What is CoSparq?
CoSparq is an AI-powered platform designed to help founders validate, build, and launch ideas faster. It combines agentic AI systems, real-world automation, and full-stack engineering to turn raw ideas into production-ready products—without the traditional friction of early-stage development.
Agentic Systems
Engineered a context-aware Agentic AI chatbot and voice Agent with persistent memory layered on top of stateless LLM APIs. The AI maintains long-term conversation context, user intent, and project state across sessions. Supports complex, multi-step reasoning instead of single-turn prompt responses.
The Purpose of CoSparq
Most founders waste time stitching together tools, validating ideas too late, or rebuilding the same infrastructure repeatedly. CoSparq centralizes ideation, validation, execution, and automation into a single AI-driven workflow—allowing founders to move faster with fewer resources and better technical foundations.
Technical: The Technologies I Used and What I Learnt
Building CoSparq required designing scalable AI systems, secure infrastructure, and cost-efficient workflows while integrating multiple external APIs. This project pushed me beyond simple LLM usage into full agentic system design and production engineering.
AI & External Service Integration
Backend & AI Architecture
Implemented Stripe subscriptions with tiered plans and secure webhook verification.
Built per-user API cost tracking across 15+ OpenAI models in real time.
Designed the system with security-first principles: JWT authentication, HTTP-only cookies, refresh token rotation, role-based access control, and API rate limiting.
