DGDavies Ngwiri Gitau

Senior full-stack engineer / cofounder / consultant

I build ambitious products with founder energy and engineering discipline.

I work across product, code, and execution, shipping mobile apps, backend systems, AI workflows, commerce experiences, and venture-grade software for teams that need sharp thinking and real momentum. This site is meant to show both what I build and how I think about building it.

Proof

Built with teams where quality, speed, and business reality all mattered.

My background spans backend architecture, mobile delivery, venture product thinking, QA oversight, and team leadership. The through-line is simple: make the product better, faster, and harder to break.

Selected work

Product taste, systems depth, and commercial pressure. That is the intersection I like.

I do my best work when the product is real, the constraints are messy, and the team needs someone who can turn ambiguity into a sharp execution plan.

01

Coinscentric

Founder-side fintech build

2023 - Present

A finance platform shaped around clarity, behavior, and access. The product combines money tracking, financial education, advisor access, and machine-learning-assisted spending insight for a more useful view of personal finance in Africa.

Defined a product direction that goes beyond budgeting into financial literacy and better money behavior.

Services

I can step in as a builder, operator, or technical partner.

If the brief needs clean execution, better architecture, stronger product judgment, or a technical lead who can also think commercially, that is the lane I operate in.

Founder-side engineering

I help ventures move from rough ambition to a product that can actually meet users, investors, and the market with confidence.

  • Zero-to-one product definition and technical direction
  • MVP scoping without building the wrong thing
  • Hands-on execution when the team is still small

Mobile and product frontends

I build interfaces that feel deliberate, usable, and commercially aware across Android, Flutter, React, Vue, and modern web stacks.

  • Cross-platform mobile delivery for iOS and Android
  • Responsive web experiences with strong interaction quality
  • Figma-to-code translation without losing the product intent

Backend and platform systems

My backend work is shaped by scale, uptime, and operational reality. I like systems that stay calm when usage and complexity start climbing.

  • Node.js, Spring Boot, Python, Go, and API architecture
  • Cloud, Linux, containers, and production-minded delivery
  • Database design across SQL, Postgres, MongoDB, Redis, and DynamoDB

Consulting and technical leadership

I step in where technical execution needs adult supervision, sharper product judgment, or a builder who can also speak business.

  • Architecture reviews and delivery rescue
  • Team leadership, code reviews, and process cleanup
  • High-trust consulting for startups and operating teams

Code footprint

GitHub shows the long arc: mobile, backend, telecom, commerce, and infrastructure.

The public repo history is not just a pile of side projects. It shows years of building across different product categories and technical layers, from logistics and ecommerce to voice systems, utilities, and mobile architecture.

Writing

Articles, breakdowns, and operator notes from the delivery side of the work.

This is where I unpack the thinking behind the work: what shipped, what changed, what held up, and what other teams can actually reuse. Over time, it will grow into a sharper editorial layer for product, engineering, and operating judgment.

What trustworthy credit AI should look like in Kenya

In Kenya, credit AI will only deserve trust if it uses proportionate data, explains decisions in plain language, respects uncertainty, and gives borrowers a real path to question harmful outcomes.

What makes credit AI trustworthy in the Kenyan lending context?

A trustworthy system uses proportionate data, explains decisions in plain language, accounts for thin-file uncertainty, and gives borrowers a real way to review or challenge harmful outcomes.

What trust looks like in Coinscentric

Coinscentric is not being shaped around finance dashboards first. It is being shaped around helping users feel oriented, informed, and supported enough to trust the product with real financial decisions.

How does Coinscentric turn trust from an abstract fintech principle into an actual product direction?

By treating clarity, financial education, advisor access, and explainable insight as core product surfaces instead of secondary features.

Trust is the real interface in fintech products

In fintech, users are not only evaluating features. They are deciding whether the product deserves access to their money, habits, and attention. Trust is part of the interface.

What makes fintech products feel trustworthy before a user has any history with them?

Clear language, predictable flows, visible safeguards, and calm design do more for trust than complex feature sets or aggressive growth mechanics.

Current lens

I keep coming back to domains where software changes the operating model.

The nearby work shows the pattern: applied AI, finance, commerce, and health. I like spaces where good product judgment has real downstream leverage.

Applied AI

Voice systems, operational automation, and AI-assisted workflows that solve practical business bottlenecks.

Fintech

Products that make financial behavior, literacy, and access more usable for everyday people and growth-stage teams.

Commerce

Sharp brand and conversion experiences for businesses where trust, taste, and flow shape revenue.

Digital health

Care operations and patient journeys designed for local markets where clarity and speed matter just as much as features.

Contact

If you need a world-class builder who can think like a cofounder, let's talk.

I take on select consulting, technical leadership, and product build engagements. The best outreach is direct, clear, and tied to something real you want shipped.
