I run my whole dev workflow from my phone
Claude Code in a tmux session on a VPS with no public ports. Three private ways in from a phone.
Result I close the laptop and pick up the same running session on my phone, with no open port anywhere.

Engineer turned
indie founder.
I build software, systems, and automation that solve real problems.
Six years building systems across hardware and software. Now building my own, in full-stack, AI / agents, and automation.
01 Products
In the works
Products are coming.
Products in full-stack, AI / agents, and automation are on the way. The case studies below are the systems they're growing out of.

02 Skills & stack
From firmware to full-stack to agents. Six years of systems engineering, now pointed at products.
01
Full-stack apps & systems
End-to-end products, vanilla or framework, zero-dependency Node servers, REST/JSON APIs.
02
AI / agentic engineering
Claude Agent SDK, MCP & skills, prompt and context engineering, self-hosted agents.
03
Workflow automation
n8n orchestration, agent pipelines, glue that runs unattended.
04
Self-hosted infra / DevOps
Dockerized, Cloudflare-fronted, on an OCI VPS, with a Tailscale mesh and backups.
05
Low-level & systems
Firmware, device drivers, embedded, RISC-V, networking, HW-SW co-design (6 yrs at Cisco & Morphing Machines).

03 Case studies
The systems that run my whole operation. Two of them are written up as public guides, so every claim has a file behind it.
My Obsidian second brain, on every device
One vault synced peer-to-peer with no middleman, snapshotted hourly to encrypted storage, and writable by my agents.
Result Notes that survive a lost phone, a bad delete, and a dead server. I have run the restore drill.
This site, a zero-dependency Node server
Vanilla HTML/CSS/JS, no build step, behind Cloudflare, doing real work.
Result A self-hosted site I extend at will, with no build step and no dependencies to rot.
A self-hosted AI agent that runs my second brain
A model bridged to Telegram by a user service on the VPS, with filesystem access to my notes and my repos.
A WhatsApp AI bot built with n8n
Two containers on a private bridge network, reaching each other by name and the internet not at all.
04 Work with me
Three ways we can work together.
Consulting
Systems, architecture, embedded / networking / full-stack, automation, AI / agents.

Tejas Kalpande
I'm an engineer who set out to build independently. I did my MTech in Electronic Systems Design (DESE, formerly CEDT) at IISc Bangalore, then spent six years at Cisco and Morphing Machines working across the stack: C, C++, Python, Go, networking, embedded software, and hardware-software co-design. Now I build products and systems in full-stack, AI / agents, and automation, and write about the journey from first principles.
