Security Engineer | Penetration Testing | Bot Mitigation | Incident Response | Application Security
I work as a Senior Security Engineer where I deal with large scale security challenges daily, from bot networks and web abuse to vulnerability assessments and incident response on platforms serving millions of users.
My background covers the full security lifecycle:
Offensive security
Vulnerability assessment and penetration testing across web applications, identifying weaknesses before attackers do. Experience with VAPT engagements covering OWASP Top 10, authentication flaws, injection vulnerabilities, and business logic issues.
Defensive security
Bot mitigation, web abuse detection, WAF configuration, rate limiting, and traffic analysis. I have dealt with everything from credential stuffing and account takeover attempts to large scale scraping operations and store cloning attacks.
Risk and compliance
Threat modeling, architecture risk assessments, and security reviews helping businesses understand their attack surface and prioritise what to fix first.
Incident response
Investigating active breaches, tracing attack vectors, containing damage, and hardening systems post incident so it does not happen again.
Some specific problems I help businesses solve:
Unauthorised account access and breach investigations, bot traffic and automated scraping, fraudulent analytics inflation, store cloning and product theft, credential stuffing, checkout abuse, WAF setup and tuning, and ongoing security monitoring.
My approach is practical not theoretical. I start by understanding exactly what is happening before recommending anything. Whether that is analysing traffic patterns, reviewing access logs, or running a proper vulnerability assessment the goal is always targeted solutions that fix the real problem.

I find vulnerabilities in web apps, APIs, networks, AI/LLM and cloud systems - and I fix them. If you have a security problem, there's a good chance I've already solved something like it.
Check what I've done at thesecurelancer[.]com.
4 things I do on primary:
Penetration Testing: Web apps, APIs, networks, cloud, and AI systems. Real manual testing, not scan dumps. Every finding comes with a proof of concept, CVSS score, and a fix your dev team can actually use.
Cloudflare Setup: WAF, DDoS protection, SSL/TLS, bot filtering, custom rules. The configs that block real attacks, not just the defaults.
Malware Removal: Backdoor removal, injected scripts, blacklist cleanup (Google, McAfee, Sucuri), root cause fixed so it doesn't come back.
Ongoing Hardening: Monitoring, patch management, monthly reports.
Currently Security Engineer at Monotype, a global enterprise SaaS company, doing this daily. Previous freelance engagements include a US hospital network, an ERP platform, and an e-commerce platform, all under NDA.
Tools: Burp Suite Pro, Metasploit, Nessus, OWASP ZAP, Checkmarx, SonarQube, sqlmap, Cloudflare WAF
Only work on systems you own or are authorized to test. Questions before hiring, just message me.
