users hire guides and book packages in Northeast India. Leveraging Next.js, Hasura, and FastAPI, I led a talented team in developing innovative features to enhance user experience and streamline the booking process. Through strategic decision-making and a focus on user engagement, we achieved a remarkable 40% increase in platform bookings within the first year.

ABOUT RISHA SRINGA CHANGMAI
If you\'re raising or just raised for an AI-native product, you don\'t need another senior engineer — you need someone who has already built what you\'re trying to build.I\'m a fractional CTO for AI-native SaaS startups. 8+ years. Three CTO titles. My work has powered ed-tech at TopHat in Toronto, fintech payments on Substrate/Polkadot, and three e-commerce platforms still running years after delivery in North-East India.What I do for early-stage AI-native teams:→ Architect your LLM layer so you aren\'t locked to one provider. I\'ve implemented OpenAI, Anthropic, Azure OpenAI, AWS Bedrock, and OpenRouter behind a single interface in real code — not theory.→ Design safe tool execution for agents that touch code, shell, or customer data: Docker sandboxing, IAM isolation, path-traversal protection. One LLM with unsandboxed shell access is the production incident you don\'t want to explain to your investors.→ Build DAG-based workflow engines for anything beyond a single prompt — topological sort, parallel execution, error handlers, retries, hard timeouts. The right shape once your AI feature has more than two LLM calls.→ Integrate MCP so your customers can bring their own tools: stdio + SSE transports, namespaced tool routing, multi-server resilience.→ Ship to Cloud Run via Terraform from day one. Secret Manager, least-privilege IAM, zero manual ops lore.Past outcomes, with real numbers:• 75% server-runtime reduction via microservices (e-commerce, NE India)• 80% Google Maps API cost reduction (travel platform)• 40% increase in platform bookings within year one (GuidePe)• 8% payment-query speed improvement (Polkadot/Substrate integration)Stack: Node.js / NestJS · AWS · Python / FastAPI · Next.js · Flutter · SurrealDB · BullMQ · Docker · Terraform · OpenAI / Anthropic / Bedrock · Substrate / Ink!Current status: CTO at Creator24. Taking on one fractional engagement + one project alongside that role.How I work:• Architecture Audit — 2 weeks, fixed scope, diagram + risk register + 90-day plan• Fractional CTO Retainer — weekly strategic syncs, architecture, hiring, vendor review• AI Feature Sprint — 4 weeks embedded, ship one real LLM feature with evals + cost controlsBest fit: seed to Series A AI-native SaaS, within the first 18 months of building.DM me here or email r••••••••@icloud.com.
