Need to ship a product on a fixed deadline?
End-to-end product delivery: requirements analysis, architecture, frontend, code review, launch. One point of accountability across the build.
Senior Frontend Engineer
Open to new projects
Products delivered
on the agreed date.
Over eight years delivering products in fintech, SaaS and real estate. I'm strongest on the interface your customers actually touch. When the project needs it, I'll own the full product: architecture, release process, launch.

01What I do
Where I help
Four areas I am usually brought in for. Most projects need two of them at once.
Multiple product teams, inconsistent UI?
A shared library of buttons, forms, navigation and modals, reused across every product team. One source of truth, faster delivery, fewer inconsistencies between products.
Team missing its release rhythm?
I step into a stalled team and restore the cadence: hiring, onboarding, defining a predictable release process, and running the first planning cycles personally.
Major technical decision coming up?
A second opinion before you pick a tool, lock in an architecture or invest in performance. Advice before the decision is always cheaper than rework after.
02Selected work
Projects
Three case studies from the last four years. Each one started the same way: an honest look at what was actually broken, before any code was written.
Fintech Product Launch
Fintech · Team leadership · Release process
30
days to ship
Joined a payment-processing product that was already four months behind schedule. Two developers on the team, no functional release process, no environment to validate changes before customers saw them, and no one on the team could give a reliable launch date. The client and the CEO had both run out of patience.
- Team scaled from 2 to 8 members across roles
- First production release delivered in 30 days, recovering a four-month delay inherited from before I joined
- Release process stable from week one, with zero emergency rollbacks in the first quarter
- Releases settled into a weekly cadence — predictable enough for the client to plan integrations around it
Design System & Component Library
SaaS · Design system · Scale
3×
faster delivery
Three SaaS products under the same brand, each built and maintained separately, each rendering the same button slightly differently. Every new feature meant rebuilding components that two teams had already built before. The design team was spending half the week resolving inconsistencies instead of designing.
- Three products unified on a single shared library — consistent buttons, dialogs and form fields throughout the entire brand
- Delivery speed for new features increased approximately three-fold compared to the pre-library baseline
- Cross-product inconsistencies reduced to zero: every component maps directly to a Figma design and a live gallery entry
- The design team recovered approximately 40% of their working week and reinvested it into product discovery
Real Estate Platform from Zero
Real estate · Architecture · Shifting requirements
0
missed deadlines
A new platform without documented requirements, a fixed launch date committed to an external partner, and stakeholders whose priorities changed week to week. The first meeting I attended contained three conflicting definitions of the minimum viable version — each actively defended by a different stakeholder.
- Translated raw stakeholder input into concrete, prioritised business goals within the first week
- Designed and built the platform from the ground up alongside the team
- Requirements continued to evolve throughout the build. The launch date held.
- Launched on the committed date, with the agreed scope, and no critical incidents in the first week
03How we work
The process
Four stages from the first call to the handover. Every one of them is here because cutting it is where projects usually miss their date.
01
Discovery call, 30 minutes
We discuss the product, the team and what is standing in the way. I ask the questions I need to determine whether I am the right fit. You leave with a clear answer and no sales pressure.
02
Analysis before implementation
Before any code is written, I document the problem, the risks and the plan. A few days spent here is the difference between a real launch date and one that keeps slipping.
03
Transparent delivery
Weekly updates covering what has been delivered, what is next and what I need from you. No dashboards to chase. If something is at risk, you hear it from me first.
04
Launch and proper handover
A production-ready product and documentation your team will actually use. I remain involved for two weeks after launch to ensure the handover holds.
Ready to talk it through?
A 30-minute call is usually enough to see whether we are a fit. No sales, no commitment.

05About
Who you will be working with
8+ years on production frontends in fintech, SaaS and real estate. Frontend Engineer by trade. I'll own the architecture, release process and handover when the project needs it.
Hired most often for three things: fixed-deadline product launches, shared design systems across multiple product teams, and restoring release cadence in stalled teams. Most engagements need two of the three at once.
Every project starts with a written analysis: problem, risks, plan, cost. Single biggest reason my projects hit their delivery dates.
Standard delivery: product live on the agreed date, code your team can keep building on, and a clear owner all the way through to the handover.
