    — Among the Top 1% of Upwork Freelancers // Top Rated Plus Freelancer & Expert Vetted Freelancer — Ranked Top 5% in Python Across LinkedIn I have more than 10 years of experience in Full Stack Engineering and DevOps Engineering, encompassing projects in cloud systems, web applications, mobile applications, data mining, and automation. My current main area of interest is within large data-driven applications in a distributed, scalable, cloud environment. I have many years of experience in writing screen and data scrapers for online data mining applications (with experience automating scraping data from thousands of sites). While my preferred technologies include Python, Golang, R, React, AWS, Elasticsearch, and Terraform, I am also experienced in Javascript, Google Cloud Platform, AngularJS, Node.js, CloudFormation, and many more technology options. DATA ENGINEERING / DATA LAKES I have been designing, scaling, and implementing Data Lakes sense before we called them "data lakes". I have worked extensively with AWS Partners to train their teams and to deliver Data Lake solutions to the customers. I design and develop the ETL processes and am familiar with integrating a wide range of APIs. Tools I have used include: Python, Node.js, AWS Lambda, AWS S3, Tableau, Quicksight, PowerBI, Redshift, DynamoDB, MySQL, PostgreSQL, Aurora, AWS RDS, MongoDB, Elasticsearch, etc. I have integrated many third party tools to such Data Lakes including Google Analytics, Salesforce, Google Ads, Bing Ads, Facebook Ads, ServiceNow, and many other similar tools. DATA MINING I have been writing data scrapers and other data intensive scripts/ utilities for many years. My language of choice for many of these is Python or R, and I regularly work with Scrapy, BeautifulSoup, lxml, etc. However, I can successfully develop a utility in many scripting languages and packages, including: Bash, PHP, Ruby, Perl, etc. I have written screen scrapers for over 500 websites, including Google Search and Craigslist. I have a very high working knowledge of HTML, which helps me quickly write any screen scraper you find yourself needing. DEVOPS / AUTOMATION With most of my projects, I am responsible for everything from ground up. This, of course, includes the code of the application, but also the automated pipelines, automated deployments, version control, and Infrastructure-as-Code. I have vast experience with designing and developing system architectures in Google Cloud and Amazon Web Services. I have used many available DevOps tools in these projects, with my favorites consisting of Terraform, CloudFormation, Gitlab, Github, Jenkins, Ansible, Docker, Packer, AWS Code Services, TravisCI, and CircleCI. Whether you need to migrate data, design infrastructure, or automate pipelines and deployments, I have the experience and expertise to help. WEB BACKGROUND I have wide knowledge of many modern technologies in the web development stack -- from low-level networking protocols and system tweaking (debian, nginx, apache) to server-side programming (Python, PHP, Node.js) to client-side programming (HTML5 APIs, Javascript, AngularJS, React.js) to many NoSQL and SQL data providers (Elasticsearch, RDBMS, MongoDB, Redis, DynamoDB, etc). I could solve the programming task of any complexity for you. I prefer developing complex and unique web services and/or user interfaces rather than creating simple websites which are similar to each other.

    I'm a Penetration Tester and Cyber Security Specialist who is a professional in evaluating the security posture of Web-Applications (Websites) and ensuring the security of personal clients' online identities, accounts, devices, and networks, I've possessed my current knowledge through 3+ years of self-study and research plus 2+ years of work in the industry, protecting clients on a personal level and running vulnerability assessments against business websites, always leaving positive impression and impact, I hold a great record of being able to expertly provide the following services: - Perform comprehensive security checkups on Emails and Phone numbers and pinpoint security holes which often lead victims to be hacked with zero interaction nor awareness from them. - Assist in Account Recovery (Ex. Instagram, Facebook) - Educate thoroughly on the findings and remediations for a vulnerable target, equipping clients with enough information to trust themselves as they continue to utilize the technologies as normal with no fear of being targetted by hackers. - Investigate and educate on online frauds/scams, especially crypto ones, why and how they work, and how to distinguish between legit and not legit easily. - Clean up networks and devices from viruses/malware and ensure optimal patching for security. - Report fraud websites that impersonate legit businesses for a takedown. IMPORTANT: When it comes to cybersecurity-related services, there is a number of scammers not to be underestimated, whether within or outside of Upwork, therefore stay vigilant and keep in mind the following, 1. If you were scammed online via crypto, there's no one out there with the right to give a guarantee that they will be able to recover it for you despite how well furnished the so-called hacker's portfolio appears to be, the chance remains very slim and you should only pursue this kind of service for the sake of leaving no stone unturned knowing the high probability of failure, and you should only select a freelancer with a reputable profile and reviews to back up their activity because scammer accounts are usually fresh with no reviews and no verified ID, feel free to consult me to evaluate that. 2. Same applies to the request of hacking an account, there are complicated caveats that explain why it DOES NOT work the way you think it does but to keep it short, if you want someone's account hacked, aside from it being illegal and unethical and isn't the type of "service" I provide, the chance for it to work is about 1% to begin with, again, I'm available for consultation, account recovery is a different subject with a higher probability for success as long as it's your own account that was lost/hacked.
