Eze David Obinna

Senior Software Engineer • AI Engineer • Technology Product Builder

I build intelligent digital products and production-grade software systems across AI, fintech, SaaS, web and mobile — from architecture and engineering to deployment.

Who I Am

An End-to-End Technology Builder

I take products from idea through architecture, engineering, AI, and integrations, all the way to production infrastructure. That range — across AI, fintech, SaaS, web, and mobile — is deliberate: real products rarely fail because of one weak layer, they fail at the seams between layers, and someone has to own the whole thing.

As founder and technical lead at ClaBiTs, that ownership isn't theoretical. I make the architecture decisions, write the code, deploy the infrastructure, and make the product and business calls that come with running a technology company.

I can lead the business conversation, make the architecture decision, and still go deep into the code and infrastructure when necessary.

Career Timeline

2016 — Present

Founder, Team Lead & Senior Software Developer

ClaBiTs LTD

Leads product direction, architecture, and engineering at ClaBiTs — from the school-management platform used by African schools to the fintech, AI, and mobile products built alongside it. Combines hands-on engineering with the product and business decisions that come with running the company.

A Major Differentiator

Artificial Intelligence & Intelligent Systems

Works across the full AI application lifecycle — not just calling a model API, but designing how AI fits into a real product: how it remembers context, retrieves the right information, fails safely, and gets deployed and served in production.

Fintech & Financial Systems

Financial software has different rules than ordinary CRUD applications: correctness, traceability, and security matter more than a polished interface. That distinction shapes how these systems get designed — validation before action, auditable state transitions, and webhook/error handling that assumes external providers will fail.

Mobile Engineering

Flutter is the primary mobile stack — used to ship cross-platform consumer and fintech-adjacent applications that talk to a real backend rather than static demo apps.

DevOps, Infrastructure & Production Engineering

He doesn't just build applications; he can get them running in production.

I don't stop at writing the application. I understand what it takes to deploy, operate, troubleshoot and maintain it in production.

The Kind of Production Problems He Handles

  • Migrating a live production site to a new stack without breaking a legacy system sharing the same database
  • Keeping a `prisma db push` schema-sync workflow from ever touching another application's tables
  • Zero-downtime service restarts via systemd (`Restart=on-failure`) behind an Nginx reverse proxy
  • Issuing and renewing HTTPS certificates (Let's Encrypt/certbot) for a live domain
  • Running the app as a dedicated non-root system user with a locked-down systemd unit (`ProtectSystem=strict`, `NoNewPrivileges`)
  • Webhook signature verification and idempotent handling for third-party callbacks
  • Diagnosing and recovering from deployment and dependency issues on a production VPS

Leadership & Entrepreneurship

Founder / CEO / Technology Leader — ClaBiTs LTD

Building and leading a technology company requires capabilities beyond writing software — product direction, technical decision-making, client relationships, and the judgment to prioritize what actually matters.

Building ClaBiTs

ClaBiTs isn't just a coding project — it's the experience of building technology, a product, and a business at the same time.

Lead by understanding

Understand the problem before directing implementation.

Lead by example

Stay technically capable rather than becoming disconnected from engineering.

Give people ownership

Create room for people to solve problems rather than micromanaging every detail.

Make decisions

Leadership requires making decisions when information is incomplete.

Learn continuously

Technology leaders must keep learning as the tools change.

Build people and products

Successful technical leadership means developing both systems and people.

Beyond Code

Where Technology Meets Business

Technology+Product+Business=Digital Product

Communication

Translates complex technical requirements into language that both technical and non-technical stakeholders can understand.

Ownership

Takes products from concept through engineering, deployment, and ongoing improvement — not just an assigned ticket.

Critical Thinking

Evaluates technical trade-offs, architecture decisions, cost, scalability, and reliability before committing to an approach.

Adaptability

Has worked across AI, fintech, SaaS, education, e-commerce, mobile and infrastructure — comfortable moving between domains.

Client Management

Understands client requirements, translates them into technical solutions, and manages expectations through delivery.

Continuous Learning

Actively explores AI, software architecture, and infrastructure as the tools and best practices evolve.

The Kind of Problems I Solve

“We need a product.”

Design and engineer it, end to end.

“We need an existing system rebuilt.”

Analyze the current system and architect its replacement.

“Our backend doesn't scale.”

Investigate the architecture and performance bottlenecks.

“We need AI inside our product.”

Design the AI application architecture around the real use case.

“We need a banking/payment integration.”

Build the integration and the transaction workflows around it.

“Our application needs to go to production.”

Handle the infrastructure and deployment.
