About Me
I'm Alparslan Selçuk Develioğlu, a software team lead and Scrum Master with more than 10 years in fintech, mobile and enterprise software. At Lebib Yalkın I combine team leadership with hands-on architecture and development. 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. I took DonanımHaber's Android app to closed beta as its sole developer, and at Protel I built Check&Place, a tablet app for restaurant reservations and table layouts. At Peakup I moved into iOS as well and built 2 iOS and 5 Android apps. Later I left mobile for the web and went deep into the Vue.js and Quasar ecosystems, building PostgreSQL functions and Node.js services on the backend too. Lately my focus is running AI in production: I built all of the AI integrations in MevUyum, an AI-assisted regulatory compliance platform that launched in September 2026. It recommends the legislation a company can follow from its manager's questionnaire answers, matches new Official Gazette publications to the companies they concern, and classifies regulatory changes by significance before notifying them. Before that, I built a RAG prototype for legal documents that cites its sources and says "I don't know" instead of making something up when the documents have no answer.
On the high-traffic fintech side, at ING Türkiye I built the core structure of ING Mobil's ground-up rebuild across 22 domain modules, and at Mobven I built the modular Android library used by ZiraatPay and other wallet apps. That work 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. Through code reviews, mentoring and weekly trainings, our hotfixes dropped from about two a week to about one every two weeks, roughly 75% fewer.
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. An example: in Mevbank Neo, instead of sending 227 large legal documents of up to 11.5 million characters to the browser, I opened them inside the app with virtual chunking, with article navigation, search and revision comparison still working.

MevUyum
liveLebib Yalkın · Team lead · 2026
An AI-assisted regulatory compliance platform launched in September 2026.

Mevbank Neo
liveLebib Yalkın · Team lead · 2024
A digital legislation app that tracks the latest regulatory changes, amended documents and the Official Gazette index. I lead its development and delivery. With virtual chunking in the mobile WebView, I made 227 large legal documents of up to 11.5 million characters open inside the app.
ZiraatPay Wallet Library
liveMobven · 2023 - 2024

Legal Archive Assistant (RAG)
alphaLebib Yalkın · Team lead · 2024
The prototype that started the team’s AI work: a document-grounded RAG assistant for legal documents. It answers only from source documents and shows its sources; when the documents do not cover the question it says "I couldn’t find this" instead of inventing an answer. I compared cloud and local models on the same retrieved passages.
Editor CMS

The publishing CMS I designed and built: approval workflows, document search and a PDF-to-structured-content pipeline.
ING Mobil

// Beyond the Code
Ultratrail running and powerlifting are not just sports for me; they are a way of life. I finished the Cappadocia Ultra-Trail. 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.
