I’m Tabari Brannon. I build production systems.
Data scientist, AI engineer, and software developer with 10+ years of building things that actually run in production. Not a consultancy. Not an agency. One person who does the work.
From freelance developer to data scientist.
I started 521 Solutions in 2008 as a freelance web developer, building websites and small applications for local businesses and nonprofits. That work taught me how to listen to what a business actually needs versus what they think they need.
In 2015, I founded Mesh Cowork, a coworking space in Bakersfield, CA. I built all the technical infrastructure myself: a custom ERP system for financial management and member lifecycle tracking, automation workflows connecting Twilio, Mailchimp, Airtable, and HubSpot, payment integrations with Square, and a BI platform with Tableau dashboards. I grew it to 88 members and $209K in annual revenue. I still own it today.
Building Mesh taught me more than any course could. Running the technology stack for a real business with real revenue showed me what it actually means to ship production systems that need to work every day.
I went back to school and earned my MS in Data Science from Eastern University in 2023. My capstone was a production-ready RAG chatbot for operational analytics, using natural language querying across 5 business domains with hyperparameter-tuned ML models hitting 94.8% accuracy.
I also hold an MDiv from Andrews University and a BA from Oakwood University. The divinity degree is unusual for an engineer, but it gave me something most technical people lack: the ability to communicate complex ideas clearly and think carefully about how technology affects people.
Today, I work as a data scientist building ML models, automated data pipelines, and MLOps systems in the agricultural industry. On the side, I take on select freelance projects through 521 Solutions for businesses that need someone technical, senior, and hands-on.
What I bring to the table.
Not a list of buzzwords. Actual capabilities demonstrated in production.
Full-Stack Building
I don’t hand off to junior developers. I architect, write, test, deploy, and maintain the systems myself. From database design to API development to deployment pipelines.
Business Understanding
I’ve run a business. I know what it’s like to make payroll, manage members, and watch dashboards that matter. I build tools that solve real operational problems, not science projects.
End-to-End Delivery
From understanding your problem to deploying the solution to handing it off with documentation. No project managers. No communication overhead. You talk to the person who builds it.

Want to work together?
I take on a limited number of projects at a time so I can give each one real attention. If you have a problem that needs a technical builder, let’s talk.
