About Marsha

Marsha’s Biography

Marsha Castello is a Data Analyst, and a master’s graduate from the University of London. She also a certified PRINCE2 Practitioner in Project Management, a hugely transferable skill, and over the last year, Marsha has up skilled in the areas of both Software Engineering and Data.

Marsha is passionate about data as, in her own words it underpins everything we do, providing a diagnostic narrative as to why, when, where and how every phenomenon occurs. As such data intersects with all areas within tech, we can therefore employ an array of tools to sharpen data processes and techniques.

To this end she has enjoyed building proficiency in Python, SQL, Advanced Data Analysis, AI & ML, Azure, Power BI, Tableau, and Advanced Excel including Power Query. Empowered with this skillset Marsha has created AI and Machine Learning models, exploratory analysis & forecasting, web scrapping tools, and beautiful visualisations in her own time, independent of her courses developing her capacity to get to the heart of invaluable data insights.

Marsha has also successfully completed a 16-week Software Engineering bootcamp, where she has gained further proficiency in the following: Java, Git, GitHub, Test Driven Development (TDD), Software Design and Software Architecture, Databases, API’s, JavaScript, React, Linux, Command Line and Scripting, Continuous Integration and Continuous Delivery (CI/CD), Docker, Kubernetes, and Agile methodologies.

These cross-cutting skills help to take the capacities of data exploration to new lengths, and Marsha hopes to apply such transferable knowledge in building a career in the areas of further Data Analytics, Data Science/Engineering.

Marsha has enjoyed proactively leading on and collaborating on several projects to test and expand her knowledge, incorporating her learning into her current role, and sharing her knowledge and engaging with the vast number of networks, including GTA, that she feels privileged to be a part of.

Marsha remains committed to using tech for social good and lasting positive change and she has recently served as a UN Women UK delegate to the United Nations Commission on the Status of Women.  This involved learning and raising awareness about and strategising on closing gender equity gaps for women in the areas of education, safety, and access to opportunity in today’s digital and AI revolution. Gender parity is an area I feel extremely passionate about as I believe we cannot achieve a healthy and fully functioning society without the inclusion of half of the world’s population.

Marsha aims to continue be a role model in this space through mentorship, advocacy and the sharing and application of her knowledge, skills, and experience. Following on from the commission, Marsha is excited to share that her article on ‘Tech for the Empowerment of Women’, has been published by BCS, The Chartered Institute for IT.


Marsha has also been featured in the following articles:

–  Black History Month UK – Black Women in STEM

–  ExtraOrdinary Tech Stories

–  The Trendy Coder

Marsha would also like to draw attention to the excellent Dimbleby Lecture by David Harewood, on the Windrush generation as referred to in her personal story as featured in Voices in The Shadow Vol. 3

In her leisure time she enjoys Fitness bootcamps, Pilates, Kettlebell workouts, theatre, live music, art (appreciation & creation), movies and all things tech & technological innovation.

Marsha feels excited to have received multiple nominations for the We Are the City – Rising Star Awards and is extremely proud and elated to have been nominated to appear here in GTAs Black Women in Tech: The Voices in the Shadows 3, alongside so many talented and inspirational peers. She hopes we can continue to build a vibrant and supportive community and looks forward to witnessing and cheering one another’s growth and success!
