About
I build software across
backend, Android, and AI.
I am a 4th-year Electrical and Electronics Engineering student at Bülent Ecevit University. I started programming in high school with C#, and over time I worked with Python, backend development, Android development with Kotlin, and AI-based systems.
During university, I focused especially on backend architecture, API development, data flow, mobile application logic, and building software around real problems. While developing Android projects with Kotlin, I also improved myself in Python-based AI, automation, RAG, and LLM-powered systems.
Today, I position myself as a developer who can think across backend, Android, and AI instead of being limited to only one area. In a project, I care not only about the interface, but also where the data comes from, how the API works, how the mobile experience connects, and how AI can be integrated safely into the system.
My goal is not to build things that only look impressive. I aim to build understandable, sustainable, and actually usable software products.
Instead of keeping my projects only in a local environment, I have also gained practical experience deploying them with AWS EC2, Linux servers, Nginx, domain/DNS configuration, and production deployment workflows.
Alongside my technical work, I am also building Relaynexa, an AI automation initiative focused on helping e-commerce brands manage customer communication more efficiently through WhatsApp-based support flows.
Backend Development
I work on APIs, data flow, databases, and system logic.
Android / Kotlin
I have experience building mobile applications and user flows with Kotlin.
AI & Automation
I integrate Python, RAG, LLMs, and automation systems with backend structures.
Deployment & Cloud
I have experience deploying projects with AWS EC2, Linux servers, Nginx, and domain configuration.
Product-Oriented Mindset
I care not only about code, but also about the real problem and usable product.
Relaynexa
Building an AI product
for e-commerce support.
Relaynexa is an AI automation initiative I'm building to help e-commerce brands handle customer communication without growing their support team.
Most e-commerce brands face the same problem: customer support is repetitive, volume-heavy, and eats into the team's time. Relaynexa is my answer to that — a WhatsApp-first AI platform that handles order tracking, shipping questions, returns, and product inquiries automatically.

Process
How I work
Here's roughly how a project goes:
01
I start by understanding the problem
I don't write code until I know what's actually being solved. A lot of bad projects start with skipping this.
02
I plan the architecture
Data models, API contracts, integrations — I think this through before building. It saves a lot of painful backtracking later.
03
I build the backend and database
FastAPI, PostgreSQL, auth, business logic — tested and structured to be extended without rewriting.
04
I add AI or automation where it makes sense
RAG pipelines, chatbots, function calling — only where they actually help, not just because it's cool.
05
I build the interface
React frontends and admin dashboards made for the actual user, not a generic template.
06
I test it properly and ship
Real scenarios, edge cases, load testing — then small improvements based on real behavior.
Why me
A few things I
do differently.
I've seen projects fail not because of bad code, but because the wrong thing got built. I try really hard not to do that.
I understand first, build second
I need to know what's actually being solved before I write anything. Code that doesn't address the real problem isn't worth shipping.
Working in practice, not just in theory
I've seen systems that looked great in demos but fell apart with real users. I think about edge cases and reliability from the start.
I can handle the whole thing myself
Backend, AI, frontend, mobile — I can design and build all of it. No handoffs, no gaps, no 'that's not my part.'
I build things meant to last
Clean structure, proper data models, documented APIs. What I build can be maintained, extended, and handed off without starting from scratch.
