About Okafor Martins Chinwike

Staff Software Engineer at National Grid UK

I’m a Staff Software Engineer with over a decade of experience building scalable, user-focused web applications, currently contributing to high-impact systems at National Grid. My background combines a strong foundation in Mathematics and Computer Science with an MBA, which shapes how I approach both technical execution and strategic decision-making.

Beyond engineering, I’m deeply passionate about mentoring. I’ve been doing it for many years, and it’s one of the most fulfilling parts of my journey. Nothing compares to seeing someone grow in confidence, move from confusion to clarity, and eventually start solving problems independently. That transformation is what drives me.

On ADPList, I focus on helping engineers at different stages - whether you're just getting started, transitioning into tech, or aiming to level up into senior or staff roles. I can support with:

Breaking down complex frontend concepts (React, Next.js, TypeScript) Career growth strategies and navigating promotions System design thinking for frontend engineers Code reviews and best practices Building confidence and clarity in your learning path

My mentoring style is practical, honest, and tailored.

Sessions with Okafor Martins Chinwike

• Frontend Career Advice (45 min): Whether you're stuck at junior level, unsure how to level up, or trying to specialise in the right area - this session is for you. As a Staff Frontend Engineer working with React, Next.js, and TypeScript in a FTSE 100 company, I'll give you honest, practical advice on what engineering teams actually look for, how to grow your skills strategically, and how to position yourself for the role you want next.
• Breaking Into Software Engineering (45 min): You've been learning to code, but breaking into your first engineering role feels overwhelming. In this session, we'll cut through the noise and focus on what actually matters: building a portfolio that gets noticed, positioning yourself effectively on your CV, and navigating the job search with a clear strategy. Whether you're self-taught, a bootcamp grad, or a recent CS graduate, you'll leave with a concrete next step.
• Mock Technical Interview - React & JavaScript (45 min): Nothing prepares you for a technical interview like doing one. In this session, I'll run a realistic mock interview covering JavaScript fundamentals and React concepts - the kind of questions you'll face at junior to mid-level. You'll get honest, structured feedback on both your technical answers and how you communicate under pressure. Come ready to be challenged; leave knowing exactly where to focus your prep.
• Making the Jump: Mid-Level to Senior Engineer (45 min): Technically competent but not getting promoted - or not landing senior roles in interviews? The gap between mid and senior isn't just about writing better code. It's about owning problems end-to-end, influencing technical decisions, and being someone the team relies on. As a Staff Engineer who's navigated that journey, I'll help you identify what's actually holding you back, how to demonstrate senior-level thinking in your current role, and how to position yourself convincingly in interviews. Come with your specific situation - we'll make a plan.
