Kaushalya's Agents
Generating action…Calling crm.update…Done · 3 tasks ✓
LLM-powered products end to end: chat agents on MCP, n8n automations and custom pipelines that plug straight into real business workflows.
Secure REST APIs, auth, payments and data models built on Node, Express, Prisma and MySQL, shaped around the product rather than the framework.
VPS setups, reverse proxies, SSL, PM2 and CI/CD pipelines so releases stay repeatable and downtime stays rare.
The languages, frameworks and platforms I reach for every day, from the first commit to the server it runs on.

AWSA few of the things I've designed, built and deployed recently, from a live POS SaaS used by real shops to learning platforms and AI agents.
Bila

The till keeps billing offline and syncs when the connection returns.
Zero hardware
Runs on any phone, tablet or laptop; no scanner or receipt printer needed.
WhatsApp receipts
Bills go straight to the customer's WhatsApp instead of paper.
Inventory, staff & outlets
Stock tracking, sales numbers and multi-staff, multi-outlet support built in.
The roles, teams and clients behind the work, most recent first.

Building and shipping production software as part of Codimite's engineering team.
Full Stack Developer
Built client websites, admin panels and internal products end to end, including the CreatXPM project management app.
BSc (Hons) in Information Technology
Undergraduate degree covering software engineering, systems and emerging tech, alongside professional work.
I turn ideas into products that ship. I take on the whole build: interfaces people enjoy, backends that hold up under load, AI features that solve real problems instead of demos, and deployments you can update without holding your breath.
Start a ProjectTypeScript from database to UI so whole classes of bugs never reach production.
GitHub Actions pipelines build, test and deploy every change the same way.
Auth, input validation, least-privilege keys and security reviews are part of the build.
Clear docs, readable code and deploy guides so your team is never locked in.
Years of shipping for clients, startups and my own products, from first sketch to production servers.

Visit Bila →Five steps, the same way every time.
I learn the business problem, the users and the constraints before writing a line of code.
Data model, API shape and interface are planned together so nothing gets bolted on later.
Typed end to end, small commits, and a working preview you can click through every few days.
Automated checks plus real-device testing on the flows that make or lose money.
CI/CD to your server with SSL, monitoring and a handover you can actually maintain.
