Over this time, I have successfully delivered 660+ projects in 36 countries and built long-term partnerships with companies of all sizes - from early-stage startups to enterprise-level organizations. My clients trust me because I don’t just list vulnerabilities: I make sure they are fixed, retested, and completely closed. This is why I maintain an exceptional ~80% client return rate. I’ve helped organizations in FinTech, e-Commerce, Healthcare, SaaS, Blockchain, and Government industries protect sensitive data, meet compliance requirements, and maintain customer trust. My security assessments have directly prevented breaches, helped companies secure investments, and supported successful audit certifications such as SOC2, HIPAA, and ISO27001 readiness. 🛡️ My Core Expertise I provide a full spectrum of offensive and defensive security services: 🔹 Web Application Penetration Testing Manual and automated testing for vulnerabilities like SQL Injection, Cross-Site Scripting (XSS), Cross-Site Request Forgery (CSRF), Remote Code Execution (RCE), Insecure Direct Object Reference (IDOR), Local/Remote File Inclusion (LFI/RFI), authentication & authorization flaws, business logic vulnerabilities, and misconfigurations. 🔹 Mobile Application Security (Android & iOS) Reverse engineering, static and dynamic analysis, testing data storage protections, API communication security, and exploitation of insecure permissions or misconfigurations. 🔹 Cloud Security Assessments (AWS, Azure, GCP) IAM misconfigurations, insecure storage buckets, weak API protections, Kubernetes & container orchestration security, serverless architecture hardening, and compliance readiness. 🔹 Smart Contract Security Audits (Solidity / EVM) Analysis of reentrancy issues, integer overflow/underflow, unchecked external calls, logic vulnerabilities, and economic flaws that could lead to devastating exploits. 🔹 Infrastructure & Network Penetration Testing External and internal testing for weak services, open ports, privilege escalation, VPN & firewall bypasses, and lateral movement simulation. 🔹 Code Review (SAST/DAST + manual) Deep review of source code to detect insecure coding practices and logic errors before they reach production. 🔹 Incident Response & Forensics Rapid response to active breaches, malware analysis, and post-incident hardening to prevent recurrence. ✅ Results I Deliver - When you work with me, you don’t just get a report - you get tangible outcomes: - Actionable PoCs → Every vulnerability is proven with working exploits, screenshots, and technical detail. - Prioritized Remediation → I rank vulnerabilities by real-world risk and business impact so your team knows what to fix first. - Executive Summaries → Easy-to-understand reports for stakeholders, investors, or compliance auditors. - Free Retesting → After you fix issues, I verify that vulnerabilities are fully patched. - Reduced Risk Exposure → My clients have prevented multi-million-dollar losses by patching critical flaws I discovered. 🏆 Track Record 1. Helped a FinTech startup secure $20M funding by fixing AWS & web flaws pre-SOC2 audit. 2. Discovered and patched critical smart contract bugs before launch. 3. Enabled a healthcare SaaS to pass HIPAA by closing PHI exposures. 4. Cut remediation time by 40% with clear PoCs & prioritized fixes. 5. Prevented severe breaches for an e-commerce platform during peak sales. ⚙️ How I Work 1️⃣ Scope & NDA → goals & rules 2️⃣ Recon → OSINT, surface mapping 3️⃣ Exploitation → manual + automation 4️⃣ Reporting → PoCs + executive summary 5️⃣ Retesting → free verification 6️⃣ Guidance → long-term security 🧰 Tools & Skills Burp Suite, Nmap, Metasploit, Wireshark, OWASP ZAP, custom scripts | OWASP, PTES, MITRE ATT&CK | OSCP, CEH, CompTIA Security+, CISSP-level expertise. ✨ Final Note I don’t just scan - I prove, fix, and retest vulnerabilities until closure. 🚀 Let’s secure your app, cloud, or smart contract today. Send me your scope for a tailored plan within hours. 💬 Cybersecurity Expert Cybersecurity Expert Cybersecurity

EXPERT-VETTED (TOP 1%) | 100% JOB SUCCESS Most AI projects look finished in a demo, then break in production. I build production-grade software. That means it holds up with real users : Scales under real traffic, not just a demo Secure and tested, not "looks fine, ship it" Clean architecture your next hire can build on Costs you can predict before you commit 25 years building software. Now my team and I direct AI agents across the full build and review every line before it ships. Fast, but not vibe coding. I AM A FIT IF YOU Have an idea but no technical leadership to run the build Have a vibe-coded app generating MRR but need a stable foundation under it Started building but need architecture and senior oversight to finish Want to use AI without losing control of your codebase REAL RESULTS A traditional build was quoted at $1.2M. My team and I delivered it for $95K, same scope. Replaced a client's manual spreadsheet process with a web app. Revenue up 71%. Architecture that held through 500% traffic growth 79M pricing calculations a month, in production WHAT WORKING WITH ME LOOKS LIKE Full team: I bring engineers, a product owner, a designer, and QA. I lead the architecture. AI executes. Nothing ships without senior review. Advisory: I come in as your technical advisor. Same judgment, scoped to what you need. Either way, there's a senior engineer on it from the first call to the final release. RECENT PROJECTS Automotive SaaS: A real-time pricing platform running 79M price combinations a month 24/7.

