Built to work.
Made to last.

Production platforms, commerce, and applied AI. The work, the decisions, and what shipped.

In focus / 01

HisabKarLay brings sales, inventory, and live payments into a shared Laravel platform, with each merchant’s data kept separate.

Backend architecture & integrations
The challenge
Scale the product. Keep every tenant isolated.
Read the case study
Inside the systemArchitecture overview

Laravel middleware

  1. Merchant request
  2. Tenant context
  3. Scoped records

Shared platform. Separate businesses.

Middleware resolves the merchant on each request, then scopes inventory, invoices, and users to that business.

Why it matters

A merchant can join without a separate application install.

A simplified view of the implementation. Read the case study for context.

Recent focus: Ollama local models for cost-efficient bots, JazzCash payment rails, FBR tax automation, and product work like InterviewIQ — a Laravel + Next.js interview-prep platform with pluggable AI.

03

AI & automation

Ollama local LLMs, WhatsApp CRM agents, pluggable OpenAI-compatible drivers with heuristic fallback, n8n workflows, resume/answer evaluation pipelines.

04

Frontend & commerce

Next.js, React + Vite, TypeScript, Tailwind, custom e-commerce (catalog → checkout), Shopify Liquid and WordPress.

05

DevOps & delivery

Nginx, Linux/PHP-FPM, Docker Compose, Git, GitHub Actions CI/CD, Vercel, Cloudflare Pages / Wrangler, production debugging and deploys.
