Real systems. Measured impact. Clean code.

You don't need a 45-minute pitch deck. Here is how I approach edge backends, checkout performance and full-stack architecture: the problem, the architecture decisions and the results.

Featured Case Studies

Two case studies: the systems behind this site, which you can inspect live.

Edge & Billing SazM (this site)

Edge Subscription & Checkout Engine

The billing and checkout system behind sazm.in: two payment gateways, country-based pricing and subscription webhooks, running on Cloudflare's edge. You can inspect it live on this site.

The Challenge

Visitors pay in their own currency through the payment gateway for their region. Each visitor must see only their own prices and checkout, with nothing from the other region leaking into the page.

The Architecture

A Cloudflare Worker reads the visitor's country at the edge and rewrites the page to the matching currency and gateway. Webhooks are verified (each gateway's own signature check) and processed idempotently into a D1 SQLite database.

CI/CD & Automation SazM (this site)

Task-to-Pull-Request Delivery Pipeline

The delivery pipeline SazM clients use: a task queued in the client portal becomes a pull request in the client's repository, with a staging preview link, without status meetings.

The Challenge

Clients need to review working software within 24–48 hours without pulling Git branches or running a local environment, and without status calls.

The Architecture

A Linear webhook hands the top task to a GitHub Actions workflow, where an AI coding agent drafts the change and opens a pull request. Staging previews are served at preview-[id].sazm.in, and Telegram and email alerts track each step.

How SazM ships software

Four non-negotiable principles embedded into every pull request and feature delivery.

⚡

Edge-first execution (< 20ms worldwide)

Compute runs close to your users via Cloudflare V8 isolates. No cold starts, no single-region lag, and zero unnecessary server maintenance.

🔒

Strict end-to-end TypeScript types

Strong types from SQLite schema to React components. Breaking changes are caught at compile time before code ever reaches production.

📦

Zero unnecessary dependencies

Every npm package is a liability. I build with standard Web APIs, minimal island hydration, and lightweight primitives that stay fast for years.

🛡️

Complete code ownership

Everything is committed directly to your repository. You own all intellectual property, clean documentation, and test suites with zero vendor lock-in.

1 Active Task at a Time
Requests are completed one by one in your priority order. As soon as an active task is shipped, tested, and approved, work starts immediately on your next task within our 24–48h SLA.
48h Emergency SLA
Clock starts as soon as site access details are provided. Delivered with full backup taken first, isolated staging testing, and 100% money back if not fixed.
WordPress Care Plan Scope
Weekly core and plugin updates pre-tested in staging, daily offsite encrypted backups, 24/7 uptime monitoring, and proactive security patching.