Businesses often need more than just a developer. They need someone who can understand the requirement properly, suggest the right approach, and build a product that works smoothly in real use. I help startups, founders, and growing businesses build web applications, mobile apps, SaaS products, MVPs, and custom business platforms with a strong focus on clarity, performance, and long term scalability. With 15+ years of experience in software development, I have worked on projects from idea stage to launch, and also on existing platforms that needed improvements, feature expansion, workflow refinement, or complete redevelopment. My work covers both frontend and backend, so clients do not need to manage multiple developers for one product. I focus on understanding the business goal first, then translating it into a practical and reliable solution. This helps reduce confusion during development and keeps the project aligned with the real requirement. **What I can help with:** ---------------------------- • Custom web application development • Mobile app development (Hybrid and Native) • SaaS product development • MVP development • Admin panels and dashboards • API development and third party integrations • Ecommerce and marketplace platforms • Maintenance and feature enhancement of existing products **Tech stack I work with includes:** React, Node.js, Laravel, Flutter, Python, WordPress, Shopify, Swift, Kotlin, and API based integrations. Clients usually appreciate working with me because I bring clear communication, structured execution, dependable support, and a practical approach to solving product challenges. Whether you need to build a product from scratch, improve an existing application, or develop a stable MVP with the right technical foundation, I can help move the project forward in a clear and efficient way. If you are looking for a developer who can combine technical execution with a strong understanding of business needs, I would be glad to discuss the scope and suggest the right approach.

Recent work: organic traffic +62%, TTI 2–3x faster, and a dashboard rebuild that grew weekly actives from 4K to 18K (+350%) in 4 months. 🏗 Architecture & Scalable Systems As a React Developer I design scalable component systems with Redux or Zustand; with Next.js I build hybrid rendering — SSR, SSG, ISR, API routes — tuned for performance and SEO. As a Full Stack Developer I work in Node.js, ExpressJS, and Python (Django, FastAPI), building REST APIs across PostgreSQL, MySQL, MongoDB, and Supabase, with WebSockets, Docker, and CI/CD on AWS or Vercel cutting release times 50%+. Modular patterns reduce technical debt and bug rates 30–40%. 🤖 AI Development & Intelligent Systems I build production-ready AI apps and agents with the OpenAI API and Claude, connecting LLMs to real product needs, not demos. As a Full Stack Developer and React Developer, I ship conversational interfaces, multi-step reasoning pipelines, ML features inside existing platforms, and AI-powered dashboards that save teams 15–25 hours/week. 📱 Mobile App Development Beyond the web, I build cross-platform apps with React Native for Android and iOS, sharing logic with the web codebase to cut delivery time up to 40%. As a Front End Developer who treats mobile as a first-class surface, I've shipped apps holding 4.5★+ store ratings. 🎨 Design-to-Code & Website Builds I turn Figma and Framer designs into pixel-perfect, responsive interfaces with Tailwind CSS and SCSS — landing pages, full websites, or redesigns, always polished and fast. As a Front End Developer I consistently hit Lighthouse 95+ and median LCP under 1.8s. 📈 Business-Oriented Engineering As a React Developer I've refactored unstable React codebases into maintainable systems, shipped Next.js platforms that grew organic acquisition, built Stripe subscription and marketplace flows, and handled API integration, cutting infra overhead 20–30%. One Full Stack Developer engagement took a signup funnel from 90 to 240/month (+165%) while halving server costs. ⚡ Performance & Optimization I treat Core Web Vitals like LCP and TTI as real product metrics, getting them 2–3x faster through code splitting, lazy loading, caching, and SSR/ISR/static rendering. As a Front End Developer obsessed with speed, I've taken pages from 6s+ to sub-2s, lifting conversion +38% and cutting bounce 25%+. 🔧 Primary Stack Frontend: React.js, Next.js, TypeScript, Redux, Zustand, Tailwind CSS, SCSS, Framer. Backend: Node.js, ExpressJS, Python (Django, FastAPI), REST, GraphQL, WebSockets. AI: OpenAI API, Claude, custom ML. Mobile: React Native, native Android. Infra: AWS, Vercel, Docker, CI/CD, PostgreSQL, MySQL, MongoDB, Redis, Supabase. Need a React Developer for a complex SPA or a Full Stack Developer to own the whole product?
