Hi, I’mJay Kanara.
I build backends, data pipelines and AI agents, plus the web and mobile apps on top. Then I make them faster and cheaper to run.
- Now
- Independent engineer since August 2025
- Before
- Full-stack engineer at SR Analytics and iTinker
- Based in
- India, where it’s 12:00 PM right now
- Clients since going independent
- 20+
- Countries they’re based in
- 5+
- Cloud cost I cut, per month. Capacity now follows demand, and scheduled jobs replaced servers that ran around the clock. See how
From $5,000to $72/ month- 98.56% saved
The line so far.
Scroll to ride it, from today back to day one.

Since Remote, clients in 5+ countries
I work directly with founders and engineering teams. Most of it is backend work: AI agents, machine learning features, Go services and the pipelines that feed them. When a project needs the web or mobile app on top, I build that too, and I make all of it cheaper to run.
- Agentic AI
- LLM agents that take real actions, from calling APIs to querying databases, and hand off to a person when they should. Tested before launch, traced after.
- Machine learning
- Forecasting, classification and ranking models, shipped as versioned, monitored endpoints with pipelines that keep them fed.
- Go backends
- APIs generated from an OpenAPI contract, with role-based access, PostgreSQL underneath, and deploys on Docker and AWS that nobody has to babysit.
- Cost & performance
- I find the slow path and the idle spend, then design both out. Usually with automation. Rarely with more hardware.

SR Analytics
Full-stack engineer
to Pune, India
A B2B analytics platform used by many client organizations. I worked on embedded Power BI reports, ETL from 15+ third-party APIs, multi-tenant access control and the cloud underneath. Reports got faster, and the cloud bill got a lot smaller.
- Embedded report load
From 17sto 2s- Less spent on infrastructure
- 98.56%
- Faster reporting

Full-stack engineer
to Chandigarh, India
Second-hand listings are scattered across marketplaces that don’t talk to each other. I helped pull them into one live, searchable catalog with Kotlin microservices, a scraping engine, Elasticsearch and updates pushed straight to the browser.

Read the case study : iTinkerWhere it started
B.Tech in Computer Engineering
to Charotar University of Science and Technology
Four years of computer engineering. I graduated with a CGPA of 8.92 out of 10.
Where I’m most useful.
Backend is where I go deepest. Most projects start with one of these four, and plenty end up touching all of them.
AI agents & LLM features
Assistants and agents that do real work inside your product. They call your tools, read your data, stay inside guardrails, and ship with tests you can rerun every time the model changes.
Tools: Python, LangGraph, Claude & OpenAI APIs, MCP, pgvector
Machine learning in production
Models that make it out of the notebook and into your product. Feature pipelines, training jobs, versioned endpoints, and monitoring that warns you when the data starts to drift.
Tools: Python, PyTorch, scikit-learn, pandas, FastAPI
Backends that hold up
APIs with clear contracts, permissions that still hold at customer number fifty, and real-time features only where they earn their keep.
Tools: Go, Kotlin, Java, Node.js, PostgreSQL, Redis, Kafka
Cost & performance rescue
For products that work but feel slow or cost too much. I measure first, then cut. One report went from 17 seconds to 2. One cloud bill fell by 98.56%.
Tools: AWS, Azure, Docker, Kubernetes, Jenkins, Power BI
The app on top, web or mobile
When the backend needs a face, I build that as well: a web app your team works in every day, or a phone app your customers carry around. Same repository, same weekly demo, nobody new to brief.
Tools: Next.js, React, TypeScript, Flutter, Kotlin for Android, Swift for iOS
How a project runs.
Four stops, in the same order every time.
Step 1: Call
Thirty minutes on what you’re building and what’s in the way.
Step 2: Plan
Scope, architecture, milestones and cost, in writing, before any code.
Step 3: Build
Working software in your repository from week one, with a demo every week.
Step 4: Handover
Docs, tests and runbooks. Nothing is left depending on me.

Tell me what you’re building.
A few lines will do. What it does, where it’s stuck, and when you need it. I’ll come back with questions or a plan.
