I'm an experienced Full Stack Engineer / Architect specialized on design and delivery of software solutions with both complex Backend and Frontend. As an Engineer, I have delivered a plenty of projects in various business domains, such as FinTech, AdTech, Marketing automation, Travel industry, Recruitment and HR, Telecommunications. I create robust, scalable and efficient Enterprise level applications of high complexity, intended to run within both classic on-premise environments, and in popular Cloud platforms, using such popular Backend programming languages as Java, Go, Python, PHP, and Javascript/Typescript with Node.js. I have experience using popular frameworks for each of these languages, such as for example Spring (several components) and GWT for Java, Django for Python, Symfony and Laravel for PHP, Expess.js with Node.js and others. Typically nowadays the Backend I use to deliver is a number of microservices with one or more exposed APIs, most often HTTP REST. For the Frontend, I have experience creating complex Web based dashboards using popular Javascript / Typescript based solutions, such as Angular 2+, React.js, and a big variety of different libraries. As part of architecture and design phase, I actively participate in the discussion of an upcoming solution, discovering and digging into the problem that we are trying to solve, providing you with comprehensive recommendations and coming up with a fully fledged design proposal, development phases and their estimation, as well as corresponding documentation afterwards. I also have an experience leading a small development team, providing it with an appropriate task splitting, basic engineering management, tech guidance, code reviews and support. As a supporter of "you build, you run" philosophy, I have a practical exposure to the DevOps, setting and using the CI/CD pipeline, with an active usage of IaaC tools, such as Terraform or Ansible. I actively use Docker in all the variety of possible ways: for development, testing, deployment, and in production - as well as have Kubernetes experience. Looking forward to working with you!

I solve hard backend and AI problems and take them all the way to production. I have 20 years of C/C++ experience, 15 years of Python, and a track record spanning real-time systems, LLM pipelines, embedded software, distributed trading, and full-stack products. • AI workflows, LLM pipelines, RAG, Python/FastAPI backends, and React • Performance-critical systems in C/C++, embedded C, distributed services, and cryptography • End-to-end ownership: research, architecture, implementation, deployment, Stripe, and technical-debt cleanup I’ve led the algorithms behind real-time tracking for half the world’s buses, built a trading system that ranked #1 globally for its strategy’s speed, and delivered AI and backend work for YC companies. If the problem is unusual, complex, or difficult to debug, I can help.

Most small teams don't have an AI problem — they have a "no one has time to build the thing" problem. I build the thing. I design and build practical AI-driven workflows for founders and small teams who are buried in repetitive work: inbox triage that never gets caught up, leads that go cold because no one followed up in time, or marketing content that never gets made because there's no time to turn photos and notes into posts. My background is business, not computer science — an MBA and an econ degree, not a CS degree — which turns out to be an advantage here. I've spent more time thinking about how a business actually runs than about elegant code for its own sake, so what I build is aimed at your actual bottleneck, not the most technically interesting solution. Recent build: a fully automated research-and-scoring pipeline that replaced dozens of hours of manual work a month with a repeatable system — data pulled and normalized automatically, ambiguous cases escalated for a closer look, every result scored with a plain-language reason attached instead of a black-box number. (Full case study available on request.) I also design and ship software end-to-end — including a live iOS app on the App Store, built solo from scratch — so this isn't theory. I build things that actually run, and I've done it working independently and remotely for years. What I can build for you: - Inbox & lead follow-up automation — flags what's urgent, drafts replies in your voice, catches leads going cold - CRM / customer reactivation — finds contacts who've gone quiet and drafts personalized win-back messages - Content automation — turns raw photos/notes into ready-to-post marketing copy - AI audit — a clear map of where automation would actually save you time, with a prioritized plan (no code required to start) I respond fast, write like a person (not a copy-pasted proposal), and only pitch what I think will actually work for your specific setup.
