Here's how

How I Work

Most consultants give you a strategy deck. Most engineers give you code without context. I do both — I understand your business problem, architect a solution, and build it myself. From cloud infrastructure to ML pipelines to the AI layer on top, I work across the full stack so nothing gets lost in translation.

End-to-End Systems Thinking

I don't just build features — I design systems. Whether it's a data pipeline, a microservices architecture, or an AI workflow, I think about how the pieces fit together, how they scale, and how they fail gracefully.

Working Software, Fast

No 6-week discovery phases. Tell me your problem, and I'll show you a working solution — often within 48 hours. You'll see results before you commit.

Built for You to Own

I don't create dependency. You'll understand how it works, how to maintain it, and how to extend it. My goal is to make myself unnecessary — or to stick around because you want me to.

Let's Be Honest About Fit

I work with two types of clients: startups that need technical depth, and small businesses that need working solutions.

For Startups & Growing Companies

We're a fit if you:

  • Need technical leadership without a full-time CTO hire
  • Want to add AI to your product and have it actually work
  • Are building something and need an engineer who sees the big picture
  • Value working software over strategy decks

For Small Business Owners

We're a fit if you:

  • Have workflow headaches you wish would just disappear
  • Want AI to work for you without learning how it works
  • Are tired of hearing about AI but not seeing results
  • Want to own your systems, not depend on a consultant forever

We're NOT the right fit if you:

  • Just need a basic ChatGPT account set up
  • Want to completely replace people with AI
  • Need a dev shop to throw bodies at a project
  • Are looking for magic with no process changes

What I Do

I offer the technical depth of a senior engineer with the strategic perspective of a CTO. Whether you're a startup scaling fast or a small business owner looking to work smarter, here's how we can work together:

AI & Machine Learning Engineering

From proof-of-concept to production. I design and build ML systems that actually work — RAG pipelines, fine-tuned models, agentic workflows, and the infrastructure to support them. Not just prompts and API calls, but real engineering.

Custom ML pipelines & model deploymentRAG systems & knowledge retrievalAI workflow automationGuardrails, monitoring & evaluation

Software Engineering & Architecture

I write production code. Backend systems, APIs, data pipelines, cloud infrastructure — I've built and shipped software at Adobe, IBM, AMD, and LinkedIn. When you need something built right, I build it.

Backend development & API designCloud infrastructure (DigitalOcean, AWS, GCP)Data engineering & ETL pipelinesSystem design & technical architecture

Fractional CTO / Technical Leadership

Need senior technical leadership without the full-time hire? I work with startups and growing companies as a fractional CTO — setting technical direction, making build-vs-buy decisions, leading engineering teams, and getting my hands dirty when needed.

Technical Cofounder (Selective)

For the right opportunity, I partner with non-technical founders as a technical cofounder. I bring the engineering, you bring the vision. Let's talk if you're building something meaningful.

AI Isn't Replacing You — It's Recruiting You.

You don't need to understand how AI works. You just need it to work for you. I build AI-powered systems that save you time, organize your chaos, and let you focus on what you do best — running your business. No jargon. No complexity. Just tools that make your life easier, delivered fast.

What this looks like in practice

A few stories from teams that recruited AI — and won.

Capacity Planning Model

The situation

A team at LinkedIn faced a 9-figure hardware allocation problem in their proprietary data centers, manually forecasting capacity with spreadsheets every quarter.

What I did

I built them a model that reasons over their historical data and constraints — so they could ask questions in plain English instead of wrestling with formulas.

The result

13.4% improvement over spreadsheet heuristic in predicting hardware provisioning needs, resulting in substantial cost savings.

improvement in accuracy

Research Acceleration

The situation

ML workloads at AMD were hitting a wall — too slow, too expensive, too power-hungry.

What I did

I designed a compute strategy that paired the right models with the right hardware, including some analog AI tricks most teams don't know exist.

The result

3–5x faster runs. Lower power bills. Same accuracy.

Knowledge Retrieval System

The situation

Critical know-how at TechnicallyFit was scattered across wikis, Slack threads, and people's heads.

What I did

I deployed a RAG system over their internal docs — so anyone could search and get real answers, not just links.

The result

New hires ramped 40% faster. Less time reinventing the wheel.

How We Work Together

From problem to production in days, not months.

01

Discovery & Architecture

We dive deep into your technical challenges. You get detailed architecture diagrams, tech stack recommendations, and a clear implementation roadmap.

02

Strategy & Planning

We refine the approach together — priorities, timelines, resources. You know exactly what's being built and why.

03

Build & Deploy

I build your production systems. Real infrastructure, real code, real results you can measure and scale.

04

Handoff & Training

You take ownership. I provide documentation, runbooks, and training until your team can maintain and extend it independently.

Darian Nwankwo

Hey, I'm Darian.

I'm a software engineer, ML engineer, and systems architect — not just an AI consultant. I've spent my career building production systems at Adobe, IBM, AMD, and LinkedIn. I hold a patent in AI, and I'm finishing my PhD at Cornell. But what I actually do is build things that work.

Most people in AI either give you high-level advice or write code without understanding your business. I sit in the middle. I can whiteboard your system architecture, write the code myself, deploy it to production, and explain to your investors why it matters.

And if you're a small business owner who just wants AI to make your life easier? I speak that language too. No jargon, no complexity — just working systems you can use tomorrow.

  • Software engineer with AI/ML focus since 2015
  • Built production systems at Adobe, IBM, AMD, LinkedIn
  • PhD Candidate at Cornell, patent holder in AI
  • I write code. I ship products. I lead teams.

What people are saying

From folks who've been through it.

Consulting with Darian using the various AI tools to leverage efficiency and organization was a force multiplier for me. The systematic approach of structured and unstructured information as it relates to how I index my own information was a game changer for me.
