Work experience

Product Engineer / Fullstack Developer

from 01.2026 to now (9 months)
Misia-AI, Дистанційно (IT)

Worked at the intersection of product discovery, business analysis, design, and engineering on an AI-powered B2B platform delivered through web, Slack, Microsoft Teams, and email. Combined product ownership with hands-on fullstack development, taking initiatives from loosely defined owner ideas to documented requirements, team-ready scope, and production implementation.

Product & Delivery Ownership
Worked directly with the product owner to turn business ideas into use cases, user flows, functional requirements, priorities, and implementation scope. Owned product and technical documentation, coordinated developers and designers, clarified ambiguous requirements and edge cases, and aligned business and UX goals with technical constraints.

Structured Jira backlog and workflows and helped establish a consistent delivery process from discovery through design and development. Shaped areas such as AI usage and cost analytics, idea management, integrations, and knowledge workflows, evaluating scope, complexity, and pragmatic trade-offs before implementation.

Engineering & Architecture
Designed and implemented core functionality with Python, TypeScript, React, FastAPI, PostgreSQL, and AWS. Built Slack and Microsoft Teams integrations, backend APIs, asynchronous processing, and event-driven flows using Lambda, API Gateway, SQS, SNS, SES, RDS Proxy, Bedrock, and Terraform.

AI & Data
Worked on LLM orchestration, idea structuring, clarification, summarization, duplicate detection, extraction pipelines, and structured outputs. Contributed to document-to-knowledge ingestion and AI usage analytics by tenant, department, user, model, and time period, including dashboard integration and streaming chat UX.

Product Engineer / Head of Frontend Engineering

from 03.2023 to 02.2026 (3 years)
Jet-Bet, Дистанційно (IT)

Owned product development beyond implementation on a high-load online gaming platform, combining product decision-making, frontend engineering, analytics, and machine learning. Worked across the full path from deciding what was worth building and choosing pragmatic trade-offs to implementation and measurement.

Product Ownership & Decision-Making
Participated in defining what to build, why it mattered, and which solution best balanced user and business value, delivery time, technical complexity, and cost. Worked with stakeholders on feature scope and alternative approaches, challenged low-value or over-engineered solutions, and translated decisions into concrete UX and engineering work.

Used funnels, business metrics, user behavior data, and A/B tests to support prioritization and evaluate released features.

Engineering & UX
Built and scaled a responsive frontend in React, TypeScript, fp-ts, and Mantine; integrated multiple game providers through APIs and iframe; and implemented live betting views, real-time chat, profiles, tipping, likes, achievements, carousels, and interactive mechanics. Applied Feature-Sliced Design and performance techniques including lazy loading, Suspense, progressive images, internationalization, semantic HTML, and monitoring of CLS and FCP.

Analytics, BI & Machine Learning
Built admin and analytics capabilities for LTV, Churn, GGR, NGR, CPA, and CAC using PostgreSQL, Power BI, custom visualizations, Matomo, Google Analytics, and Prometheus. Designed recommendation and predictive models with LightGBM, scikit-learn, Spark, and FastAPI for personalization, churn, LTV, and acquisition analysis.

Key Results
Helped build and evolve the product from scratch while combining product ownership with hands-on engineering, analytics, and machine learning, creating a tighter feedback loop between business decisions and implementation.

Fullstack Developer

from 02.2022 to 03.2023 (1 year 2 months)
Outsource, Дистанційно (IT)

Worked on multiple B2B and B2C projects in an outsourcing environment, delivering fullstack development, analytics, and product-oriented technical solutions for clients across different domains.

Designed, developed, and maintained web applications using modern frontend and backend technologies, including React, TypeScript, JavaScript, Python, SQL, REST APIs, and relational databases. Built user-facing interfaces, internal dashboards, integrations with third-party services, and backend business logic for client projects with different requirements and architectures.

Participated in the full product lifecycle: requirements clarification, feature implementation, bug fixing, refactoring, performance optimization, analytics instrumentation, and support of production systems. Worked closely with business stakeholders, designers, analysts, and cross-functional teams to translate business requirements into practical technical solutions.

Implemented data collection, reporting, and analytics workflows for business and product teams. Built dashboards, prepared reports, analyzed funnels and user behavior, and supported decision-making with actionable insights. Worked with B2B and B2C metrics, customer behavior analysis, retention-related indicators, and operational reporting.

Contributed to projects involving admin panels, CRM-like interfaces, internal tools, client portals, and customer-facing platforms. Focused on building scalable and maintainable solutions, improving usability, and aligning technical implementation with business goals.

Adapted quickly to different business domains, codebases, and client processes, balancing engineering quality with delivery speed in a multi-project outsourcing environment.

Key Results
Successfully delivered features across multiple client projects, improved reporting and visibility for business stakeholders, and provided reliable fullstack support in fast-changing product environments.
