…A Curious Kid with a Passion for Technology

For Onyedikachi Ugwu, technology has always been more than just a career, it’s been a lifelong passion. As a child, he had an insatiable curiosity about how things worked. “I was that kid who took apart broken radios, fans, and electronics, sometimes without knowing how to put them back together,” he laughs. His parents quickly realised he had a knack for problem-solving and encouraged him to pursue technology instead of following in his father’s footsteps as an accountant.

“My original plan was to study accounting like my dad, but looking back, I’m so grateful they nudged me in a different direction.” To build on his interest, his parents sent him to a science-focused secondary school, where he thrived. While waiting for university admission, his mother enrolled him in a computer and phone repair training programme, a hands-on experience that turned his curiosity into real skills. “That was a game-changer for me. I wasn’t just learning theory; I was actually fixing things, troubleshooting software, and figuring out how different systems worked. From there, my curiosity only grew.”

Onyedikachi’s tech career officially kicked off with an internship at CWG, where he got his first taste of IT support, troubleshooting, and application development. “That internship opened my eyes to how big the tech industry really is. I loved every bit of it.” His skills and work ethic earned him a full-time position, and soon he was working on major projects for top financial institutions like UBA, FBN, and FCMB.

“Working with banks was fast-paced and intense. Every day came with new challenges, system upgrades, troubleshooting critical issues, and keeping operations running smoothly. That environment pushed me to think on my feet and sharpen my technical skills.”

Later, at Longbridge Tech, his focus shifted even more toward cybersecurity. “Banks deal with huge amounts of sensitive data, and security is a constant concern. I realised I didn’t just want to develop core banking apps, I wanted to protect them from ever being compromised in the first place.”

That realisation led him to pursue a master’s degree in cybersecurity in the UK. “Moving to the UK wasn’t easy, but it was one of the best decisions I’ve made. I was exposed to cutting-edge cybersecurity tools, advanced security frameworks, and a whole new way of thinking about threat detection and incident response.”

“The biggest difference? Work culture,” Onyedikachi says. “In the UK, there’s a real focus on work-life balance, flexible working policies, and mental well-being. Also, collaboration is huge, teams work together across different areas, and there’s a culture of continuous learning through certifications, research, and conferences.”

That’s not to say Nigeria’s tech scene isn’t thriving. “Nigeria’s tech space is full of innovation. The start-up scene is booming, and there’s a real sense of community among tech professionals. But there are challenges like limited infrastructure, inconsistent internet access, and a general lack of cybersecurity awareness.” Despite the hurdles, he sees massive potential. “Nigeria’s tech industry is still developing, but the drive and talent are undeniable.”

Cybersecurity wasn’t Onyedikachi’s first choice. “I started in IT support and application development, but the more I saw how easily vulnerabilities could be exploited, the more I wanted to do something about it.”
What excites him most about cybersecurity? “It’s never boring! Cyber threats evolve constantly, and defenders have to stay ahead of attackers. It’s like solving a puzzle that’s always changing, and that keeps me on my toes.”

But for him, it’s about more than just tech. “At the end of the day, cybersecurity is about protecting people, businesses, and even entire economies. Knowing that my work prevents fraud, data leaks, and cyberattacks gives me a real sense of purpose.”

The Biggest Cybersecurity Threats Right Now
Right now, Onyedikachi sees ransomware, phishing, and insider threats as some of the biggest challenges. “Ransomware attacks have become more sophisticated, attackers don’t just lock your data; they threaten to leak it if you don’t pay up. Phishing is evolving too, with scammers using smishing (SMS phishing) and vishing (voice phishing) to trick people.”

Insider threats are another growing concern. “Sometimes, it’s malicious employees, but often, it’s just human error. People click on the wrong link, use weak passwords, or fall for scams. And with remote work becoming the norm, personal device security is more important than ever.”

Fighting Cybercrime on the Frontlines
One of his toughest challenges? Stopping a phishing attack on a financial institution. “Hackers were impersonating executives and sending fake emails to employees, trying to steal sensitive data. We had to act fast to identify compromised accounts, contain the attack, and secure the system.”

Beyond just stopping the attack, his team took long-term action. “We launched a company-wide phishing awareness campaign, strengthened multi-factor authentication, and improved email filtering. That experience showed me how important education and proactive security measures are.”

So how does he keep up with this ever-changing field? “I follow industry blogs like Threatpost and KrebsOnSecurity, attend webinars, and go to conferences like BSides London. Being part of online cybersecurity communities helps too. But hands-on learning is key, doing projects, testing tools, and getting certifications keeps me sharp.”

A Common Misconception About Cybersecurity
One of the biggest myths? “People think cybersecurity is all about firewalls and antivirus software. But the truth is, it’s just as much about people and processes. Human error is often the weakest link, so security training and awareness are just as critical as having the right tools.”

For Nigerians looking to break into global tech, his advice is simple: “Keep learning. Get certifications in high-demand fields like cybersecurity, AI, and cloud computing. Join online communities, contribute to open-source projects, and build a strong portfolio. And don’t be afraid to apply for jobs, many companies value diverse perspectives.”

Looking ahead, he sees AI changing the game. “AI will make cybersecurity more proactive, better threat detection, faster response times. But cybercriminals will use AI too, so human expertise will always be crucial for handling complex threats.”

Beyond his job, Onyedikachi is passionate about mentoring. He’s involved in a government-backed ‘Catch Them Young’ initiative that introduces secondary school students to tech. “We’re in the final planning stages, and I’m excited. The goal is to spark interest in technology at an early age.”
He’s also working on an NGO to support victims of cybercrime. “Cyber fraud ruins lives, and there aren’t enough resources to help victims. I want to bridge that gap and create a world where people feel safe in their digital lives.”

For now, his focus is on expanding the ‘Catch Them Young’ programme and strengthening cybercrime victim support. Long-term, he hopes to contribute to global cybersecurity efforts while continuing to mentor and inspire the next generation of tech professionals.

Onyedikachi’s journey – from a kid fixing broken radios to a cybersecurity expert making a real impact. This is a proof that passion, persistence, and lifelong learning can take you anywhere. His story is an inspiration to aspiring tech professionals, especially those from Nigeria looking to make their mark on the global stage.
