TAHA KEREM ERİŞ

I'm a computer engineer. I've built web systems with .NET, done internships on FPGAs and PLCs, and I spend my free time on iOS reverse engineering. I graduated in June 2026 and I'm looking for a job.

Propeller calculator

My family's company, Eriş Pervane, makes ship propellers, and I built its calculation site, pervanehesabi.com. The geometry and numbers for this propeller come from the Wageningen B-series. The calculation runs in your browser and it's drawn with WebGL2. Try changing the values below.

Blades

Polynomials and geometry: Oosterveld and van Oossanen, 1975. Rn = 2×10⁶, sea water. For demonstration only. To choose a propeller for your boat: pervanehesabi.com.

From interface to hardware

A summary of what I've done at each layer.

Product and interface

I designed and shipped pervanehesabi.com and erispervane.com from scratch. pervanehesabi.com is a four-language form that calculates a propeller from a boat's data.

ASP.NET Core Razor Pages, HTML, Swift

Backend

I built the server side of those sites and the company's internal ERP modules. I worked on fintech projects at Payco, and built the diabetes app's back end with Node.js microservices.

.NET 9, C#, ASP.NET, Node.js

Data

I designed database schemas for the ERP and stored high-frequency health data without gaps. With my team, I trained a detection model on a 2.3-million-row attack dataset.

PostgreSQL, MySQL, MongoDB, Python, scikit-learn

Infrastructure

I ran Eriş Pervane's network and IT systems for six years and set up Docker-based local Linux servers (NAS) for its workflows. At home, my own services run on a low-power Linux box.

Docker, Linux, DietPi, network administration

Operating system

I've been taking iOS apart for years: jailbreak methods, tweak development, app reverse engineering and entry-level kernel vulnerability research. I've also helped people with these topics on forums.

iOS, Swift, closed API analysis

Embedded and automation

At A Grup I did R&D on microcontrollers and FPGAs, and worked on motor drivers, PLC and servo integration and motion control. I learned PLC programming at Batek Makine.

C, FPGA, Siemens SIMATIC, TIA Portal, Factory I/O

Hardware

On FB-CPU, we designed a processor at RTL level with state machines. As a hobby, I do RLC circuit analysis and build audio systems with components I choose myself.

Verilog, circuit analysis, DSP

AII attended deep learning bootcamps and used machine learning in my projects: predicting risk from a glucose sensor, classifying city sounds, detecting attacks in network traffic. I work with Python and AI agents.

Experience

  1. Kocaeli

    Eriş PervaneIT and software specialist

    I ran the company's digital transformation, network and IT systems end to end. I moved a 25-year-old ship propeller calculation project to a modern architecture with .NET 9 and Razor Pages. I also built ERP modules, PostgreSQL and MySQL schemas and system integrations for internal processes.

  2. Istanbul

    A Grup ŞirketlerEmbedded systems intern

    I did hands-on R&D on microcontrollers and FPGAs. I contributed to industrial motor drivers, PLC and servo integration and motion control, and worked on integrating robotic hardware with low-level software.

  3. Istanbul

    Payco Electronic Money and Payment ServicesSoftware intern

    I worked on enterprise fintech projects with C#, .NET and ASP.NET. I gained experience containerising and deploying microservices with Docker, improved content management systems and followed Agile processes in JIRA.

  4. Kocaeli

    Batek MakineAutomation intern

    I learned basic PLC programming with Siemens SIMATIC and TIA Portal. I modelled and tested industrial workflows in Factory I/O, and studied RPA solutions and production line control on site.

Projects

Graduation project, since 2025

A native iOS app for AI-assisted diabetes management

  • Reads live data from a continuous glucose monitor (CGM) through APIs I reverse engineered.
  • Studies past trends and predicts hypoglycaemia and hyperglycaemia risk ahead of time.
  • Runs OpenAPS, the open-source artificial pancreas algorithm, inside the app. A carb counting module lays the groundwork for insulin dose calculation.
  • Keeps critical health data flowing in the background with Node.js microservices and MongoDB.

Portrait of Taha Kerem Eriş

I like working on my car in the garage: I've fitted a strut brace and tried performance software.

My desk has a DAC and an amp, I modify passive speakers and play with DSP. I build my own electronics projects too.
