    Ever since I was a kid, I've been fascinated by computers. I was introduced to Linux almost 15 years ago, and that was the time I discovered my first true passion.. I worked as a software developer (iOS - Swift) and Linux system administrator, but I wasn't satisfied with neither developing corporate/commercial applications, nor repeating same routines like adding/removing users, setting up VPSs, configuring programs following the same conventions.. I needed something to satisfy my passion for creativity and problem solving/algorithmic/programmatic thinking, but that is still related to Linux.. Enter Bash, an amazing way to interact and utilize full potential of your Unix OS in a totally programmatic manner.. I've been perfecting my Bash skills for over 5 years now, and I have quite a lot of complex projects, successful jobs and happy clients to support that.. I'm also quite proficient with Python as well, but given my stand on mainstream appliances, I'm only interested in jobs utilizing core principles, I DON'T have any "domain-specific" skills, so please DON'T contact me about AI/Machine Learning/Trading/Full stack/bot automation etc, only basic python skills.. That being said, if you're looking for a Linux expert who thinks of Bash as a programming language and vim as an IDE, feel free to reach out and I'd be happy to provide my services! :)

    Hi there, and welcome to my profile! I'm the CEO of consulting agency Advascale. We're implementing such business processes as Continuous Integration, Continuous delivery, GitFlow, working in DevOps and Agile methodologies, and help our clients to get familiar with them. Below you can read my portfolio and an overview. Fullstack AWS Cloud Engineer, Solutions Architect, and DevOps. AWS Certified: — AWS Solutions Architect — AWS SysOps Administrator Full-stack AWS Cloud Engineer with 7 years of experience, I manage, troubleshoot, build, migrate your AWS cloud environment, including Linux servers, databases, DNS transfer, hosting. I'm also able to double-check your current AWS stack against the AWS well-architected framework (cost-optimization, scalability, reliability, performance efficiency, security, and operational excellence) * AWS skills: — Designing and deploying scalable, highly available, and fault-tolerant systems on AWS — Lift and shift of an existing on-premises application to AWS — Ingress and egress of data to and from AWS — Choosing the appropriate AWS service based on data, compute, database, or security requirements — Identifying appropriate use of AWS architectural best practices — Estimating AWS costs and identifying cost control mechanisms — Correctly using spot instances in your project makes your EC2 (ECS, EKS, EB) usage up to 80% cheaper! * DevOps skills: — Automation for the build and deployment of your app from Git repository to AWS (EC2/ECS/EKS/EB, Lambda, etc.) — Develop automation for Unix/Linux infrastructure with Bash and Python scripting. — Develop Shell/Chef/Ansible code to automate server builds, OS patches, and deployment of applications to dev, test, and production environments. — Design reliable infrastructures for IT products that are migrated from on-premise or developed for AWS platform using the infrastructure-as-a-code concept. — Write custom monitoring and integrated monitoring methods into deployment processes to develop self-healing solutions on Linux EC2 instances. — Manage multiple AWS accounts, enforced network security, user/group permissions, service performance, and cost. * Common jobs that I have done: — Introduce startups and individuals to the benefit of AWS. — Containerize native applications (PHP, Python, Nodejs, Java, Scala, Ruby, etc.) to run with AWS ECS, including 1 step build & deploy (git push) using CICD tools (Jenkins, GitlabCI, AWS CodeCommit). — Troubleshooting VPC/Networking issues, communication between AWS resources, like Lambda and private RDS/ElastiCache/EC2/etc. — Tighten security (IAM, VPC, Security Groups, S3 ACL, WAF, CloudTrail, etc.). — Setup serverless stack (Lambda, DynamoDB, S3, CloudFront). — Review proposed or existing AWS architecture for security, cost-optimization, HA, Backup, Performance, etc. — Setup secured access (OpenVPN, SSH tunnel) between on-premise and private subnets (VPC). Setup VPC Peering connection — Create CloudFormation templates for quick replication of AWS stack (deploy to multiple regions, easy to create and remove resources, etc.). Write Terraform stacks. ——— If you have questions about your AWS environment or an interesting project — just contact me, so we could discuss details.

    First thing off: I DON'T USE SKYPE (and other proprietary closed protocols and technologies: teamviewer etc.), but I have mail, jabber and jitsi. ✓ UNIX. Portable programming (C-99, POSIX, autotools), portable shell programming (POSIX.2) — dealt with many subtleties in different implementations. System programming. Embedded. ✓ My primary language is python now (see my Scripting profile). Currently learning django, ansible. I work fast, if in doubt, ask for the time estimate, beware, communication may take twice the time spent on coding, so it's always best to make up your mind before hiring! I'm honest, reliable and tenacious, and I don't remove bad feedback (enjoy!:) Lifetime warranty for my work (doesn't include new features though). The list of capabilities is not full, as I've experience ranging from Jenkins to writing parsers with lex/yacc, from IP traffic handling in C++ (libnetfilter_queue plus iptables custom kernel module) to product installers. I use Gentoo and EMACS. I'm easily searchable, and if you want, you can find any information about me outside of upwork. Aquila non captat muscas. Usually. But my rate effectively cuts off the stuff that everyone can do:) Also you may consider my agency (Laguz d.o.o.), there are junior programmers whom I supervise and ensure the work done. Should be about the same quality for a fraction of price. NB. If you want me to use some collaboration tools, usually it won't work. Few mail servers on Earth support my email, most of the time it's impossible for me to register.
