Senior Software Engineer focused on cloud-native fintech platforms, AI-assisted engineering, and end-to-end system architecture.
PolandWhat I'm looking for
I’m a Senior Software Engineer with 9+ years delivering full-stack, fintech and cloud-native platforms—from React and TypeScript frontends to PostgreSQL-backed Node.js APIs and AWS-hosted infrastructure.
I build end-to-end technical architectures for regulated, high-throughput environments, translating ambiguous product intent into precise technical specifications and executable briefs that accelerate delivery in fast-paced, startup-oriented cultures.
In my most recent role, I’ve owned target architecture for a next-generation AI-powered fintech developer platform: React/TypeScript, Node.js REST and GraphQL, PostgreSQL via Supabase, and AWS-managed infrastructure supporting multi-partner financial data orchestration at scale.
I also design AI-augmented engineering workflows with rigorous code review discipline—integrating Anthropic API with RAG for conversational querying, deploying LLM-driven extraction with structured outputs, and setting AI code review protocols to enforce correctness, security, and performance before merge.
Experience
Work history, roles, and key accomplishments
Defined and maintained the target technical architecture for an AI-powered fintech developer platform, spanning React/TypeScript, Node.js REST/GraphQL, Supabase-backed PostgreSQL, and AWS-managed serverless infrastructure. Integrated Anthropic-based RAG and LLM workflows (document extraction, pricing calculators, and AI code review) and built unified API gateway orchestration to support multi-part
Led planning and architectural design of CloudForge, a cloud-native application delivery platform built with React, TypeScript, and Node.js. Developed container orchestration, observability tooling, multi-tenant PostgreSQL data models, automated contract testing, and AWS-integrated CI/CD to speed releases and improve operational reliability.
Designed and implemented core backend services for the AstraCompute platform using Node.js RESTful APIs to enable dynamic workload scheduling and resource allocation. Built TypeScript-based configuration contracts, observability with AWS CloudWatch, and automated regression testing, and optimized a PostgreSQL telemetry store to improve analytics query performance.
Contributed to the Auralis platform by implementing signal processing modules in C++ and Python. Supported DSP testing and troubleshooting, and built internal tooling to automate nightly benchmark reporting across hardware variants.
