London · United Kingdom · GMT
London does not have a shortage of agencies. It has a shortage of agencies that put senior engineers on the work and keep them there. GeekyBugs runs from a UK base in Hertfordshire, inside the M25 commuter belt and on London time all day, with engineering led out of a studio that has been shipping since 2018. You get people who join your standups, not a vendor who sends a status email on Fridays.

How we cover London
UK entity established 2023, based in Welwyn Garden City — roughly 25 minutes from King's Cross.
Full working-day overlap with London. No handover windows, no waiting overnight for an answer.
On-site in London for kickoff, quarterly reviews, and whenever a workshop beats a call.
Engineering delivered from our Lahore HQ, led and accounted for from the UK.
The case for us
London runs on financial software, and financial software is unforgiving. We have built money movement, card management, lending and banking integrations — Stripe, Plaid, Unit, Mastercard, PCI-aware architecture and CQRS systems where the audit trail matters as much as the feature.
No juniors billed at senior rates, and no bait-and-switch after onboarding. You interview every engineer before they start. The person in that interview is the person who writes your code.
A senior engineer in London carries salary, employer NI, pension, recruitment fees and a desk. We place the same calibre of engineer inside your team at a flat monthly rate, scalable up or down with two weeks' notice.
A written report every Friday, a senior reviewer on every pull request, same-day escalation when a date comes under threat. If something slips you hear it the day we see it, with a re-plan attached.
Capabilities
Payments, lending, cards, cross-border flows and banking integrations, built to survive an audit rather than a demo.
Production web applications and the API infrastructure under them, built to be maintained for years rather than handed over and abandoned.
AI inside real products, not demos — retrieval pipelines, agents and vector search shipped into healthcare, coaching and triage platforms.
Enterprise Mendix at the scale global manufacturers run it: business process automation, Azure AD single sign-on, multi-region deployments.
Cross-platform from one codebase where that serves the product, and native where performance is not negotiable.
One specialist or an embedded team, inside your management and your process. No agency layer in between.
Frequently asked questions
Our UK office is in Welwyn Garden City, Hertfordshire, about 25 minutes by train from King's Cross — not in central London. We work London hours, meet clients in London in person, and our UK entity has been established since 2023. Engineering is delivered from our headquarters in Lahore under UK-based accountability. We would rather tell you that plainly than claim a serviced-office address in the City.
A senior developer hired in-house in London typically costs well over £70,000 before employer National Insurance, pension, recruitment fees and equipment. Our senior engineers are a flat monthly rate per engineer, with a 10% reduction across the team at four engineers or more and a dedicated project manager included at that size. There is no recruitment fee and no notice period beyond two weeks.
We build software for financial businesses and have delivered payments, lending and banking systems with the controls those products require — audit trails, access control, OWASP practices from the first commit, and penetration testing before launch. We are an engineering studio, not a compliance consultancy: your regulatory obligations stay with you and your advisers, and we build to the requirements they set.
One call to scope the problem, a written proposal within 48 hours, and engineers matched to your stack and domain within about a week. You interview them before anyone starts.
You do, from the first commit. Everything is delivered documented and tested, in your repositories, so your own team can pick it up whenever you want to bring it in-house.
Founders building a first version, scale-ups adding capacity faster than they can hire, and enterprises that need a specific capability. Our longest client relationship runs to ten years; the largest embedded team is twelve engineers.
