Professional Profile
Fidelis Uwem Joseph
I help growth-stage companies and enterprises ship reliable software across mobile, web, backend, and cloud. I close the gap between engineering complexity and business outcomes.
What I Deliver¶
-
Backend Engineer
I design and build production-grade APIs and server-side platforms that teams can maintain, extend, and trust under load.
- RESTful and event-driven APIs built with Django, FastAPI, Laravel, SlimPHP, Spring Boot
- Modular architecture patterns — clean separation of concerns, testable codebases
- Enterprise security: auth flows, role-based access, secrets management
- Systems designed to support team scale, not just traffic scale
-
Mobile Engineer
I deliver cross-platform mobile applications that perform on both Android and iOS without sacrificing native quality.
- Production apps built with Flutter and React Native
- Shared business logic via Kotlin Multiplatform — one codebase, two platforms
- Native Android UI with Jetpack Compose, custom native modules where needed
- Architectures that integrate cleanly with backend domain models and evolving APIs
-
Automations Engineer
I eliminate operational bottlenecks by automating workflows and integrating your systems — reducing manual overhead and human error at scale.
- Multi-step pipelines with N8N, Make.com, Zapier, and Google Apps Script
- Python-based tools for API orchestration, browser automation, and custom integrations
- Airtable-driven data workflows and automated document generation
- Solutions built to be auditable, maintainable, and resilient in production

Client Testimonials¶
"I started working with Joseph in the summer of 2024 on a prototype project that needed a ridiculously fast turnaround. It involved Airtable, Glide, and some automations, and I expected it to take about a week. Joseph delivered everything in just two days well ahead of schedule and without any fuss.
After that, I kept bringing him onto other projects and quickly realised just how versatile and adaptable he is. Over time, he's become an invaluable resource, able to take on just about anything even when the requirements are vague. He thrives in ambiguity, works things out quickly, and delivers real, working solutions instead of just ideas.
If you need someone who can turn vague ideas into real, working systems quickly and without hand-holding Joseph is the person you want on your team. Highly recommended."
