I'm Frederick — a full-stack developer specialising in ASP.NET Core, Blazor and modern .NET. I work with product teams that need someone senior enough to own a slice of the stack end-to-end, without the overhead of a full hire. Bilingual (EN/FR), based in Yaoundé (GMT+1) — perfect overlap with EU / UK working hours.
You're 5-50 engineers, shipping to real customers on ASP.NET Core / Blazor. You need extra senior throughput on a focused workstream — a new module, a perf-critical refactor, an API design — without diluting your team's focus.
You have a validated idea and a real timeline. You want a technical partner who owns delivery end-to-end, communicates plainly, and hands over clean code you can grow on. I ship Blazor Server MVPs in 4-8 weeks.
Stuck on ASP.NET Framework 4.x, Web Forms, or an old .NET Core LTS? I map the migration path, de-risk the hard parts, and either drive the upgrade or coach your team through it.
You're a JS/PHP agency that just won a .NET contract. Bring me in as a white-label senior engineer to deliver it without derailing your team's roadmap. Discreet, contract via your entity.
From spec to production Blazor Server app: auth, data model, core flows, admin panel, deploy pipeline. You get a working product you can put in front of real users. Fixed timeline, weekly demos.
Design and ship a production API — REST or GraphQL — with auth, tests, CI, and observability wired in. Ideal when your product needs a solid backend fast and you don't want a junior to learn on it.
A 2-week deep dive on your legacy .NET codebase. I deliver a written migration plan: what breaks, what stays, what to rewrite, effort estimates, and a de-risked execution sequence. Optional follow-up execution.
30 min video call. We map your goal, constraints, timeline. If we're not a fit, I say so and refer you elsewhere.
Within 48h: written scope, timeline, price, deliverables. Two options when it helps you decide (e.g. lean vs. thorough).
Contract signed, 30-50% up front. Weekly demo, shared Slack / Teams, progress transparent in a public backlog.
Clean code, README, deploy runbook. 2 weeks of free support after delivery. Your team owns everything — no lock-in.
6+ years shipping ASP.NET / Blazor / EF Core to production. I've seen what breaks under load, what ages badly, and what pays off. I bring that experience directly to your codebase.
Based in Yaoundé. Full working-hours overlap with Paris, London, Berlin. Async-friendly for US teams (I keep late hours for US Eastern standups). No coordination pain.
Native French, fluent English. I write proposals, docs and PR descriptions in whichever your team runs on — clear enough for a non-technical stakeholder to follow.
Yaoundé, Cameroon (GMT+1 year-round, no DST). I overlap fully with European working hours, and I flex late for US Eastern standups. For West-Coast US, we run async — daily written updates, Loom videos, weekly synchronous review.
Wire transfer (SEPA for EU), Wise, or Payoneer. Invoices in EUR, USD or GBP. Standard payment terms 15 days net. Upfront deposit of 30-50% depending on scope. All standard, no exotic setup on your side.
You do, fully. IP transfer clause in every contract. Code lives in your repo from day one — I push directly to a branch you own. No lock-in on tooling, no proprietary framework.
Yes — happy to sign under your agency's brand, communicate via your PM, invoice your entity. Won't approach your client directly, ever.
I also work with Laravel, Vue.js, and Python — but I only take those on when there's a real fit. If you have a JS-heavy project and I don't add specific value, I'll tell you and refer someone who does.
Previous clients on request — most are French-speaking African startups and internal enterprise tools where public case studies aren't possible. I'm actively building a public portfolio of international engagements — early clients get transparent pricing in exchange.
Book a 30-minute call — no obligation. Worst case, you leave with a clearer picture of your build.
