Resume

Hi, I'm Shoharab, a senior full-stack engineer.

I build the systems 1,100+ repair businesses run their day on.

Five years in production, promoted twice in four. I own the RepairCMS architecture, from the tenant guard that keeps every shop's data its own to the billing pipeline shops say saves them 20+ hours a month.

What I own today

Four tools that never agreed became one platform.

I architect RepairCMS as a senior engineer at Candy Melon in Austria. 1,100+ repair businesses in nine markets run their day on it, with one set of numbers each.

RepairCMS · Candy Melon Software · 2025 to now

1,100+ repair businesses run their day on one platform

The problem

Stock, sales, intake and accounts lived in four tools that never agreed, and on a shared platform one bad query could expose another shop's data.

What I did

Joined as an engineer, promoted to senior. I own the architecture and built the billing pipeline and the tenant-scoping rules.

The key decision

Scope every query to the shop through one shared helper, and prove it with tenant-scope tests.

What it cost

More work per module, accepted so each customer's data stays their own.

No reported cross-tenant data incident since launch; the busiest API endpoints about 35% faster (internal measurement).

How I work

Problem first. Proof last.

Every important change gets a short written record before it ships. This is a real one from RepairCMS, tagged with the habit behind each part.

Decision record · Tenant scoping in every service

RepairCMS · accepted
The cost
1,100+ businesses share one platform. One query that forgets its filter shows a shop someone else's customers.1
How shops work
Every screen a shop uses touches its own customers, stock and money, many times a day.2
Decision
Every query filters by the shop, resolved from the user by one shared helper. Looking up tenant data by id alone is not allowed.3
The price
It is a rule, not a guarantee: a forgotten filter returns every shop's data, so it has to be held by tests and review.3
Held by
A written rule in the repo, tenant-scope regression tests and code review, with older modules being brought up to the same rule. No reported cross-tenant data incident since launch.4

Everyday tools TypeScript, React, Next.js, Node.js, NestJS, MongoDB, AWS (EC2, S3, SES), Stripe, Socket.IO, OpenAI API, GitHub Actions, Jest
