Software & Data Engineering

Created: 2026-11-08  ·  Last updated: 2026-11-08  ·  Nejat Hakan

Executive Summary: Modern enterprise applications demand high-throughput data processing, memory safety, and robust data persistence. Software engineering cannot be treated as separate from the underlying systems architecture: the runtime behaviors of compiled and managed languages directly dictate database latency, cache efficiency, and machine learning throughput. This domain unifies low-level systems programming, relational database engineering, and production data science into a cohesive engineering stack.

  • Systems Programming Track

    Engineered across 5 languages: Low-level ISO C17 memory management, modern Python 3.12 asyncio, Go concurrency, Java virtual threads on OpenJDK 21, and compile-time memory safety in Rust.

  • Relational Database Engineering

    Production data architectures: PostgreSQL 17 and MariaDB 11.4 provisioning, ACID transaction guarantees, B-Tree/GIN/BRIN index internals, MVCC autovacuum tuning, and physical streaming replication.

  • Data Science & MLOps on Linux

    End-to-end analytical pipelines: POSIX CLI stream processing, NumPy AVX-512 SIMD vectorization, Pandas 2.x PyArrow backend, data leakage-free Scikit-learn pipelines, and FastAPI model serving.

Domain Pillars & Core Competencies

1. Polyglot Systems Programming

Enterprise engineering requires selecting the right language for the specific execution boundary. From bare-metal pointer arithmetic in C17 and RAII memory safety in Rust to Go's lightweight goroutines and Python's asynchronous network I/O, this pillar builds rigorous systems-level fluency.

2. High-Concurrency Database Engineering

Persistence is the anchor of system reliability. This pillar covers transactional integrity, schema normalization (1NF–BCNF), index architecture, query optimization with EXPLAIN (ANALYZE, BUFFERS), connection pooling via PgBouncer, and disaster recovery via streaming replication.

3. Production Data Science & Machine Learning

Real-world data science moves beyond isolated Jupyter notebooks into production Linux pipelines. We focus on zero-copy Arrow memory layouts, SIMD-accelerated array computing, leakage-free estimator pipelines, and robust model lifecycle management with MLflow and FastAPI microservices.
