I am Muhammet, a software engineer and a graduate of Bursa Uludağ University. For the last three and a half years I have been doing one thing over and over, in different industries: walking into a company where the real work lives in spreadsheets, paper forms and somebody’s head, and walking out with a system that runs it.

In practice that has meant ERP customisation on a packaging line, SAP integrated production tracking and OEE on a laminate factory floor, a CRM welded to a CAD/CAM product, and today an entire back office portal at Sango: HR, training, IT, DMS, QDMS, e-archive accounting, purchasing, supplier and customer portals and project management, on .NET, MSSQL and Angular with a configurable workflow engine underneath.

Outside work I build products: an outdoor social network, a travel route planner, a digital menu SaaS and a low-code studio. Same instinct, different audience. Take something people do by hand and make the software disappear behind it.

Selected Work

Sipatra

In progress / 2026

The outdoor social network for hiking, cycling, paragliding and camping.

One recorder for every sport: pace and climb on foot, speed and cadence on the bike, altitude and glide in the air. The track is written to the phone first and uploaded later, so a dead zone never costs a recording. Privacy Zones are cut out on the server before anyone sees a route, and over a hundred thousand camps, water points and viewpoints across Europe sit on the same map as the trails between them.

STI Portal

Internal / 2026

A back office platform that moved a whole company off paper.

Built from scratch at Sango on .NET, MSSQL and Angular. HR, training, IT, DMS, QDMS, e-archive accounting, purchasing, project management and the supplier and customer portals all live in one system. API, web and mobile advance in parallel, and the workflow engine underneath lets approval flows be configured instead of coded.

Service	.NET, ASP.NET Core, Workflow Engine

OGE UI

Live / 2026

A signal-based, zoneless UI component suite for Angular and React.

The components enterprise screens actually need, built the way Angular works now: signals instead of zone change detection, and virtualisation so a grid stays responsive at row counts that break most suites. Data Grid, Tree List, Pivot Grid, Select Box, inputs and buttons, shipped open-core under MIT with a commercial pivot.

Creo Studio

Live / 2025

Design an application in Studio, run it in Runtime.

A low-code and no-code system development studio. A business configures its own data models, forms and workflows in Studio; Runtime renders and executes them without a release. Built so that a process change does not have to become a sprint.

Build a travel route, then let it optimise itself.
