Hello Here are my practical projects. National Bank of Pakistan (NBP) — Ridgebot VAPT Solution POC (2023) Conducted a Proof of Concept (POC) for the Ridgebot Vulnerability Assessment and Penetration Testing solution. Set prerequisites at the customer's premises and deployed the complete solution. Trained customer resources on utilizing Ridgebot effectively. Whitelisted necessary IPs and ports, ran scans, and generated comprehensive reports. Obtained customer sign-off upon successful completion of the POC. Led 40+ full-scope penetration testing engagements focusing heavily on API security, broken object-level authorization (BOLA), and complex business logic flaws in financial and healthcare systems. • Assessed custom token systems (JWT, OAuth 2.0), evaluating signing algorithms, secret storage, and session revocation mechanics to prevent account takeover risks. • Collaborated cross-functionally with development and DevOps teams to embed security gates, contract-level validation tests, and threat modeling into the software development lifecycle (SDLC). • Performed rigorous revalidation testing, confirming complete remediation of critical authorization bugs and enforcing strict data isolation standard across multi-tenant applications.

Hi, I'm Denis, a full-stack developer with hands-on experience building automation tools for security assessments. I've worked on offensive security projects involving data harvesting, API reconnaissance, and proof-of-concept generation for penetration testing. I understand your needs: a lean toolkit that chains OSINT findings into actionable intelligence. The scripts must be portable, well-commented, and deployable on fresh Linux environments without friction. My approach: 1. **Requirements review** – Lock down target data points: DNS enumeration, subdomain discovery, metadata extraction, and misconfigurations. 2. **Modular design** – Build dependency-light scripts with clear input/output contracts for seamless chaining. Python handles data processing and APIs; JavaScript covers browser-based reconnaissance if needed. 3. **Deployment** – Single-command install script, pinned dependencies, and reproducible test runs against a sample domain. 4. **Live engagement reliability** – Fast results without false positives. I'll implement rate-limit handling, error recovery for API failures, and clear logging for mid-engagement debugging. 5. **Resilience** – Retry logic with exponential backoff and easy endpoint swapping if services fail during assessment. I'm ready to start immediately. Let's discuss the details. Thanks, Denis.

Hey, I can build the Python and JavaScript OSINT toolkit to automate DNS/subdomain discovery, metadata collection and common misconfiguration checks, while keeping the scripts portable and easy to adapt during testing. I’ll also include the README, pinned dependencies where needed, and a reproducible test-domain example on a fresh Linux setup. I’ve worked on Python automation and security-focused scripting before and can keep the implementation clean and practical. If you share the target workflow, I’d be happy to discuss the exact modules and testing approach. Best regards, Fahad.

For this toolkit, I’d keep OSINT collection separate from impact-validation modules, so DNS, subdomain, metadata, and misconfiguration findings stay reusable while PoCs can be safely swapped or extended during an assessment. I can build the Python and JavaScript utilities with portability and maintainability as the two main priorities. Wherever native libraries are sufficient, I’d avoid dependencies; where packages materially improve reliability, versions would be pinned with a one-command setup. Output can be normalized to JSON/text so findings can feed directly into reports or follow-up validation steps. I handle projects end to end, including architecture, implementation, testing, documentation, and reproducible deployment. For security-sensitive tooling, I’d also keep scope controls explicit so test-domain examples and exploit demonstrations remain predictable and easy to modify during live engagements. The closest relevant project is FileChannels, where I worked on secure file sharing, password-protected documents, WebRTC, PubNub messaging, CRM integrations, browser extensions, and multiple client applications. That required working across authentication, access control, real-time communication, and integration boundaries rather than only frontend development.

Mapping the organisation's web surface requires handling dynamic JavaScript rendering for accurate subdomain discovery. I build this by using Puppeteer in Node.js, also Python scripts with BeautifulSoup for static analysis, chaining findings into proof-of-concept exploits. Do you have a preference for how detailed the web surface mapping should be, like specific types of links to prioritize? I need the scope confirmation to begin. 5.0 rating across 10 reviews, Preferred Freelancer.

As a seasoned tech specialist with a proficiency in Automation and Python, I believe I'm the ideal candidate for your OSINT JS/Python Pen Testing project. Over the years, I've consistently demonstrated my ability to develop lean, efficient scripts that yield actionable results in penetration-testing scenarios. My core focus is automating open-source intelligence collection while ensuring portability and zero external dependencies as you require. Having worked on numerous red-team projects in the past, I understand firsthand what sets an impressive script apart. It's not just about raw data; it's about chain findings into insightful, impactful actionable steps. My solutions are designed with this very principle in mind. Additionally, my commitment to clear inline comments means that not only can you expect well-documented scripts, but also have the flexibility to tweak payloads during live tests. In terms of delivery, I believe in going beyond meeting expectations – it's about delivering results that can effortlessly "wow." So not only will I provide you with meticulously crafted source files and a detailed README covering all aspects of usage but also demonstrate successful data extraction against a test domain

@HadiDar786

Hi, I've reviewed your project "OSINT JS/Python Pen Testing" and I have solid Python development experience, including building APIs with FastAPI, for work like this. I can put together a clean, well-tested implementation and keep you updated as I go. Happy to discuss the details.

@codeandcommand

Node or Python for the toolkit's core scripts? I have built OSINT scrapers before, recon automation, data enrichment, the kind of thing that needs to run unattended without breaking on rate limits. I would structure each tool as a standalone module with clean docs so your team can plug new ones in fast. Can start today, first module ready in 3 days. Budget and timeline here are starting points, we will lock in real numbers once I see the full tool list. Let me know and I will send a plan.

@jonasdedzo

Hello, I can build a lean, portable OSINT toolkit in Python and JavaScript for authorized penetration-testing engagements, focused on repeatable reconnaissance and assessment reporting. I’d structure the scripts to collect DNS/subdomain information, web-surface details, metadata, and common configuration issues, then normalize the findings into useful outputs that can support an assessment. Where proof-of-concept testing is required, I can keep it strictly within an authorized test environment and use safe, reproducible demonstrations rather than destructive payloads. I’ll keep dependencies minimal, pin versions where needed, add clear inline comments, and provide a concise README with installation, usage, inputs, and expected outputs. I’ll also package everything so a fresh Linux VM can reproduce the example run with a single setup command. I can provide relevant security/automation experience details honestly, but I won’t claim red-team projects I cannot verify. Looking forward to work with you. Thanks
