SERVICES.

A whole engineering team in one person: design through deployment, no handoff to lose detail in. Here's what I build, how I work, and the ways we can engage.

What I build

(05 services)
01

Custom web apps

ReactNext.jsNodePostgreSQL

Dashboards, client portals, booking systems, internal tools: software built around how you actually operate, not how an off-the-shelf product wishes you did.

  • Discovery doc & data model
  • Full design, no separate designer
  • Front & back end, end to end
  • Deployment & monitoring

Ideal for: a business outgrowing spreadsheets, manual ops, or a tool that nearly fits.

02

AI features & agents

LLMsRAGMCPAgents

Assistants that answer 24/7, agents that kill repetitive work, retrieval over your own documents, built with the guardrails that keep them useful once real users arrive.

  • Eval harness before launch
  • Fallbacks & honest degraded states
  • Token-cost budgets & alerts
  • Versioned, reversible prompts

Ideal for: teams who want AI that holds up in production, not a demo that breaks in week two.

03

API integrations

StripeWebhooksCRMsCalendars

CRM, payments, email, calendars and the spreadsheet everything secretly runs on, wired into one connected system that updates itself instead of someone re-typing it.

  • Reliable two-way sync
  • Idempotent, retry-safe webhooks
  • Error alerting you can trust
  • Clear docs for your team

Ideal for: tool sprawl, double data entry, and systems that don't talk to each other.

04

Performance & SEO audits

Core Web VitalsSEOAccessibility

Find what's slow, what's hurting rankings and what's quietly killing conversions, then fix it, with before-and-after numbers rather than vibes.

  • Prioritised findings report
  • Core Web Vitals & SEO fixes
  • Accessibility (WCAG) pass
  • Measured before/after impact

Ideal for: a site that loads slowly, ranks poorly, or loses people at the last step.

05

Ongoing support

RetainerMonitoringIteration

A developer on call who already knows your codebase. Updates, monitoring, and a steady stream of small improvements that compound, instead of a product that quietly rots.

  • Agreed response times
  • Uptime & error monitoring
  • Monthly improvement work
  • One person, no re-onboarding

Ideal for: a live product that needs care, not a contractor who vanishes at launch.

How I work

The difference

A whole team in one person

Strategy, design, front end, back end, deployment: one head holding the whole picture. Nothing gets lost in a handoff because there isn't one.

Fixed price, not hours

You get one number before we start, agreed after discovery. No ticking meter, no surprise invoice. The risk of scope is mine to manage, not yours.

Code in your repo, day one

I push to your repository from the first commit. No black box, no hostage situation. You can see progress daily, and you own everything throughout.

Async by default

Written end-of-day updates instead of standup theatre. You stay fully in the loop without your calendar filling up with meetings about the work.

Reply within a day

I read and answer every email myself, usually same-day. You're talking to the person doing the work, never an account manager relaying a message.

Production-grade by default

Fallbacks, retries, monitoring, the unglamorous plumbing. The boring work that decides whether a demo survives contact with real users.

Ways to work together

Three shapes
Shape 01

Project

A defined build with a fixed scope and a fixed price, agreed after a short paid discovery. The default for anything from a new app to a focused feature.

Best when you know roughly what you need and want a clear cost and timeline.

Shape 02Most popular

Sprint

A focused week or two aimed at one concrete outcome: a prototype, an AI proof-of-concept, an audit with fixes. Fast, fixed, and low-commitment.

Best when you want to test an idea or unblock something specific, quickly.

Shape 03

Retainer

An ongoing arrangement with agreed response times and a monthly block of work: a developer on call who already knows your codebase inside out.

Best when you have a live product that needs steady care and improvement.

Questions, answered

FAQ
How much does it cost?
It depends on scope, but you'll never guess at it. After a short discovery I give you one fixed price for the whole project before any build starts. No hourly rate, no meter running, no surprise invoice at the end.
How long will it take?
A sprint is one to two weeks. A typical project runs a few weeks to a couple of months depending on complexity. Discovery produces a real timeline, not a hopeful one, and async daily updates mean you always know where it stands.
Do I own the code?
Completely, from commit one. I work in your repository, so the code is yours throughout, not handed over at the end, and never held hostage. If we ever stop working together, you lose nothing.
What if I'm not technical?
That describes most of my clients. You don't need to speak engineering. That's my job to translate. I'll explain trade-offs in plain terms and handle every technical decision so you can stay focused on your business.
Do you work with existing code or only new builds?
Both. I take on greenfield projects and inherited codebases alike, including the ones a previous developer left in a state. An audit is often the cleanest way to start if you're unsure what you're sitting on.
What happens after launch?
Launch is a milestone, not an exit. I monitor for the rough patch right after go-live, and many clients move onto a retainer for ongoing improvements. Software that keeps getting better is the whole point.

In a client's words

Proof

“Excellent is the only word for his skill set. He did everything I wanted, fast, and went beyond what I expected. I was so impressed I doubled the rate I'd budgeted for the project.”
