Full story

My journey into cybersecurity began in 2015 when my then-employer requested employees to unearth potential vulnerabilities in our SaaS platform. Despite having no prior exposure to hacking methods, I dived into the challenge and within just two days, found myself captivated by the intricate world of cybersecurity. Although my findings were minor, the experience sparked a fascination that grew over time.Fast forward to four years later, I joined our sister company, initially as a project manager. My growing interest in cybersecurity eventually led me to the role of the Information Security Officer. Over the next two years, I maintained the ISMS, led the vulnerability program and successfully prepared for and passed the ISO 27001 audits annually.Simultaneously, my curiosity in NoCode development began to peak. As a freelance consultant, I helped transform ideas into reality using NoCode tools. My role shifted within the company when I discovered a dozen critical vulnerabilities in the platform I was using. For the next six months, I worked with the team to address these issues. However, my journey was cut short when the company changed its focus and didn't allocate enough resources to address all security concerns.This abrupt end, while unfortunate, didn't hinder my enthusiasm for cybersecurity. Instead, it propelled me into a period of intensive self-learning. I consumed as much content as I could on offensive security, diving into books, online courses, CTFs, and bug bounties. I soon found myself armed with extensive knowledge that needed an outlet, leading me to public vulnerability disclosure programs.My knowledge of these platforms and my unique perspective from varied work experience helped me identify potential threat models and possible attack vectors swiftly. I was particularly successful in business logic, which led me to focus on IDORs and Mass Assignments. Even though I started with low hanging fruit, I eventually found several critical vulnerabilities, including ones within a company handling billions of euros.Unfortunately, my reward was just a €50 gift voucher, but I didn't let this dampen my spirit. I worked closely with their lead developer and managing director, explaining vulnerabilities, re-testing fixes, and ultimately, encouraging them to pursue a professional pentest and code review.Today, my interest in cybersecurity is as vibrant as ever. With a finely-tuned intuition for detecting vulnerabilities, I often explore the apps I use daily. I've submitted over 30 reports across multiple platforms but for the satisfaction and learning I gain from each discovery.

Full story

From an early age, I've always been brimming with ideas. I distinctly remember designing an automatic pill dispenser box at the age of only 12, which is just one instance of my innate drive to dissect complex problems and find innovative solutions. Sometimes, I'd lose myself for days, weeks even, in the pursuit of solving a single problem - a passion that has often led me on unexpected, yet enriching journeys.As my career in technology evolved, so did the scope of my ideas. With experience in design and product development, I could transform these ideas into detailed mockups and specifications. However, the missing piece of the puzzle was the ability to bring these ideas to life independently, without the need for a developer, which remained unattainable until 2018.The emergence of NoCode tools changed everything for me. Tools like Bubble gave me the ability to build complex web apps, bringing me closer to my goal. Empowered by these resources, I embarked on numerous projects simultaneously, a decision that, while initially overwhelming, taught me invaluable lessons about the complexities of software development.After this rapid-fire experience, I chose a more methodical approach, working on a few ideas at a time and successfully launching several projects. Some of these even reached #1 on Product Hunt, providing me with invaluable lessons on product lifecycle and user engagement.Feeling confident in my abilities, I decided to lend my expertise to others and started consulting. My tool of choice was Adalo, where I became one of the first listed experts. It was exhilarating to take ideas and turn them into realities singlehandedly, feeling as though I'd unleashed superpowers. However, freelancing presented its own challenges, namely managing client expectations and working solo.An opportunity with Adalo changed this, as I accepted a role as a Customer Advocate. This role was a perfect blend of my prior tech roles and my NoCode development skills. I derived immense satisfaction from aiding customers in realizing their dream projects.However, my growing interest in cybersecurity soon intersected with my role at Adalo. I discovered some critical security issues within our platform and dedicated several months to resolving these. Sadly, the direction of the company changed, and my role was eliminated. The end of my NoCode journey was heartbreaking and took a toll on my passion for NoCode development.But every end is a new beginning. This experience paved the way for my growing passion in cybersecurity - a story you can continue reading in the next section of my site!

Full story

Much like many others in the tech industry, I have been captivated by the promise of AI. Whether it's a bubble waiting to burst or the dawn of a new technological era, there's no denying that AI has already significantly improved many aspects of our lives. My guiding principle in engaging with AI is to use it to understand an answer, rather than to just get an answer. Not just as a means to an end but as a way to uncover the process leading to that end.Back in 2020, I first explored the possibilities offered by GPT3. Even then, the results were impressive, but my focus was entrenched in the new and exciting NoCode movement, which meant AI took a backseat. My interest in AI was truly reignited with the launch of DALLE 2, swiftly followed by Midjourney's hyper-realistic image generation capabilities and the jaw-dropping launch of ChatGPT. In the subsequent months, the tech landscape was transformed with a flurry of new use cases and technologies that for the first time, it felt as though I could not keep up with the speed at which technology was accelerating.Like many others, I not only used AI as an alternative to traditional search engines but also found ways to use it to enhance my work. Rather than relying on AI to perform tasks for me, I engaged with it as a tool to refine my processes, not asking for it to "do it for me" but more in a "how can I do this better" way. I don't believe AI is at a point to replace a human in most professional aspects, the technology is not reliable enough at this moment (June 2023) but as an assistive technology, it cannot be beaten.An ongoing project that I'm proud of involves creating a chat group of AI personas, each representing a different role within a company, like a marketer, developer, or product manager. I've devised a system where these AI personas can interact with each other in a chat-like environment (Discord). This setup proves incredibly useful in fleshing out the basics of a project, interpolating the potential requirements from each persona and determining the optimal approach for each aspect of the project. The project is currently on hold while I work on improvements and in the interim, I've observed similar initiatives take root, each offering a unique spin on the shared goal of using AI to recursively evaluate, question, and respond until a satisfactory resolution is reached.Currently, one of the significant advantages I hold is my comprehensive understanding of the existing AI systems and tools. I know how to interlink various platforms to achieve a desired result. Paired with my methodical approach to prompting, I believe this knowledge equips me to deliver high-quality, reliable outputs that exceed the results possible with a superficial understanding of these tools. Being familiar with the strengths and weaknesses of these AI systems enables me to tailor my approach, adjust my expectations, and adapt my strategies, ensuring I consistently obtain the most accurate and useful outcomes.Ultimately, the knowledge and skills I've cultivated over the past nine months are rapidly becoming essential for future workforces. As AI continues to evolve, it's clear that adaptability, an understanding of AI technologies, and the ability to integrate these tools into workflows will be vital for staying ahead. We're standing on the brink of a revolution in the way we work, with AI at the helm. Those who can leverage AI to its full potential will not only remain relevant but will be instrumental in shaping the course of this exciting new era.
