Building an ecosystem
of practical AI products.
I'm John Prakash (JP), founder of Sentira AI — an ecosystem of AI products for learning, careers, creativity, and personal growth.
I learn by shipping. Every product goes public early, gets used, gets feedback, and improves the next week. Nothing sits in a folder waiting to be perfect.
Long-term, I'm building Sentira into a home for practical AI — a place where each product stands on its own but the ecosystem is worth more than the sum of the parts.
What I've actually shipped.
Real, live products. Click any card to explore the problem, features and tech behind it.
A growing ecosystem of AI products.
A collection of AI tools built for students, creators, professionals, and lifelong learners — each solving a practical problem.
Sentira AI
Sentira AI is a collection of practical AI tools I built for education, productivity, creativity, career growth, publishing, personal development, and knowledge management. Each product solves a specific problem I noticed in my own work or studies.
Learning by shipping real products.
I enjoy building AI products that solve practical problems. Each product in the Sentira AI ecosystem explores a different area such as emotional support, career development, learning, productivity, publishing, and knowledge management. My goal is to continuously learn, ship, and improve through real-world product development.
Where I spend my building energy.
How I actually build these products.
Engineering deep-dives — the problem, the architecture, the tradeoffs, the results.
Each Sentira product was a separate app with its own login, design, and billing. Users wanted a single home; I needed one place to iterate.
Studied how Vercel, Linear, and Notion structure multi-surface products. Interviewed early testers about the friction of switching between tools.
TanStack Start SSR shell → unified auth → per-product route sub-apps → shared AI Gateway → Supabase (Postgres + RLS) → per-user memory layer.
- Server functions over edge functions for app-internal logic
- Row-Level Security on every table from day one
- Design tokens instead of hardcoded colors so all products stay on-brand
- Isolating product routes while sharing auth, theme, and memory
- Streaming AI responses over SSR without hydration mismatch
- Keeping cold starts sub-second on the Edge
- Reduced auth-and-boilerplate work for new products from days to hours
- Shared memory layer live across 3 products
- 8 products shipped under one ecosystem
- Gemini 2.5 Pro
- Gemini 2.5 Flash
- OpenAI GPT-4.1
- Groq Llama 3.3 70B
- Cross-product agents that hand off context
- In-platform billing and team accounts
- Public API for external Sentira integrations
What I bring to every product.
A senior-shaped engineering surface — auth, data, AI, deployment, performance, and security — reused across the ecosystem.
One stack. Every product.
A shared architecture powers the whole Sentira ecosystem — so shipping the next product is measured in hours, not weeks.
Every arrow is a real wire in production — auth flows through server functions, AI streams through the gateway, and data lives behind RLS.

How I build products.
A repeatable loop that turns an idea into a shipped product without losing quality.
Building step by step, year by year.
Completed BCA & Explored Career Paths
Completed Bachelor of Computer Applications at Dr. R.K.S College of Arts and Science. Spent time exploring technology, AI, software development, and identifying the areas I wanted to pursue long-term.
Started MCA in Generative AI & Began Building
Joined SRM Institute of Science and Technology (SRMIST) for MCA in Generative AI. Started learning by building real-world applications, experimenting with AI tools, full-stack development, and product design.
Built the Sentira AI Ecosystem
Launched Sentira AI as a growing ecosystem of AI-powered products. Shipped platforms focused on emotional support, career development, academic productivity, publishing, knowledge management, and personal growth.
