I build the systems people use — and I take them to the street.

Most engineers meet their users through analytics dashboards. I meet mine in person, then go build what I saw.

At Welile I work across engineering, product, and field growth — building software, launching products, onboarding users, and turning real-world friction into systems that scale. Welile is building toward financial identity infrastructure for Africa, starting with rent and expanding into other everyday economic behaviours.

About

I work at the intersection of engineering, product, and growth. I don't write software and wait for users to arrive — I help take products into the market, watch how people actually use them, and build around what I learn.

At Welile that means working on systems touching real money, real businesses, and real households. The core platform helps tenants access rent support, landlords receive rent upfront, agents distribute the service, and partners participate through structured platform programmes. The longer-term direction is to turn everyday economic behaviour into trusted financial identity data that can unlock opportunity across Africa.

The engineering challenge is therefore bigger than building screens. I think about data integrity, transaction flows, reconciliation, identity, permissions, mobile-money integrations, auditability, and operational tooling — while still caring whether a real person can understand and use the product.

What I build

  • Fintech and financial-identity platform features
  • Rent support and repayment workflows
  • Mobile money and payment integrations
  • Cross-platform mobile applications
  • REST APIs and backend services
  • Relational data models, ledgers, and transaction systems
  • Authentication, KYC, sessions, and access control
  • Internal dashboards and operational tooling
  • Product experiences built from field research

What I run

  • Field acquisition and user onboarding
  • Product distribution and market expansion
  • Tenant, landlord, and agent education
  • Turning field observations into product requirements
  • Launching and supporting new digital products
  • Closing the loop between users, operations, engineering, and roadmap

Current scale

66,000+ users across the Welile ecosystem, spanning multiple products that serve different parts of the customer and operational journey.

Work at Welile

Building financial identity infrastructure, starting with rent. Welile is a technology-enabled rent platform that helps tenants access upfront rent payments, landlords receive rent on time, and users build a verified history of their financial behaviour. The longer-term vision is to transform everyday economic activity into trusted financial identity data.

Engineering & Product

  • Build and maintain customer-facing fintech products across web and mobile
  • Design payment, repayment, wallet, receipt, verification, and account workflows around real operational constraints
  • Work with mobile-money and banking payment rails, including MTN Uganda, Airtel Uganda, and Equity Bank Uganda
  • Build transaction-aware systems where reconciliation, auditability, permissions, and data integrity are core product requirements — not afterthoughts
  • Turn field observations and user feedback into product requirements and shipped features
  • Work across the stack: TypeScript, JavaScript, React, React Native, Node.js, PostgreSQL, APIs, and cloud tooling

Growth & Field Operations

  • Support acquisition and onboarding of tenants, landlords, agents, and partners
  • Take products into the field and use direct user interaction to identify friction analytics alone cannot explain
  • Bridge the gap between engineering, operations, sales, and the people actually using the platform
  • Contribute to product launches and market distribution as Welile expands beyond a single rent product

Product Ecosystem

The platform is moving from a single rent product toward a broader set of financial and asset-related services.

Product Role in the ecosystem
Welile Core rent technology platform connecting tenants, landlords, agents, and partners
Welile App Mobile-first tenant experience for rent support, repayments, and account services
Welile Receipts Digital receipt and payment-record experience supporting verified transaction history
Welile Car Vehicle-services product line — a web platform for service management and records, plus a React Native companion app for owner profiles, maintenance history, and service workflows
Welile Drive Save-to-Own vehicle platform combining a digital wallet, vehicle inventory, savings milestones, and financing workflows

Internal products — repositories may be private or limited in scope.


Personal Projects

Project What it does Stack Type
Tenant Portal Responsive interface for tenant and property management, replacing the spreadsheet-and-group-chat workflow most small landlords rely on. Built from the same field observations that drive my work at Welile. HTML CSS JavaScript Web
Password Generator Browser-based generator for cryptographically strong passwords with configurable length, character sets, and exclusion rules. Runs entirely client-side — no password ever leaves the device. HTML CSS JavaScript Utility
Password Generator Mobile The same generation engine ported to mobile in TypeScript, with a touch-first interface and clipboard integration for on-the-go credential creation. TypeScript React Native Mobile
Sudoku Game Playable Sudoku with a constraint-propagation and backtracking solver — an exercise in algorithmic problem-solving and recursive search. Python Algorithms

Foundations & Practice

Deliberate practice repositories — where I work through fundamentals before applying them in production code.

Focus Repository What it covers
Python Python Core Concepts Data structures, OOP, file I/O, standard library depth
Web HTML & Web Fundamentals Semantic markup, layout systems, accessibility, responsive design
Data Data Extraction Utilities Scraping, parsing, transformation, and validation pipelines
Algorithms Programming Challenges Complexity analysis and problem sets across common patterns

Currently Deepening

Area Why it matters to what I'm building
Advanced TypeScript Generics and discriminated unions that make invalid payment states unrepresentable
Distributed Systems Idempotency, exactly-once semantics, and reconciliation across unreliable payment rails
Backend Architecture Service boundaries and caching as transaction volume grows
Cloud & DevOps Containerized deploys and CI/CD so releases stop being manual events
Growth Engineering Instrumentation and funnel analysis, so field intuition gets checked against data

Open To

Based in Kampala, Uganda — open to on-site, hybrid, and remote.

I'm interested in conversations about:

  • Engineering roles — full-stack, mobile, or backend, on teams shipping to real users
  • Fintech and financial identity — particularly mobile money, payments, and financial inclusion in emerging markets
  • Product-and-growth engineering — where engineering, distribution, and firsthand user knowledge reinforce each other
  • Open source — contributions to tools I use, especially React Native and TypeScript
  • Technical mentorship — in both directions
