Fırat Çelik

Senior Data Analyst, Fullstack Developer & Team Leader

I'm a Senior Data Analyst, Software Developer, and Team Leader with over 7 years of experience specializing in data analytics, mobile application development, and backend systems. My expertise includes designing scalable solutions with GoLang, Python, and PostgreSQL, optimizing business processes, and delivering predictive analytics platforms. I have a proven ability to lead cross-functional teams, automate workflows, and create user-centric applications that drive operational excellence and strategic decision-making.

Professional Background

At AgFlow S.A., I manage the data parsing process, lead the Dev team, and focus on improving data flow operations. I've pioneered the use of predictive modeling techniques and served collected data as an external API, feeding big aggregators such as Bloomberg. I've also automated data ingestion of agricultural trading symbols and references from various problematic data formats, including HTML scraping, PDF table extraction, image analysis, and email parsing.

My experience includes working with diverse teams across different cultures and backgrounds. I've also taught C# and SQL to teenagers as part of an EU-supported project in Ukraine, which strengthened my communication and problem-solving skills.

As a freelance web developer, I've created multiple client websites including narcis.ch, my-pwb.co.uk, and the-leadlab.com, showcasing my ability to build modern, responsive web applications with excellent user experiences.

Technical Skills

My technical toolkit includes:

  • Programming Languages: GoLang, Python, C#, SQL, JavaScript, TypeScript
  • Database Management: PostgreSQL, MSSQL, PLSQL
  • Data Analytics Tools: Tableau, Power BI, Business Intelligence
  • Backend Development: Git, Docker, Jenkins
  • API Development: RESTful APIs, Microservices Architecture
  • Search and Indexing: Elasticsearch
  • Frontend: React, Next.js

I'm proficient in conducting in-depth analysis of large data sets, developing machine learning models for predictive analytics, and automating data ingestion processes from various formats. I excel in creating scalable backend systems, designing user-friendly interfaces, and establishing external API services for data distribution.

Approach

I believe in a pragmatic approach to problem-solving, focusing on delivering solutions that are not only technically sound but also address real user needs. I'm constantly learning and adapting to new technologies and methodologies.
