Custom software for real operations

Software designed around how your organisation actually works, from data model and backend logic to the interface people use every day.

I work from the problem outward: understand the process, model the data, then build and deploy a system that is secure, maintainable and ready to grow.

• Requirements discovery and system design
• Backend architecture in Python and Django
• Secure, documented deployment on Linux servers

Systems that replace spreadsheets and paper records with one reliable place for operations, records and reporting.

Typical scope includes role-based access, workflows, notifications, dashboards and exportable reports.

• Role-based access for staff and managers
• Automated reminders and notifications
• Operational and financial reporting

Modular back-office systems that connect finance, inventory, sales and operations around a single database.

I build these module by module around your operations rather than forcing them into a generic package. This is a capability I can deliver, and I will tell you plainly where an existing product would serve you better.

• Modular design that grows one department at a time
• Shared data model and audit trail
• Integration with payments and existing tools

Tools to record customers, track every interaction and follow up consistently.

Contact records, enquiry pipelines, notes, reminders and reporting, shaped to your sales or service process.

• Customer and contact records
• Enquiry and follow-up tracking
• Reports on activity and outcomes

Fast, accessible and secure web applications, built as real software rather than brochure pages.

Server-rendered, responsive interfaces with careful validation and clear user journeys, on a database-backed foundation.

• Responsive, accessible interfaces
• Server-side validation and secure sessions
• Search, dashboards and user accounts

Clean APIs and dependable integrations between your systems and the services you rely on.

I design REST APIs, connect third-party services and handle failures, retries and security properly.

• REST API design and documentation
• Third-party and payment gateway integration
• Webhooks, retries and error handling

Mobile money and payment integrations that confirm, record and reconcile payments correctly.

Experience integrating M-Pesa into platforms for rent, bundles and marketplace payments.

• M-Pesa integration
• Payment status tracking and receipts
• Safe handling of callbacks and duplicates

Automation that removes repeated manual work: notifications, approvals, reports and chatbot assistance.

I automate the steps people repeat, from automatic email and SMS to approval workflows and AI-assisted support.

• Workflow and approval automation
• Automated email and SMS notifications
• AI chatbot integration

Applications built on a carefully modelled relational database, with performance and integrity in mind.

Schema design, migrations, indexing and query optimisation for systems that hold important records.

• Relational data modelling in MySQL
• Migrations and data integrity
• Query and performance tuning

Ongoing care for software that is already in use: fixes, upgrades, performance work and new features.

Audits of existing systems, security and dependency updates, optimisation, and incremental improvement without disrupting users.

• Performance and security review
• Feature additions and refactoring
• Dependable support after launch
