Advanced Security Services

I'm like finding vulnerabilities others miss, I focus on the complex security issues hiding in business logic, parsing flaws, architectural decisions, and complex implementation details

Advanced Web Application Testing

My approach goes beyond standard security checklists. I dig deep into how your application actually works, mapping out complex user flows and business processes to find logic flaws that traditional testing misses. I examine how different components interact, where trust assumptions break down, and how parsing differences between systems create exploitable gaps.

When I analyze your web applications, I look beyond the obvious:

Business Logic Exploits

Parsing Differentials

Access Control Bypasses

State Management Flaws

# Going beyond basic checks to find real issues
$ curl -i -H "Content-Type: application/json" \
-H "Authorization: Bearer eyJhbGciOiJub25lIn0..." \
https://api.target.com/admin/users
# Found: JWT algorithm confusion vulnerability
# Discovered: Race condition in checkout
$ python3 race_condition_test.py \
--parallel-requests 20 \
--endpoint "/api/payment" \
# Result: Balance verification bypass!

$ frida-trace -i "libsqlite*" -U target.app

$ objection --gadget com.target.app explore

[CRITICAL] Secure storage encryption bypassed !

Mobile App Security Deep Dives

I don't just scan your mobile apps—I take them apart. Using advanced runtime manipulation and reverse engineering techniques, I analyze how your app handles sensitive data, implements authentication, and communicates with backend services. This hands-on approach reveals vulnerabilities that checklist-based testing can't find.

My mobile app assessments include:

Runtime Security Bypasses

Crypto Implementation Flaws

Native Code Vulnerabilities

Deep Link Attack Vectors

Blockchain & Smart Contract Security

Blockchain security isn't just about code—it's about economics, game theory, and system design. I analyze smart contracts for subtle edge cases that can lead to significant financial losses. My approach combines automated symbolic execution with manual review to find vulnerabilities that standard audits miss.

When reviewing your blockchain implementations, I focus on:

Economic Attack Vectors

Tokenomics Security

Complex Reentrancy Chains

Oracle Manipulation

// Subtle Flash Loan Vulnerability
contract LiquidityPool {
mapping(address => uint256) private _balances;
function depositTokens(address token, uint256 amount) external {
// CRITICAL: Missing check before state update
_balances[msg.sender] += amount;
// Price oracle call can be manipulated
_updatePriceRatio(); // Exploitable sequence
IERC20(token).transferFrom(msg.sender, address(this), amount);
}
// Needs checks-effects-interactions pattern
}

Code & Architecture Review

Good security starts with good design. I review your code and architecture with a security mindset, looking for subtle issues in how components interact and trust each other. My approach combines static analysis with a deep understanding of secure design patterns to find vulnerabilities that emerge at the system level.

I believe security testing should be collaborative and educational. When I find issues, I don't just report them—I explain how they work, why they matter, and how to fix them properly.

My Security Philosophy

Security isn't about running tools—it's about understanding systems deeply and thinking creatively about how they might break. I spend time learning how your application actually works, mapping complex workflows, and identifying where security assumptions might not hold true. This detailed approach consistently finds critical issues that automated tools miss.

Practical Security Improvements

I focus on providing actionable recommendations that make sense for your specific situation. My reports prioritize issues by actual risk and exploitability, not abstract CVSS scores. I'll help you understand which vulnerabilities need immediate attention and which can be addressed as part of your normal development cycle.

Let's make your applications more secure

I'd love to learn about what you're building and how I can help secure it. Whether you need a comprehensive security assessment or have questions about a specific security concern, let's talk about how we can work together.
