I help startups with the UX/UI and web design of their products. This includes web apps, websites, landing pages, copywriting, and I can assist with frontend development where needed. My background of launching my own products and being a full stack developer helps me create practical designs that balance usability, aesthetics, development effort, and performance. I work to fixed price quotes for self-contained projects.
---
The best live example of my work is Checkbot (https://checkbot.io/), a browser extension that tests websites for SEO/speed/security problems. The entire project is my own work including coding the extension itself, UX/UI design, website design (the homepage is optimised to load in 0.7 seconds, 0.3MB data transferred), marketing, website copy, and website articles on web best practices.

Willing to relocate: no, but willing to travel/visit. I'm flexible with working hours, I usually work with clients from either Western Europe or the USA.
I do dev/devops/security, usually for startups or scale-ups or other small orgs with limited resources, and I've been doing that for 15+ years. So, if you:
* Have a slow web application that’s often down?
* Want to improve security and don’t know where to start?
* Have a legacy system that needs to be replaced?
* Are considering an acquisition but not sure about the technical side?
I can help with that. For example, in the past I have:
* Massively improved performance and reliability for a data visualization platform.
* Led a large effort to improve security for a cybersecurity SaaS.
* Built a micropayments system for a prominent media startup.
* Rebuilt an aging e-learning platform from scratch for a GDPR compliance SaaS.
* Conducted technical due diligence for acquisitions.

I am a backend expert, having built and maintained mission critical, low latency and highly available systems for several companies over the last 10 years, in addition to over 20 total years of software development experience. I learn new things extremely quickly. AWS preferred but not required (I hold a variety of certs, available here: https://www.credly.com/users/jon-north.ad78f0c8)
You will like working with me because I:
Concrete examples:* built the streaming data architecture for realtime game player tracking information (all games, 50ms SLA) and game stats for one of the top 3 US sports leagues (can’t name drop!) using Redpanda/Kafka on Azure+Terraform, and implemented its developer portal using Gravitee to provide first class streaming API support and monetization. Also built, deployed and maintained their ask-a-question-get-a-true-answer AI bot to expose 20+ years of stats to natural language fan questions!
* Implemented a vector DB for one of the leading AI image hallucination platforms (millions of users) to provide an image similarity service.
* replatformed dozens of complex quant jobs to AWS Lambda for a startup hedge fund (~$1B AUM), vastly improving QoS and maintenance cost. Line 1 to platform-in-prod time 3 months, including refactoring for fit. This was mission critical cannot-fail stuff and required extensive proof of correctness.
* built a ~50 node, AWS, Dockerized, Terraform-deployed distributed system to provide realtime, transformed trade data from crypto exchanges to a Kafka pipeline and data lake (fodder for an analytics platform). Met 5000msec SLA across arbitrarily many exchanges and ticker symbols. Blue-green deployment for complete CICD safety. Cloudwatch metrics proved SLA was met and provided general system oversight.
* built a framework to collapse dozens of singleton ETL programs into one config-driven, simple C# application performing the same functionality at ~80% reduction in maintenance cost year over year.

Available for remote work worldwide, very flexible across time zones. Looking for permanent or contract positions.
Hi! I’m Olga, an experienced software engineer looking for frontend or fullstack projects.
I have experience building greenfield projects and complex features that “just work,” as well as diving into complex legacy codebases, fixing “unfixable” bugs, and performing major refactoring.
In addition to React/Next.js and Node/Express.js development, I also have experience with cloud-native workflows (Golang + Kubernetes), OpenAI API integration and agentic workflows, native iOS development, and game development. Thanks to my multi-platform experience, I can help you port large products across different platforms.

I am a Lead Infrastructure Engineer with 20+ years of experience.
Whether your team is stuck troubleshooting infra issues, needs extra hands on an infra-heavy project or is just lacking tech leadership on the DevOps topics, contact me and we'll figure it out.
I prefer to work along the existing engineering teams, mentoring or training them while working together on the real tasks. This is a very effective and also a flexible way to learn and as a bonus, some work gets done on the way.
I am located in EU (Estonia) and work remotely with occasional on-site visits.
The usual topics are various AWS services, Elastic Stack, Linux, wide range of troubleshooting, infrastructure as code, logging & monitoring, managing cloud costs, but I find it rewarding to venture into new areas together with the team.

vCISO & Cloud Security (AWS, ISO 27001, Risk Management)
I’m an independent security consultant with 20+ years in operations and cloud security, now running a remote-first vCISO practice from Spain. I focus on helping AWS-based startups and SMBs (50–250 employees) strengthen their security posture, meet compliance goals, and prepare for audits.
Services I provide:
* vCISO retainer ($5k/month) – security strategy, governance, board reporting
* AWS security architecture reviews – design and remediation guidance
* ISO 27001 gap analysis & roadmap – prep for certification
* Risk assessments (NIST CSF, ISO 27005, CIS Controls)
* Cloud security program build-outs
Who I work with:
* SaaS / Internet companies scaling quickly on AWS
* Startups seeking a pragmatic, fractional CISO instead of hiring full-time
If you’re looking for someone to build or improve your security program, align it with compliance frameworks, and work directly with leadership/engineering, I’d love to chat.

Email: poetic.artifice@gmail.com
I am a seasoned (>13 years experience) full-stack staff-to-principal-level software engineer/consultant specializing in the backend, systems architecture, AI, platform engineering, internal tools, prototyping, and data engineering. In addition to strong programming and architectural skills, I'm a force multiplier for any team in either role through the three T's -- teaching, talking, and tooling. I also hold a US patent in the AI space.
In the past, I've taught a number of scientists and students to code in python; I've led and managed a number of high-impact engineering teams of up to 12; and pioneered a number of no- and low-code solutions for stream processing, data model and query generation, form building, workflow systems, and front-end construction for a variety of industries, including those with strong regulatory requirements and complex business rules such as healthcare and fintech. >10% of all medicare applications and millions of individuals currently flow through pioneering no-code systems I conceived and built and have ran in production for over a decade.
More recently, I've built a no-code automated form-filler and a workflow engine for coordinating LLMs and other generative AI processes, and on top of this a platform for both minimizing hallucinations and working with documents that are far too large for existing context window inputs or outputs using a novel, patented process that I invented; and applied these tools to various contracted projects requiring analysis and and cross-checking of information and other forms of integrity across textual and video/audio corpus data in a variety of domains (fiction and non-fiction).
I am also an improvisational pianist, published poet, and I've created novel algorithms and tools for studying and composing both music and poetry, which I have given a talk on at a recent functional programming conference.
I have extensive experience working for and running startups, software consulting shops, with some mid-sized company engineering experience as well; these give me a unique insight into speaking with customers and internal stake-holders, translating between engineering and other departments, gathering requirements, aligning stake-holders across departments on a vision and attainable timeline, and architecting/building/taking ownership over significant internal and customer-facing areas of responsibility.
If any of the above seems like a match for you and your organization or project, don't hesitate to reach out.
Willing to relocate: No, but willing to travel.

I have been writing high quality software across industries for more than a decade; inventing algorithms, contributing to existing codebases, and writing projects from scratch. My work includes compilers, libraries and language bindings, build systems, bootstrapping and reproducible builds, and a mountain of bugfixes. I work well independently and I am quite good at diving deep into problems and unblocking myself.
Recent work: I added prime path coverage and MC/DC support to GCC.
Send me an email and let me help you realise your idea or fix your problem. I'd love to have a chat and explore opportunities with you.
