I'm Harun Erkam Balı. I build and operate software systems end-to-end — bringing backend engineering, infrastructure and R&D together.

Good software doesn't stop at the API. It needs thoughtful data models, a usable interface and infrastructure you can depend on.
I am a backend-focused engineer with 3+ years of experience designing, building, deploying and operating production systems. I develop C#/.NET APIs and web applications with ASP.NET Core and Entity Framework Core, alongside Django, FastAPI and Go services. My work spans authentication, payments, invoices, automation and external integrations, using MSSQL and PostgreSQL across Linux and Windows Server environments.
I'm drawn to R&D projects where performance, reliability and emerging technologies come together to solve practical problems.
B.Sc. in Management Information Systems
Necmettin Erbakan University · 2019–2023From interactive applications to production systems and applied AI.
Developing systems where backend engineering, infrastructure, real-time communication and applied AI meet. Developing C#/.NET APIs and web applications with ASP.NET Core, Entity Framework Core and MSSQL, alongside Django, FastAPI and Go services. Working across Linux and Windows Server environments with Docker and Kubernetes (k8s), and integrating AI/TTS and streaming pipelines.
Built production applications, REST APIs and internal services. Operated Docker and Kubernetes (k8s) workloads, Nginx, PgBouncer and CI/CD; improved database performance, caching, observability and reliability.
Developed authentication systems, automation tools and third-party integrations. Designed relational data models and optimized PostgreSQL queries and Redis-backed workflows.
Built an interactive educational application with Unity and C#. Worked on reusable components, UI flows, debugging, testing and performance.
Built Python and Node.js prototypes for AI experiments, including reinforcement learning. Worked with Docker, Linux, AWS EC2, automation and data-processing workflows.
Tools I use across software, operations and research.
Selected software, hardware and R&D work. Private repositories are not linked; architecture overviews or selected code excerpts can be shared when appropriate.
A self-hosted software engineering team with dependency-aware planning, real project validation, independent QA and review, and a human approval boundary. Early engineering release.
A .NET API and background-worker platform for NSP business data, with authentication, client and dealer workflows, CRM operations and reporting backed by MSSQL.
Wireless headphone development combining Wi-Fi and Bluetooth connectivity.
Reverse engineering of an audiogram device to understand its operation and integration requirements.
Development of a listening test and its supporting application workflow.
CRM development for the NSP platform, covering client records and operational workflows.
Audio streaming development for the NSP platform.
An independently developed FinTech platform, connecting backend services, data and a React interface.
Low-latency communication between application backends and TTS workers, with streaming, retries, timeouts and worker orchestration.
Inventory, cargo and device tracking workflows, implemented with Firebase and MSSQL variants.
Cognitive-performance exercises, user progress tracking and education workflows in a web application.
A reading application extended and optimized for education users.
An interactive educational application designed for advanced learners.
