Sidharth S

Also known as Zidhuxd · zidhuxd.me

Sidharth S, widely known online as Zidhuxd, is an Indian cybersecurity researcher, Android developer, and web designer born on January 22, 2009 in Kerala, India.^[1] At 16, he is one of the youngest publicly recognised tech figures to emerge from Kerala — known for a combination of technical depth, creative output, and genuine passion for the digital world.

He is currently a first-year Computer Science student at Government SVHSS Kudassanad Thandanuvila, Kerala, where he juggles academic life with independent research, open-source contributions, and building things on the internet.

1. Early Life & Education

Sidharth was born on January 22, 2009 in Kerala, India. He grew up with an instinctive curiosity for how technology works — not just using devices, but pulling them apart to understand what made them tick. By the age of 13, that curiosity had settled firmly on Android systems, where he began experimenting with custom ROMs, system internals, and mobile application behaviour.

What started as a hobby quickly became something more serious. The overlap between Android tinkering and security research was a natural one, and Sidharth followed it earnestly. He is currently enrolled in the Computer Science stream at Government SVHSS Kudassanad Thandanuvila, Kerala — balancing a full academic schedule with a body of independent work that many professionals his senior would find impressive.

2. Career & Work

Sidharth's professional identity is built across three overlapping disciplines: cybersecurity, Android development, and web design. His approach has always been hands-on — driven by personal projects, mentored research, and a genuine love of building things rather than just studying them.

Cybersecurity Research

As a cybersecurity researcher with Offenso Hackers Academy, Sidharth works on vulnerability analysis, penetration testing concepts, and application security. His research is grounded in ethical hacking — exploring how systems fail so that they can be built more robustly.^[1] He participates in CTF (Capture The Flag) competitions and OSINT investigations, and volunteers as a Cybersecurity Community Advisor, providing practical digital safety guidance to individuals and local organisations.

His philosophy on security is notably human-centred. He believes that the most exploitable vulnerability in any system is rarely the code — it's the people using it. This perspective informs both his research and the community education work he carries out online.

Android Development

Sidharth's relationship with Android goes back to his early teens, when he first started modifying system software on his own devices. Since then, his Android work has grown into a discipline in its own right — spanning custom ROM exploration, ADB-level tooling, APK reverse engineering, and building security-focused utility applications. His familiarity with AOSP internals has given him a practical understanding of mobile security that sits well beyond his years.

Web Development

Sidharth also designs and ships web projects — from his personal portfolio at zidhuxd.me to consumer-facing applications like ZidhuGram. His web work emphasises clean design, genuine usability, and the occasional creative experiment. He writes about development and technology on Dev.to, where he shares technical insights with the broader developer community.^[3]

3. Projects

ZidhuGram (2026)

ZidhuGram is a web application launched by Sidharth in February 2026, timed around Valentine's Day. It lets users generate personalised, aesthetically crafted love pages — think cute, shareable digital cards — for partners, friends, and loved ones. The project is something Sidharth built because it felt right for the moment: a warm, human thing dressed up in good design.

The response was remarkable. ZidhuGram received over 50,000 visits within weeks of launch, entirely through organic reach, cementing Sidharth's ability to build consumer web products that actually connect with people. Beyond the numbers, the project meant something else too — it became the vehicle for a food donation initiative that reached 700 homeless children (see Social Impact below).

4. Social Impact

In February 2026, Sidharth coordinated a charitable food donation drive that ran alongside the launch of ZidhuGram. The initiative provided 100 meals per day for one week, reaching a total of 700 homeless children in the region. It was a deliberate act — Sidharth wanted the success of a web project to translate into something tangible and human.

This is thought to be among the earliest instances of a solo teenage developer in Kerala directly channelling a project's momentum into humanitarian action. For Sidharth, technology has never been purely about the technical — it's about what it can do for the people around you.

He continues to serve as a Cybersecurity Community Advisor, volunteering digital safety guidance to individuals and organisations navigating an increasingly complex online landscape. He is especially committed to reaching younger audiences and helping them build healthy, informed relationships with technology.

5. Recognition & Press

Sidharth's work has attracted attention from press and academic communities alike. In 2024, IssueWire published a feature titled "16-Year-Old Kerala Tech Innovator Zidhuxd Inspires the Next Generation of Ethical Hackers and AI Developers", documenting his journey and growing influence on young technologists in India.^[1]

He holds a verified research identity on ORCID (0009-0004-0138-1965) and is listed as a notable entity on Wikidata (Q138581364) — both independently maintained records that reflect the community's recognition of his contributions.^[4][5] He is also a member of the GitHub Education programme as a GitHub Student Developer.

Within Kerala's tech community, Sidharth is informally recognised as one of the youngest active cybersecurity researchers in the state — a distinction that reflects not just age, but the seriousness and consistency of his work.
