What I build

End-to-end software development — from architecture and database design through to deployment and ongoing maintenance. Each engagement is direct with me, not delegated to a junior team.

01

Web Development

From marketing sites and landing pages to complex web applications and customer portals — built with Next.js, TypeScript, and a focus on performance, SEO, and long-term maintainability.

Capabilities

Business websites and marketing sites

Customer and client portals

Admin dashboards and internal tools

02

Software Development

Not every business problem fits an off-the-shelf product. I build custom software that maps directly to how your business actually works — from internal tools and workflow systems to APIs and data pipelines.

Capabilities

Custom web applications

Internal tools and workflow systems

REST APIs and backend services

03

SaaS Development

Building a SaaS product requires decisions that are hard to reverse — data architecture, multi-tenancy, billing, access control. I design these foundations correctly from the start, so you're not rebuilding them later.

Capabilities

Multi-tenant architecture with full data isolation

Authentication and role-based access control

Subscription billing integration

04

Mobile App Development

I build mobile apps with Flutter (iOS + Android from a single codebase) and React Native — connected to production-grade backends, optimised for performance, and deployable to the App Store and Play Store.

Capabilities

Cross-platform iOS and Android (Flutter)

React Native applications

Offline-first apps with local data sync

AI Development

AI is most valuable when it solves a specific, measurable problem: reducing manual data entry, improving accuracy, generating content at scale, or surfacing insights from existing data. I integrate AI where it genuinely helps, not as a feature checkbox.

Capabilities

OpenAI and Google Gemini API integration

Intelligent document processing

AI-powered analytics and reporting

ERP & Internal Systems

Generic ERP systems are often too rigid, too expensive, or built for a different industry. I design and build custom ERP and internal systems that precisely match your operational processes — from manufacturing and inventory to scheduling and reporting.

Capabilities

Multi-tenant ERP architecture

Inventory and stock management

Production scheduling and machine load balancing

Business Automation

If your team is running operations on spreadsheets, WhatsApp groups, or manual data entry — I can design and build software that handles it automatically. The goal is not just to digitise existing processes, but to design them better.

Capabilities

Workflow automation and approval systems

Scheduled jobs, cron tasks, and background workers

Data sync between systems and APIs

Why work with me directly

Senior-level engineering, no intermediary

You work with the person who writes the code

Every project I take on is architected and built personally. Your requirements go directly to the developer, not through a project manager.

Architecture-first thinking

I design data models, system boundaries, and technical decisions before writing code — avoiding the expensive mistakes that happen when you build before you plan.

Production-grade from day one

Every project ships with CI/CD, monitoring, error tracking, and deployment automation — not as an afterthought, but as part of the build.

Long-term technology partner

I remain available after launch for maintenance, new features, and integrations. Software is not a one-time project.
