Python Backend Developer & Automation Specialist

I am an IT professional with over 4 years of corporate experience in the banking sector, specifically at BBVA, where I have transformed complex manual processes into automated and efficient solutions. I specialize in backend application development using Python, SQL, and VBA, with a strong analytical ability to handle large volumes of financial data. Currently, I am focused on creating asynchronous systems, integrating third-party APIs (Finance/Messaging), and AI-assisted software engineering to optimize deployment cycles.

I am proactive, adaptable, and hold an active work permit in Spain. My work involves developing automated systems and backend architectures supported by AI tools to accelerate code production. I have developed algorithmic bots, including a “Dual Core” trading engine in Python that connects to Binance Futures and Polymarket APIs to execute real-time orders based on mathematical calculations such as RSI and EMA using Pandas.

Additionally, I implement lightweight web servers with Flask to inject real-time financial data into HTML/CSS dashboards. I integrate Telegram APIs for automated channel management and market report delivery. I utilize threading and asyncio to maintain concurrent market monitoring processes and web servers running in parallel without interruption.

My programming skills include advanced Python, VBA, and SQL. I am experienced with frameworks and libraries such as Flask, Pandas, Telegram Bot API, Requests, Asyncio, and Threading. I design REST API integrations, asynchronous architectures, and advanced prompt engineering for AI-assisted development. I also handle massive data processing in CSV, JSON, and Excel formats, and use Git/GitHub for version control, functional analysis, and QA testing.

I have a high capacity for autonomous learning and technological adaptation. I have been responsible for the full development cycle of internal applications for the Finance and Accounting area of the bank, including requirements gathering with stakeholders and programming comprehensive solutions from scratch to automate calculations, summations, and accounting validations. I have advanced VBA programming skills to ingest, process, and consolidate large corporate data files, and I integrate and query SQL databases to feed automatic report models in Excel. I also design functional and accessible internal UI/UX interfaces to facilitate tool adoption by non-technical users.
