I build the software a business runs on.
Custom business web apps — CRM, e-commerce, AI automation, and business platforms — engineered full-stack, delivered fast with AI-assisted development, grounded in fundamentals.
From business problem to production system.
Full-stack engineer specialising in CRM, ERP, and SaaS platforms — using AI as an accelerator, not a replacement for engineering fundamentals.
My strongest work is turning complex business processes into practical, production-grade software systems.
I'm a full-stack software engineer focused on scalable business software — CRM, ERP, SaaS platforms, and workflow-driven applications — leveraging AI-assisted development to accelerate delivery and solve complex technical problems.
I'm fluent in JavaScript/TypeScript and Python, and comfortable across the whole stack: React, Next.js, Node, Express, FastAPI, Django, Prisma, SQLAlchemy, PostgreSQL, Firebase, Supabase, Redis, and REST APIs — from frontend interfaces to backend services, databases, auth, cloud infrastructure, deployment, and architecture.
I use AI as an engineering accelerator, not a replacement for fundamentals — combining AI coding tools, LLM APIs, and agent-assisted development with solid engineering principles to move quickly across unfamiliar codebases and new technologies without being locked to one ecosystem.
My focus is the parts where business rules and data integrity matter most: role-based access control, approval and financial workflows, auditability, controlled state transitions, and third-party integrations — with real attention to edge cases, security boundaries, and the operational realities of production.
I start from the business problem, challenge assumptions, and design systems that stay reliable and maintainable as the organisation grows. The goal isn't just software that works — it's software that solves the right problem and scales with the business.
Product-first
Understand the business problem and the workflow before choosing the technical solution.
Full lifecycle
Requirements, architecture, build, testing, deployment, and monitoring — not just the code.
AI-accelerated
AI coding tools and LLM APIs layered on engineering fundamentals — fast, not fragile.
Production-grade
Reliable, maintainable, secure, and scalable — built for the realities of running in production.
Systems, not demos.
Real production platforms I've engineered, plus live builds you can open and inspect. 2024–2026.
A note on the confidential work below:my strongest systems are internal business platforms built under NDA, so they're described by capability and architecture — not by client or data. Happy to walk through the design and engineering in a call.
