Services
Every engagement combines one or more services, scoped clearly with written deliverables and checkpoints. Whether it's a single-day review or a multi-week build, I agree on outcomes upfront.
Move outdated systems into clean, testable .NET or modernised VBA. The outcome: you get systems you understand, reduced operational risk, faster change cycles, and better performance.
Build workflows that eliminate manual effort in reconciliation, reporting, data processing. Outcome: hours saved daily, accuracy improved, you focused on strategy not data entry.
Connect platforms and APIs reliably. Outcome: clean data flow, automated validation, clear audit trail, problems surface early before they impact operations.
Get honest review of code quality, testing practices, and architecture. Outcome: clear roadmap for improvement, prioritised by impact and effort, so you know where to invest next.
Delivery model
Understand your goals, current systems, constraints, and what success looks like. You get a scoped plan with realistic estimates, architectural direction, and quick wins. Investment upfront prevents misalignment and rework later.
Chargeable engagement to create a detailed design proposal. Technology stack, architecture diagram, database schema, API contracts, and delivery timeline. You review, approve, and I'm ready to start—aligned on exactly how the solution will work before development begins.
Review findings together. Agree on scope, deliverables, fees, and timeline in writing. No ambiguity, no scope creep. Everything documented before code starts.
Code delivered in small, testable increments. Weekly checkpoints. You see progress early, steer direction before completion, stay in control throughout.
Walk through completed work together. Confirm it meets agreed requirements. Formal sign-off before handover and payment processing.
Deliverables released when payment clears. You get all source code, design documentation, tests, runbooks, and knowledge transfer. 30-day defect warranty covers any bugs found after sign-off.
Selected work
Client names are confidential, but every example below is from real delivery.
Built a VBA-based tactical solution for a UK bank to standardise forecasts, resource plans, and actuals across the group. Finance teams saved time on month-end reporting and visibility improved across multiple offices.
Designed and maintained OpenText Captiva workflows processing high volumes of documents monthly. Built IBML scanner configuration, validation rules, error handling, and integration to downstream systems with automated exception handling.
Led operator training (soft skills, software, hardware), UAT, and go-live for enterprise document capture across multiple sites. Trained operators to competency, managed deployment successfully, and created documentation to support retention.
Configured IBML scanners for high-performance document ingestion, developed automation for consistent throughput. Improved efficiency through optimised feed mechanisms and reduced manual intervention significantly.
Built VBA tools and reporting for a banking group to manage resource planning, volume tracking, and operational metrics across multiple business units. Automated month-end reporting cycle significantly via consolidated data feeds and dashboards.
Delivered years of continuous .NET development for a fintech client. Built mission-critical systems from architecture through to operation, evolved tech stack across major framework upgrades, maintained stable production operations.
Capabilities
This is a representative selection rather than an exhaustive list of every framework, package, and tool I work with. Each engagement uses the right combination for your stack and constraints.
Development platform
Enterprise-grade tools, processes, and practices. Every engagement includes version control, CI/CD, testing, and documentation as standard. AI-assisted development is available on request, with full human review of every deliverable.
Clear documentation, secure collaboration, integrated project coordination. AI assistance for requirements, documentation, and team comms — keeping everything aligned and auditable.
Reliable, scalable, enterprise-secure infrastructure. App Service, Functions, SQL Database, DevOps pipelines built in. Systems stay running, scale easily, comply with your requirements.
Source control with automated CI/CD, AI-assisted code review (if requested), pull request workflows. Every commit is tracked, every change reviewed, deployments are reliable and traceable.
Full IDE for .NET, unit testing, debugging. VS Code for rapid iteration. Both with AI assistance. Same code quality standards, faster feedback loops.
CI/CD pipelines built in from day one. Automated builds, tests, deployments. Your code goes from commit to production reliably, repeatably, with a clear audit trail.
High-end workstation with CPU, GPU, and NPU acceleration for fast builds, responsive tooling, and AI-assisted development. No waiting for compilation or deployments to slow you down.
Value
AI is a powerful tool, but it's not a replacement for judgment and accountability. Here's what you get:
A named professional responsible for quality, scope, and outcomes. Not algorithmic decisions divorced from business reality.
I ask the right questions before coding. Trade-off decisions based on what matters to your business, not code optimization extremes.
You own the solution independently. Documentation and knowledge transfer included. Not locked into ongoing support contracts.
Requirements engineering, architecture decisions, and risk assessment require human judgment. AI accelerates delivery; I ensure quality.
All output fully tested and reviewed. Quality bar as rigorous as hand-written code, backed by a 30-day warranty.
Fixed scope, written estimates, realistic timelines. Clear deliverables upfront. You know what you're getting and what it costs.
Share what you're working on and I'll respond with a clear next step.
