Tradescene Tech Limited is a private engineering company founded and run by Tony Ngugi (CEO & CTO) and Brenda Kang'acha (COO). We're headquartered in Muranga, with roots in Nakuru City — the place that shaped how we think about commerce, infrastructure, and the businesses we build for.
"Defensive coding with a paranoid-first design. Assume the system will be attacked, assume it will fail, then build the version that survives both."
Operations, clients, and delivery. If a project ships on time and stays on budget, it's because this side of the company kept it honest.
Tradescene exists because too much software in this market is built to demo, not to survive. We watched businesses in Nakuru, Muranga, and across Kenya buy systems that looked fine on a sales call and fell apart the moment a real transaction hit them — or the moment an attacker looked at them twice.
We didn't want to be that kind of company. So we built Tradescene around a simple, uncomfortable premise: every system we ship should still be something we'd be willing to run ourselves, years later, under load, with someone actively trying to break it.
Tony leads engineering with defensive coding and a paranoid-first design posture — the assumption that a system will eventually be attacked, will eventually fail, and needs to keep working anyway. Brenda runs operations, delivery, and the client relationship so that "on time and on budget" aren't marketing words — they're the way we work.
We're a private limited company. We're small on purpose. And we take on fewer projects than we could, because we'd rather deliver a system we can stand behind than a portfolio we can't maintain.
These are the ones we enforce internally, even when they cost us the deal. If a project needs us to break one of them, we'd rather not take the project.
Every system is designed on the assumption that it will be attacked, will be misused, and will fail. Security and resilience are the starting point, not a feature bolted on at the end. This is Tony's line and it's non-negotiable.
We code for the failure cases before the happy path. Input validation, error boundaries, transaction safety, and idempotency are table stakes — not details someone remembers at the end of the sprint.
We quote the price we'll charge and we hold to it. If a project can't be scoped honestly up front, we'll say so before we take your money — not invent a range and bill you to the top of it.
We don't ship and disappear. The team that built your system is the team you call when something goes wrong — because they're the only people who should be answering that call.
Three systems in production that we still maintain, still monitor, and would still build the same way today.
Real-time loss dashboard paired with a Flutter employee app for capturing field evidence, attendance, and compliance documents. Over 60 hardened APIs behind a zero-trust posture.
A central-shop e-commerce system for a Nakuru City retailer — digital storefront, product catalog, M-Pesa integration, and a backend designed to grow with the business.
Multi-warehouse inventory with automated reordering and predictive stock optimization. Replaced spreadsheets with real visibility across operations.
Leads engineering and product. Believes in defensive coding, paranoid-first design, and systems that behave predictably under attack. Writes the code and answers the phone when something breaks — both roles, same person, on purpose.
Runs operations, delivery, and client relationships. Keeps projects on schedule, keeps scope honest, and keeps the client side of Tradescene as dependable as the engineering side. The reason "on time and on budget" isn't a slogan here.
Not vanity metrics. Just the things we can actually point to.
Not a salesperson, not an account manager. If you want to know whether we can help with something specific, the fastest way is to ask the engineer who'd work on it. That's Tony.
