Résumé
Experience, education, skills and references on a single page.
I'm Berkay, a senior Computer Science student at Bilkent University. I build backend systems in Go, forecast electricity prices with machine learning, and like knowing how code travels all the way to production.
Now: day-ahead electricity price forecasting at Gain Enerji.
Before: Go microservices at Monitic and Payko, DevOps at Turkcell.
Also: research for an upcoming book on energy digitalization.
Data-driven analysis of Turkish electricity markets: building and maintaining production-level day-ahead price (PTF) forecasting models on EPİAŞ market data.
Own the full pipeline: data collection, cleaning and feature engineering from market, generation and weather signals.
Develop and evaluate gradient-boosting models whose forecasts feed day-to-day trading and planning decisions.
Provide system design support for internal data and analytics tooling.
Backend services for a remote monitoring and management (RMM) platform, built as a set of Go microservices.
Designed and shipped REST APIs with Golang and Fiber.
Used goroutines for concurrent agent and device workloads.
Worked across MongoDB, Redis and Docker in a microservice architecture.
Supported Turkcell's central DevOps team, which serves the company's ICT departments.
Worked with Jenkins, SonarQube, Git/Bitbucket, Artifactory and OpenShift.
Saw how CRM, finance, mobile and AI/ML projects plug into automated delivery pipelines.
Part of the student research team behind an upcoming book by Prof. Sinan Küfeoğlu on data-driven energy transformation.
Background research and draft material for the chapter on IoT and smart energy management.
Contributed to the AI/ML in energy chapter: real-time monitoring and control, smart-grid integration, predictive models and renewable forecasting.
RESTful CRUD APIs in Golang at an early-stage fintech startup.
Implemented nearly half of the company's CRUD endpoints.
Contributed to documentation, testing and PostgreSQL-backed development.
Career history, recommendations and the occasional post. Happy to connect.
