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 engineer who ships.
The name comes from a story.
It’s from the Parable of the Talents — Matthew 25:14–30. Three servants are each given an amount of talents (money, in the original meaning, but the modern reading lands too): five, two, and one.
The first two multiply what they’re given. The third buries his.
I was given a mix of unusual talents — engineering, data science, business operations, and divinity training. I’m not interested in burying any of them. 521 Solutions is where I spend them, helping small businesses multiply theirs.
That’s the whole point of the company. Not AI strategy. Not digital transformation. Just: give me your hard thing, and I’ll build the system that multiplies what your business can do.
From freelance developer to data scientist to running a business.
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, real customers, real payroll — showed me what it actually means to ship production systems that need to work every day.
In 2023, I went back to school and earned my MS in Data Science from Eastern University. My capstone was a production RAG chatbot for operational analytics, hyperparameter-tuned ML models hitting 94.8% accuracy across 5 business domains.
I also hold an MDiv from Andrews University and a BA from Oakwood University. That combination is the point, not a contradiction. The Parable of the Talents — which 521 is named after — is the same story playing out in any small business: you’ve been given resources, and you can either multiply them or bury them. Engineering is how I help my clients multiply theirs. The divinity training is why I think about it that way.
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.
What working with me feels like.
No project managers. No discovery pods. You talk to the person who builds it.
You’ll talk to me directly.
No project manager. No discovery pod. No account executive. You email me, I email you back. When something needs a decision, we get on a call.
I’ll tell you when something is a bad idea.
The whole point of hiring a senior engineer is to get honest answers. If your project doesn’t need AI, I’ll tell you. If a SaaS tool would do the job for $50/month, I’ll tell you that too. I’d rather lose a project than build the wrong thing.
I won’t pad timelines or invent scope.
You’ll get a fixed quote with a realistic timeline. If I run into something harder than expected, I’ll tell you before it becomes a surprise. If the project can be smaller, I’ll tell you that, too.
You own everything when we’re done.
The code, the documentation, the deployment infrastructure, the training. No proprietary lock-in. If you want to switch developers later, you can. (Most people don’t.)
