As a seasoned engineer with over five years in complex software systems across multiple industries (such as Logistics systems, HealthTech, EdTech, among others), I bridge the gap between complex technical challenges and accessible solutions. My expertise in cloud-based applications isn't just about writing code, it's about making technology work for people.
Whether you're struggling with debugging code, designing efficient algorithms, or navigating complex system architectures, I've been in your shoes. I've developed enterprise applications from the ground up and guided hundreds of learners through challenges ranging from basic syntax errors to advanced architectural decisions.
**What sets me apart? I don't just solve problems, I help you understand them. My approach combines hands-on engineering experience with a talent for explaining complex concepts in straightforward terms. From untangling complex code issues to optimizing system performance, I translate technical challenges into clear, actionable steps**.
My greatest achievement isn't the systems I've built, it's watching my mentees transform from curious beginners to confident professionals. This journey has sharpened my ability to meet you exactly where you are—whether you need an expert to help resolve a persistent bug or a patient guide through new programming paradigms.
**Let me help you turn technical obstacles into opportunities for growth.**
With years of experience in finance, web3, and education, i specialize in developing cloud-based applications. I've led key roles in large projects, optimizing processes, server managements, and system performance for efficiency. My dynamic problem-solving approach drives creative solutions, always staying updated with the latest technical breakthroughs to enhance my skills.
Daniel Uche is a senior Full Stack software engineer with great skills.
I live and breathe code, as a software craftsman, I craft code that scales for web and mobile. I have built applications that serve millions of user traffic.
Feel free to hit me up on any problem you might have across
**React**, **Redux**, **Node**, **JavaScript**, **Mobile app**,
**Software Architecture**, **Software Engineering**, **Database Design**. I can help make complex concepts look simple.
I can also help with your Software Analysis project using **LLVM Compiler Infrastructure**
Also I am familiar with CI/CD, container container orchestration and elastic search and logstash ecosystem.
I teach Operating Systems and functional programming fundamentals to CS students and guide fellow professionals through legacy codebase maintenance, practical software architecture, and new language/framework learning skills.
For students, I offer two types of sessions - one is a lecture-style session where I can go over course notes/slides on a particular topics and offer additional explanations and examples to improve your understanding of the material. Another type is an assignment take-up session where I can go over a past assignment and guide you through steps to solving it.
For working professionals, I offer the following options:
* Focused problem-solving sessions - if you have a particular issue that you're stuck with in a project you're working on, I can pair with you over Zoom screen-sharing
* Code review - if you cannot understand how to work with part of your codebase or if you'd like a second opinion on work that you've just completed, I can pair with you over Zoom and do a live code review and/or prepare ahead of time and go over my findings on a call
* Long-term mentorship - if you would like to learn some more fundamental skills or pick up a framework/design pattern/best practices, I can develop a custom-tailored learning plan that fits your skill level and schedule and offer regular teaching sessions with optional take-home exercises
A bit about me
---
I am a tech founder and a senior polyglot/full-stack developer, with a passion for teaching and mentorship. In a bit of spare time from my work, I am looking to help fellow software developers get more comfortable with our craft and exercise my teaching skills while I'm at it.
So far, I've done a wide range of work - web app front-end and back-end, data pipelines at scale, DevOps/infrastructure, mobile (quite a bit of iOS and previously some Android) and some security. I have a reasonable taste for UI design and user experience, despite that not being my primary specialization.
The industries I've worked in so far were heavily concentrated around finance/banking/FinTech and GovTech, although I've also been a founding developer at a couple of B2C startups and learned a lot throughout that experience.
My personal research interests include operating systems and programming language theory.
As cliche as it sounds, I try to learn something new all the time and I consider this of vital importance to my professional skillset. I always prioritize systems understanding and learning how to learn over memorizing APIs - and it's a philosophy that I try to share with my students as well.
Teamwork and constant exchange of expertise with my peers is a close second most important value to me. A software product can be almost meaningless without a team that welcomes learning from failures, encourages curiosity and fosters true human friendships, and empathy both towards each other and towards the customers of the software we create.
New client intake process
---
1. Intro/triage call [free of charge] [15 min] - this is a Zoom video call where I try to understand your background, the problem you're looking to solve and whether I believe we'd be a good fit for a productive mentor/mentee relationship.
2. Supplemental terms acceptance - as an independent contractor and not an employee of Arc, I ask my clients to accept a few additional terms that make session time measurement, scheduling and work product acceptance more precise, and further clarify the extent of our mentorship relationship.
3. Creation of Freelance Job/Scheduled Session on Codementor - if you haven't done that yet, I will ask you to create and assign me a freelance job and/or a scheduled session with a precise description of the topics we would be covering.
For certain sessions, preliminary preparation may be required - if that is the case, we would discuss the details and estimated time ahead of time and a Freelance Job would be required to cover the effort of the preparation.
Availability
---
Please take a look at my Codementor calendar to plan intro calls and sessions. Generally, I am available between 3:30pm and 8pm Eastern Time (New York/Toronto), Monday to Saturday, but I try to schedule all of my teaching engagements between 6pm and 8pm whenever possible.
*IMPORTANT: Urgent sessions are unfortunately not available at this time.* I am currently working through Codementor as a mentor, and unable to work as an on-call freelance developer.
Please also note that I cannot provide consultations over chat - in my experience, it's generally more time-consuming for everyone, and copy-pasting code over chat can get messy. For those reasons, I only work through Zoom video calls with screen sharing.
If you have any questions about the process or would like to book a call, I am happy to chat on Codementor - I should be usually available Monday-Saturday, 1pm - 8pm Eastern Time, subject to my other engagements. While I try to respond as soon as I can, I may take up to one business day or longer depending on how busy my schedule might get.
