Building things that think, feel, and ship.

I'm Subesh Bhandari — a software engineer from Nepal. By day I build a cloud security platform on AWS; the rest of the time I build AI agents with Claude, ship frontends that feel alive, and write about all of it here.

Automating your day with Claude on WhatsApp

Automating your day with Claude on WhatsApp

Connect Claude to your Gmail, Google Calendar and Google Tasks, and talk to it on WhatsApp. It sorts your inbox, flags calendar clashes, and plans the week's meals, and it asks you before it sends or changes anything. Runs on Amazon Bedrock and AWS Lambda for about $35 a month.

Deploying a Laravel application on AWS with ECS Fargate

A Laravel app is four processes, not one. This is the full deployment on ECS Fargate, with the web tier, the queue worker, the scheduler and the migration step, plus the measured cost of getting the Octane configuration subtly wrong.

Tenant isolation on AWS for a multi-tenant SaaS

Filtering by tenant_id in application code is one line, in hundreds of places, and every one is load-bearing. This is how to move the boundary into IAM session tags and PostgreSQL row-level security, with a suite that deploys to AWS and tries to break every mechanism.

Three things I think about most days.

01

AI & agents

Autonomous agents with Claude and Bedrock — tool use, MCP, planning, and orchestration. Author of Agenite, a type-safe TypeScript agent framework.

02

Cloud on AWS

Serverless and container architectures: Lambda, ECS Fargate, multi-tenant SaaS isolation, and the security posture to match. It is my day job.

03

Frontend & product

Type-safe, performant, accessible interfaces in Next.js and React — token-driven design systems, motion with restraint, Lighthouse-verified.
