I am an Accountant, Financial Modeller, and Automation Expert for Windows & MAC (Excel & Access, Outlook, PowerPoint) primarily using VBA, SQL, Google Sheets, Slides & Docs, and Python. I have produced hundreds of automated spreadsheets, databases, and IT solutions for clients over the years since 2005. I've been a professional Excel Financial Modeller and VBA Developer since 2005, working with numerous accountants and actuaries to produce mainly VBA automation tools and integrated financial models. I have also written a number of business plans for start-ups over the years and secured funding for them. In 2009 I produced my own Excel-based financial forecasting software (FD4Cast) which allows users to quickly build dynamic integrated financial models driven by VBA, and which got ICAEW approval as an accredited software platform. Since then I have built many dynamic, customised models for the Construction, Healthcare, FMCG, Automotive, Entertainment, and Financial sectors, but also completed many varied (non-financial) automation solutions for clients where the needs have been complex. I work well under minimal supervision and I always provide excellent support for previous projects where needs may have changed and modifications required.

I've been a software developer since I left academia in 2008, working on financial software, mobile apps and customer relationship management software in a variety of languages. My recent big Upwork jobs were a PHP web service and a C++ desktop app for Windows. I believe in clean code! I can communicate technical concepts to an audience or one-to-one: I've delivered lectures, demonstrations, talks and tuition. You can find me on Stack Overflow as Tommy Herbert - current score 19,616! My pronouns are he/him, but they/them is fine too.

I'm Pablo, a Chemical Engineer and full-time Data Scientist with 9+ years of well-established professional and academic track record. I specialize in statistical and mathematical computation, machine learning research and model deployment, software development, and business consulting. I'm highly technical and extremely rigorous while maintaining a personable touch through every client interaction, and have a proven track record in the petrochemical, market research, and consulting sectors. I selectively partner with clients, prioritizing high-profile projects that align with my expertise and pristine standards. You can find me here: ◉ LinkedIn: /in/pablo-aguirre-nunez ◉ GitHub: /ajourneythroughdatascience ◉ Technical Blog: pabloagn.com How I choose my projects: ◉ I only deliver top-quality work and abstain from taking subpar requests that compromise quality for cheap solutions. ◉ I have a strict No-GenAI policy, this is a non-negotiable; I don't use it anywhere within my process since I think it's unethical and severely lowers the quality of the deliverables. ◉ I also abstain from responding to requests that undervalue the task at hand (NOTE: If a client is in need of a solution but the budget is constrained and the client acknowledges this, I will happily take the case and try to propose a viable & realistic approach in return). Below you can find an overview of the tools I frequently work with: NOTE: If a tool is listed below, it means that I am highly experienced or proficient with it. It also means that I can attest to this expertise if required. ◉ Data Science & General Purpose: ◎ Python, R, Julia, Scala ◉ Engineering: ◎ Kubernetes, Docker, Apache Airflow, Apache Spark (Scala, PySpark), Elixir, Apache Kafka, Apache Flink, AWS and Unix environments for virtual solutions. ◉ Databases: ◎ SQL (PostgreSQL, MySQL, MariaDB) and NoSQL (MongoDB, Redis). ◉ Data Visualization: ◎ PowerBI (DAX, PowerQuery M), JavaScript, Python (Matplotlib, Seaborn) and R (ggplot2). ◉ Back-end & Systems Programming: ◎ Rust, Node JS and Linux System Administration (Debian & Debian-based, Kali Linux, Oracle Enterprise) with proficiency in Bash/Zsh scripting. ◉ Prototyping: ◎ Figma and Adobe Illustrator. ◉ Documentation & Version Control: ◎ LaTeX, Markdown, Git and GitHub. ◉ Project Management: ◎ Linear, ClickUp and Asana [If I don't know something, I learn it quickly, as I've been doing every day since I transitioned to a full-time Data Scientist] I've worked in the following industries: ◉ Petrochemical ◉ Agricultural ◉ Financial ◉ Consumer and Retail ◉ Business Consulting I'm experienced with: ◉ Behavior of complex processes ◉ Mathematical modeling across diverse contexts ◉ In-depth knowledge of consumer behavior ◉ Robust data analysis and interpretation ◉ Strategic consulting in complex fields of study ◉ Cross-disciplinary collaboration I've been excelling at the following for years: ◉ Abstracting business problems into computational solutions. ◉ Building complex solutions, performing validations, executing proofs of concepts, conducting unit tests and performing deliveries in many flavors to many different types of stakeholders, including those of technical and non-technical backgrounds. ◉ Contributing to the open-source community by creating and maintaining projects and utilities. ◉ Sharing my knowledge in a clear and concise manner to people interested in the field.

A highly motivated and results-driven Computer Science with Artificial Intelligence undergraduate at King’s College London, currently in my final year and predicted a First-Class Honours. I bring professional experience in both front-end and back-end development, having worked extensively with technologies such as Microsoft Azure, Django, and API integration.. During a recent 3-month software engineering internship at an upcoming finance company, I designed and implemented three key systems: an automated survey distribution and analytics platform, a broker management/CRM system, and a company intranet. These projects enhanced business efficiency and demonstrated my ability to deliver impactful technical solutions in a fast-paced environment. At university, I successfully completed a 4-month Major Group Project developing with Django, and gained further experience in React as a Web Development Intern. In addition to my technical skills, I am an experienced tutor, having helped students excel in GCSE and A Level subjects through the MyTutor platform. I have published articles on technology and productivity for publications like "Women in Technology" and "Long. Sweet. Valuable." on Medium. Additionally, I hold certificates from JP Morgan Chase & Co.’s Software Engineering and Cognizant’s Artificial Intelligence Virtual Experience Programs. With a strong academic record (A*A*A*A in A Levels and an 81% average at university), I am eager to bring my skills to innovative projects and continue growing in the tech industry.
