Досвід роботи

Core Full Stack Engineer

з 11.2025 по 07.2026 (9 місяців)
US-based Stealth Fintech Startup (NDA), Remote (Finance, banking, and insurance)

Contract full-stack engineer for a cross-border US-based fintech platform, working across data integrations, payment workflows, dashboards, authorization, and production operations.

• Integrated 30+ official and commercial data providers across jurisdictions; built provider-specific adapters and normalized inconsistent schemas, languages, identifiers, and error behavior into shared internal models.
• Implemented payment and reconciliation workflows with Stripe Connect, webhooks, refunds, fees, state controls, and duplicate-event prevention. Describe the flow as a marketplace only if its connected-account transfer model confirms that label.
• Migrated relevant dashboard surfaces to Next.js 15 and React 19 Server Components, reducing a measured client-side bundle by ~30%.
• Built and operated production infrastructure across Linux, AWS, Docker, Nginx, TLS, DNS, secrets, backups, CI/CD, monitoring, and incident response.
• Implemented tenant-scoped authorization and role-based access controls for security-sensitive application paths.

Security Product Engineer

з 08.2025 по нині (1 рік)
USK Group LLC | Florida, США, Remote (IT)

Security product engineering for AI-native and tool-connected systems, with a focus on controlled testing, evidence quality, and developer-actionable remediation.
• Built and maintained a TypeScript AI-agent security assessment CLI with 39 audit modules: 23 passive and 16 active.
• Implemented adapters for MCP, A2A, REST, GraphQL, gRPC, OpenAI function calling, and LangChain tools.
• Built controlled active-testing workflows for injection, SSRF, authentication and session boundaries, tool shadowing, chained exploits, fuzzing, and bounded side-effect evidence collection.
• Developed repository/source audits, capability graphs, findings deduplication, evidence/confidence tiers, SARIF output, regression fixtures, and remediation-oriented reporting.
• Conducted coordinated disclosure of security findings to affected maintainers; public confirmation, patches, advisories, and CVE status remain separate claim states.

Full stack software engineer

з 06.2023 по 11.2025 (2 роки 6 місяців)
Independent Consultant | Florida, USA, Remote (IT)

Technical partner for US and European clients. Delivered full-stack client and self-directed systems across APIs, data pipelines, multi-tenant workflows, infrastructure, and AI-enabled product features.

• Decomposed and restructured applications into modular Dockerized frontend, backend, and service components; owned reusable TypeScript types, shared modules, API behavior, and deployments.
• Built ingestion and transformation pipelines using scheduled batches, polling, webhooks, streaming, and scraping across financial, registry, telemetry, enrichment, and AI-processed data.
• Improved separate performance-critical paths from ~600ms to ~360ms and ~320ms to ~85ms; contributed to a workflow reduction from ~12 hours to under 3 hours through database, batching, parallelization, and application changes.
• Built 10+ Telegram bots and integrated applications, including an AI real-estate visualization workflow that returned furnished-room concepts from submitted images.
• Owned production delivery across Docker/Linux, Nginx, TLS, backups, monitoring, CI/CD, and incident response.
