About

Through Aykut Bilişim Teknolojileri, I develop mobile, backend, and web products from initial requirements through release and production operation. My work combines cross-platform application development, API and data design, real-time communication, media processing, payment flows, third-party integrations, and deployment automation.

I am most effective on features that cross system boundaries: defining the backend contract, implementing the client experience, handling failure cases, testing the complete flow, and shipping a release that can be monitored and rolled back safely.

Selected work

Focused, inspectable repositories that demonstrate how I approach correctness, testing, and operational risk.

01

Laravel Wallet Ledger

A production-minded Laravel reference for server-authoritative balances, atomic wallet mutations, idempotent purchase processing, signed webhooks, refunds, and auditable ledger history. The suite covers the critical money paths with 7 automated tests and 33 assertions.

  • Laravel
  • PHP
  • PostgreSQL
  • MySQL
  • PHPUnit
02

Flutter Runtime Environments

A focused Flutter implementation for switching API and native service environments at cold start while keeping production-safe defaults. It documents persistence, Firebase boundaries, failure handling, and verification across release-style builds.

  • Flutter
  • Dart
  • Firebase
  • iOS
  • Android
03

MySQL to PostgreSQL Migration Kit

A repeatable migration rehearsal kit for moving relational workloads from MySQL to PostgreSQL. It validates schema compatibility, row counts, data fingerprints, sequence state, and rollback readiness in a Docker-based end-to-end workflow.

  • PostgreSQL
  • MySQL
  • Docker
  • Bash
  • Data Migration

Experience

2022 — Current

Software Engineering & Technical Consulting

Aykut Bilişim Teknolojileri
  • Deliver web, mobile, and custom software products as complete systems, from technical discovery and architecture through release preparation and production support.
  • Design API contracts, client behavior, data flows, integration boundaries, automated checks, and operational safeguards around the same product outcome.
  • Provide technical consulting across cloud infrastructure, data management, environment separation, diagnostics, controlled deployment, and rollback planning.

Current

Product Engineering

Yasa Group
  • Build and operate cross-platform social and live-media product flows spanning Flutter clients, Laravel APIs, real-time room state, chat, ranking, gifting, wallet, posts, reels, stories, and notifications.
  • Integrate Firebase, Firestore, ZEGOCLOUD, WebRTC, DeepAR, Socket.IO, RevenueCat, media storage, moderation, and administrative review workflows.
  • Prepare iOS and Android releases with separate staging and production environments, TestFlight and store delivery, APK/AAB pipelines, diagnostics, and controlled deployment procedures.

2026

Open-Source Reference Systems

Public Engineering Work
  • Published focused reference implementations for wallet integrity, runtime environment selection, and MySQL-to-PostgreSQL migration rehearsal.
  • Documented operational assumptions, test boundaries, failure paths, and repeatable verification steps so each repository can be evaluated independently.
  • Use small public systems to demonstrate the same engineering concerns that matter in private production work: correctness, observability, controlled change, and recovery.
