An Interview with Android Engineer and AI Security Researcher Ivan Mishchenko
As artificial intelligence becomes deeply embedded in mobile applications, the role of engineering judgment is changing. Today, building AI-powered mobile products is no longer only about innovation speed or model accuracy. It is increasingly about responsibility, security, and the ability to translate experimental ideas into production-ready systems.
Hackathons have become an early reflection of this shift. Once focused primarily on rapid prototyping, they now function as testing grounds for applied AI, mobile security practices, and engineering maturity. In this environment, technical jury members play a critical role in shaping how emerging products are evaluated and refined.
Ivan Mishchenko, a Senior Android Engineer, AI security researcher, and recipient of the Digital Leaders Award 2025 (Developer of the Year – Artificial Intelligence), has served as a jury member at multiple international technology events, including the NextGen Hackathon (December 2025) and Armenia Digital Awards (November 2025). His expertise lies at the intersection of Android development, artificial intelligence, and mobile application security.
We spoke with Ivan about his role as a hackathon judge, the challenges of evaluating AI-driven mobile projects, and how real-world banking experience influences his approach to innovation and security.
Ivan, what was the primary focus of the NextGen Hackathon you judged?
The NextGen Hackathon focused on building practical digital products that integrate artificial intelligence in a meaningful way. A significant portion of the submissions were mobile-first applications, which immediately raises questions about privacy, data protection, and secure AI integration.
From the jury’s perspective, the challenge was not to reward novelty alone, but to assess whether AI genuinely improved the product and whether the solution could realistically evolve beyond a demo. This included evaluating how teams handled user data, how AI models were deployed, and whether the overall system demonstrated engineering discipline.
What criteria did you personally prioritize when evaluating mobile AI projects?
My evaluation framework was built around several core dimensions:
1. System Architecture
I paid close attention to how teams structured their applications. Even in hackathon conditions, architectural decisions matter. Clear separation of concerns, modular design, and scalability indicate whether a project can survive real-world growth.
2. Security by Design
Security was a central focus. Mobile applications often handle sensitive personal or financial data, and AI components introduce additional attack surfaces. I evaluated authentication flows, data storage practices, encryption usage, and awareness of AI-specific risks such as data leakage or model misuse.
3. Quality of AI Integration
I looked at whether AI was used appropriately for the problem domain. Strong projects demonstrated a clear understanding of why AI was needed, how inference was performed (on-device or cloud-based), and how the system behaved when models failed or returned uncertain results.
4. Engineering Maturity
Clean APIs, understandable logic, and realistic trade-offs matter even in early prototypes. Teams that demonstrated disciplined engineering consistently stood out.
From hackathon evaluation to production banking systems
One factor that strongly shaped my approach as a jury member is my direct experience implementing similar AI-driven security solutions in production banking environments.
I have worked on mobile banking applications in Georgia, including projects for Space Bank, where security, reliability, and regulatory compliance are non-negotiable requirements. In these environments, architectural mistakes or insecure design decisions can lead to financial loss, regulatory violations, or reputational damage.
In my professional work, I have been involved in:
- Designing secure Android architectures for financial applications
- Implementing biometric authentication flows with fallback mechanisms
- Applying AI-assisted fraud detection logic based on user behavior analysis
- Ensuring secure data storage, encryption, and controlled access to sensitive resources
This experience directly influenced how I evaluated hackathon projects. I assessed not only whether an idea worked in a demo, but whether it could realistically transition into a regulated, high-risk environment such as banking or fintech.
How did this real-world experience affect your feedback to teams?
One of the most valuable roles of an experienced judge is translating industry-grade constraints into guidance that early-stage teams can apply immediately.
When reviewing projects, I often referenced real-world challenges encountered in banking systems:
- regulatory expectations around data protection
- limitations of mobile hardware and battery usage
- threat models involving compromised devices or network interception
By grounding feedback in these realities, teams were encouraged to rethink their solutions not merely as prototypes, but as potential future products. In several cases, teams adjusted their architectures during the hackathon itself by introducing on-device inference, improving authentication flows, or separating AI decision-making from UI logic.
What common issues did you observe in AI-powered mobile projects?
A recurring issue was over-reliance on external AI services without sufficient consideration for data security. Some teams transmitted sensitive user data to third-party APIs without anonymization or clear safeguards.
Another common challenge was misunderstanding the limitations of on-device AI. While on-device models improve privacy and latency, they require careful optimization and realistic expectations. I often suggested hybrid architectures that combine local inference with secure backend validation.
The strongest teams treated security as a design constraint rather than an obstacle. This mindset consistently led to more robust and credible solutions.
How does your research background influence your role as a judge?
My research focuses on AI-assisted security in Android applications, including phishing detection, biometric authentication, anomaly detection, and on-device machine learning. I have published peer-reviewed articles on these topics and presented research at international conferences.
Because of this background, I naturally evaluate products through a threat-oriented lens:
- How could this system be abused?
- What assumptions does it make about user behavior or device integrity?
- How would it behave under adversarial conditions?
At the same time, I aim to balance academic rigor with practical guidance. Hackathons are about creativity and momentum, and my role is to help teams align innovation with realistic engineering expectations.
Developing a security-first framework for evaluating mobile AI
Through research, production work, and jury participation, I have developed a consistent framework for evaluating AI-powered mobile applications.
This framework combines:
- mobile security principles
- AI risk assessment
- architectural scalability considerations
Rather than treating AI as an isolated feature, I evaluate it as part of a broader system that includes authentication, data storage, networking, and user interaction. This system-level perspective is still relatively uncommon in early-stage development environments, where AI is often judged primarily by accuracy metrics or novelty.
My contribution lies in introducing security-first, system-level thinking into AI product evaluation for mobile platforms, where constraints and risks differ significantly from web or cloud-only systems.
International recognition and professional trust
My invitations to serve as a jury member at events such as the NextGen Hackathon and Armenia Digital Awards reflect growing international recognition of my expertise in mobile AI security.
These roles involved direct responsibility for evaluating the work of competing teams, assessing technical quality, security posture, and innovation potential. Combined with international awards such as:
- Digital Leaders Award 2025 (Developer of the Year – Artificial Intelligence)
- Cases & Faces Award (AI & Machine Learning, USA)
they demonstrate sustained professional recognition across multiple countries and industry contexts.
Why jury participation matters for senior engineers
Serving as a judge is both a responsibility and a form of professional contribution. It allows experienced engineers to:
- influence emerging technical standards
- mentor early-stage teams
- identify recurring industry risks at an early stage
For me, jury work reinforces the idea that engineering leadership extends beyond writing code. It includes evaluation, mentorship, and shaping the broader technology ecosystem.
Advice for teams building AI-powered mobile applications
There are three principles I consistently emphasize:
**Security is a feature, not an afterthought Users may not immediately notice good security, but they will notice its absence.
**AI should augment, not obscure If a team cannot explain what a model does and why it is needed, it is likely being applied too early or incorrectly.
**Engineer for reality, not demos Edge cases, failures, and misuse scenarios are where professional products are defined.
Looking ahead: responsible AI as a competitive advantage
As artificial intelligence becomes a standard component of mobile applications, long-term success will depend on trust, security, and responsible engineering.
My work — across banking systems, academic research, and international hackathon juries — is driven by the same goal: ensuring that innovation does not outpace reliability and user trust. The most successful AI-powered products of the future will be built by engineers who understand both technical capability and responsibility.
Participating as a jury member is one way I contribute to shaping that future by helping emerging teams align creativity with real-world standards.
