Practitioner-led technical documentation and certification that captures, structures, and transfers institutional knowledge, helping engineering teams reduce critical-person dependency and onboard new engineers faster. Trusted by Tier 1 banks and fintech since 1990.
The problem comes when only one person understands how something works. Projects slow down. Onboarding takes longer. Operational risk starts creeping in.
Most of the time it isn’t because anyone has done anything wrong. Systems get built under time pressure, the person who built them moves on, and the documentation that was going to get written never quite does. When that person leaves, so does the system or a big enough part of it to hurt.
This is critical-person dependency. It’s the quiet problem inside almost every engineering team we work with.
Banks don't need better documentation. They need documentation written by people who've actually built systems like theirs.
Every Mallon engagement is led by practising engineers who've worked on trading systems, market data platforms, payments infrastructure and risk technology. That experience means the documentation reflects how engineering teams really work, not how someone imagines they work.
We ask better questions, spot engineering risks sooner, and produce documentation your teams actually trust.
A technical writer captures what you tell them. A practising engineer notices what you didn't.
Every engagement starts by understanding how your engineering estate really works.
We work alongside your engineers to uncover the decisions, dependencies and undocumented knowledge that sit behind critical systems. Only then do we produce documentation your teams will actually use.
Every engagement is scoped to your systems, but the deliverables typically include:
Written by practitioners, reviewed and signed off by your internal leads.
Structured sessions to extract and share what your team already knows.
A defined standard for what "productive on this system" actually means.
The artefacts organised so new joiners can navigate them without a guide.
Mallon's smart documentation and learning platform. Keeps the artefacts current and the risk indicators visible.
If any of that sounds familiar, this is the work we do.
Once the documentation exists, two things need to happen. People need to be able to prove they've absorbed it. And it needs to stay current.
Certification isn't a completion badge. Each engineer, from graduate hires to laterals to senior contributors, is certified against a standard your team defines with us. It's a signal your Head of Engineering can trust when allocating work.
To keep the artefacts alive, we host them in Semlr™, Mallon's smart documentation and learning platform. Semlr flags what's going stale, tracks who's engaging with which parts of the system, and gives you a way to measure whether the risk has actually reduced quarter on quarter.
"Before Mallon, our developer knowledge lived in silos. Mallon's unique documentation framework and ongoing updates provide cross-enterprise structure and consistency, and alongside a tailored certification programme, ensures every developer, from graduates to senior hires, is contributing quickly and effectively."
A technical writer captures what you tell them. Our engineers uncover what nobody has thought to write down. Every artefact is authored or reviewed by a practising engineer who has built systems in the same problem space, so the output reads like something your team would actually use.
Heads of Engineering, CTOs and technology leaders at investment banks, retail banks, asset managers and fintech scale-ups. Usually the buyer is the person who has already had the "what happens when Fred leaves" conversation and needs to do something about it.
Twelve to sixteen weeks for a single-platform documentation and certification cycle. Longer for multi-system estates or post-acquisition integrations. We run alongside your team, not instead of it — the roadmap doesn't stop.
Certification against a standard your organisation defines with us. Usually a demonstrated ability to work productively in a target system, verified through practical assessment against the documentation we've produced. Not a course-completion badge.
Yes. Mallon has worked with Tier 1 investment banks, retail banks and asset managers since 1990. Documentation and certification frameworks are designed with your operational resilience and third-party risk teams in mind from day one.
Yes. The problem is often sharper at scale-ups — one or two engineers built the platform, the business now depends on it, and the founder wants to be able to sleep. Same framework, smaller estate, faster cycle.
Two options. Either your team maintains the documentation using the framework we've established, with an annual review from us. Or the artefacts live in Semlr™ and the risk indicators stay visible in your engineering KPIs. Most clients start with the second and move to a blend.
Every engagement starts with a conversation, not a proposal. Tell us which system is keeping you up at night, and we'll come back to you within two working days.
