About Me
I'm Alparslan Selçuk Develioğlu — a software developer, Scrum Master, and software development team lead. I'm also a long-distance runner and a blogger.
I don't see software as just writing code. For me, it's about building systems that are sustainable, fault-tolerant, and truly owned by the team — not just systems that work.
I started my career on Android. My first serious step was an indoor navigation app I built at university, which was selected as the best graduation project. Over time I moved beyond Android into iOS, then left mobile entirely for the web — going deep into the Vue.js and Quasar ecosystems. I didn't stop there; I've also built PostgreSQL functions and Node.js services on the backend.
Working in high-traffic fintech environments like ZiraatPay and ING sharpened a clear reflex in me: learning to operate in systems where error tolerance is low. Today, as a software team lead, I carry that same approach. I'm not just someone who manages a team — I engage with the architecture, get into the code, and play an active role in code reviews. I've seen this approach meaningfully reduce error rates across teams, time and again.
Clean code, sustainable architecture, and a strong engineering culture are non-negotiables for me. I treat topics like SOLID principles, design patterns, and Git workflows not as theoretical knowledge, but as natural parts of daily production.

Legal Archive Assistant (RAG)
alphaLebib Yalkın · Team lead · 2024
The project that started the team’s AI work: a document-grounded assistant over a legal archive. It answers only from source documents and shows the source under every claim; when the archive does not cover the question it says "I couldn’t find this" instead of inventing an answer.

ING Mobil
liveING Türkiye · 2020 – 2023

Envisense
livePeakup · IoT office automation · 2019

A Git-submodule helper library I designed and built to centralize shared code across projects and remove duplication.

// Beyond the Code
Ultratrail running and powerlifting are not just sports for me; they are a way of life. Long-distance running is not only a physical activity but also where I build discipline, rhythm, and mental resilience. That mindset carries directly into how I work.
On the science fiction side, I am especially drawn to questions of time, mind, and future systems. Isaac Asimov stands out.
On the coffee side, I prefer simple rituals. A V60 is usually what carries long working sessions.
This site, devdiscipline.com, is an extension of all of this. I bring together software, ways of thinking, habits, and personal growth in one place. The goal isn't to tell polished stories — it's to share real experience, real mistakes, and real learning as they are.
// Editor's Note: The clarity of every sentence, the discipline in every idea, and the flow of the narrative in this blog are all shaped by the unique editorial touch and hard work of my wife, Nare Buse.
