Tushar B.
About this gig
Your AI agent works in the demo. In production it loops, forgets, or costs too much. I build the version that stays up.
I'm Tushar, CTO and Full Stack AI Engineer. My own AI automation runs every morning: agents research, write and publish content across two products with 30,000 visits a month, with one approval from me. My code is merged at Expensify (Nasdaq, 10M+ users), a Featured Client here.
WHAT I BUILD
- AI agents with tool use, memory and guardrails: Claude, OpenAI, Python, LangChain
- n8n or Zapier AI automation workflows, webhooks and API integration
- AI chatbots on WhatsApp, Telegram and Slack
- RAG over your docs, with citations
- Fix n8n or Zapier workflows and agents that break
APPS I CONNECT
Google: Sheets, Gmail, Drive, Calendar
CRM and notes: HubSpot, Airtable, Notion
Payments: Stripe
Messaging: WhatsApp, Telegram, Slack, email
And any tool with an API or a webhook.
WHY WORK WITH ME
- Retries, logging, cost caps and alerts built in
- Workflows and code on your accounts, you own them
- Fixed price, daily updates, reply within 1 hour
Send your process or the failing agent. Fixed quote in 1 hour.

Zero to 30,000 visits a month on pure automation: an agent researches, writes and publishes every morning, and I approve it once. That's my own product, built end to end.
My code is merged at Expensify, a Featured Client here. Primary engineer on a public post-quantum protocol, 990+ commits. CTO, 8 years building software.
I build SaaS MVPs and AI web apps in Next.js, React, Node and PostgreSQL, AI agents and automations that run daily, and I rescue apps built fast in Lovable, Bolt or Replit. Auth, payments, admin, RAG chatbot, deployed, source in your repo.

FAQ
We built a PoC that hallucinates or loops. Can you fix it?
Yes. Send the repo or the n8n export. I review it, list the failure points, quote a fixed price, and rebuild what is broken: retrieval, tool calls, state, retries, cost.
What if I just need a simple automation?
Then Basic is enough: one automation or one agent, one integration, delivered in 3 days. I use n8n where it fits and code where it matters.
Do I need technical knowledge to use it?
No. You get a handover doc, a short video walkthrough, and it runs on your own accounts. You can change prompts and schedules without me.
Which tools and models do you work with?
Claude, OpenAI, Gemini and open models via OpenRouter; Python, TypeScript, LangChain, CrewAI, n8n; Google Sheets, Slack, Gmail, Notion, HubSpot, Airtable, Stripe, WhatsApp, Telegram, Postgres, any REST API.
Can you automate WhatsApp, SMS and email follow-ups?
Yes, on the official WhatsApp Business API, Twilio and Gmail or SendGrid. Lead capture, qualification, replies and follow-ups, with a human handoff when needed.
Who owns the code and the workflows?
You do. Everything is deployed on your accounts and delivered in your repo, with API keys in your hands. No lock-in.
What happens if something breaks after delivery?
A support window is included in every package. Every build ships with logging and alerts, so I see failures before you do.
How much does running it cost?
I set model routing and cost caps so the monthly bill is predictable. You get an estimate before I build and a usage report at handover.
Do you sign NDAs?
Yes, yours or mine, before you share anything sensitive.
Do you work with my existing developer or team?
Yes. I hand over clean code and docs, join a call with your team if needed, and stay available for questions.
