Dear Hiring Team ,

As a Senior Data Engineer with over 15 years of experience in data-driven transformation and scalable systems. With my deep technical expertise in building complex data pipelines and my hands-on experience developing LLM-driven solutions using OpenAI, I am eager to help building the intelligent workflows that are transforming Contech.

In my current and previous roles, I have specialized in aligning technical data solutions with strategic business goals—a skill that is critical for a startup scaling its AI capabilities. My relevant qualifications include:

AI & LLM Integration: I have practical experience working with OpenAI and large language models (LLMs) to automate complex data tasks. I am skilled at bridging the gap between raw data extraction and AI-driven insights, which directly supports company's goal of moving from manual paperwork to intelligent automation.

Advanced Data Orchestration & Pipelines: At B2BROKER and Hyperio Software, I built and maintained layered Data Warehouses using Airflow, dbt, and PostgreSQL. I have developed Python-based DAGs to automate data extraction from disparate sources, which is essential for company's need to process structured and unstructured data like BI technical drawings.

Complex Modeling & Big Data: My background includes designing star and snowflake schemas for analytical workloads and using PySpark for large-scale data processing. I thrive on engineering logic for complex financial and operational scenarios, ensuring data integrity and high performance.

Collaborative team player: Beyond my technical skills, I bring a proactive mindset. I have mentored junior developers and worked closely with cross-functional teams to translate complex business requirements into technical reality.

I am particularly excited about the prospect of contributing to your "Smart Matchmaking" engine and helping to scale your platform across new global markets.

Thank you for your time and consideration. I am looking forward to the opportunity to discuss how my background in analytics engineering and AI can support company’s continued innovation.

Sincerely,

Anca Loizides
