Backend & API Development
Expertise in Node.js, Express.js, NestJS, TypeScript, REST APIs, GraphQL, Apollo, and WebSockets. Design and implementation of microservices and event-driven systems, including API performance optimization and backend architecture decisions.
Frontend Development
Proficiency in React, Next.js, Redux Toolkit, Material UI, and Tailwind CSS. Delivery of production-ready interfaces with focus on Core Web Vitals, code splitting, lazy loading, and bundle analysis to improve performance metrics such as First Contentful Paint.
Cloud & DevOps
Hands-on experience with AWS and GCP, Docker, Terraform, and CI/CD pipelines using GitHub Actions. Automation of cloud releases and management of cloud deployments for Node.js services backed by PostgreSQL and MongoDB.
Data & Caching
Knowledge of MongoDB, PostgreSQL, MySQL, schema design, indexing, aggregation pipelines, query optimization, and Redis for caching and idempotency to prevent duplicate calls and reduce costs.
Security & Authorization
Implementation of OAuth2, JWT, OWASP-related application security controls, RBAC, and ABAC policies, replacing scattered application-layer permission checks with centralized solutions.
Testing & Observability
Application of Jest, load testing, and OpenTelemetry traces for production debugging and observability. Load-tested services at approximately 1,000 requests per second with no failed requests observed.
Applied AI & LLM Integration
Development of AI agents and LLM-as-judge evaluation loops using Google ADK, OpenAI, Anthropic Claude, LangChain, RAG, and LLM evaluation techniques. Shipped 4+ production AI agents for company research and risk assessment.
KYB/KYC/AML API Integration
Unification of 6+ KYB/KYC/AML APIs behind one workflow, including Veriff and World-Check, supporting company research and compliance risk assessment.

Project history
AI compliance SaaS startup with a four-engineer team. Built the MVP in 8 weeks, securing the company's first client. Delivered React/Next.js interfaces, Node.js APIs, and cloud deployments. Unified 6+ KYB/KYC/AML APIs, resolved a $6K/6-hour LLM cost incident with caching and idempotency, shipped 4+ production AI agents using Google ADK, built an LLM-as-judge evaluation loop, automated GCP releases with CI/CD and Terraform, and provided technical direction and code reviews.
Enterprise cloud-security platform (Kscope AI / Kaleidoscope). Reduced API latency ~20% system-wide by optimizing database queries using OpenTelemetry traces. Load-tested the system at ~1,000 requests/second with no failed requests. Centralized RBAC and ABAC policies, reduced duplicate dashboard code with reusable React/Material UI components and GraphQL APIs, and improved First Contentful Paint from 4.2s to 1.7s.
Concurrent engagement. Shipped the customer-facing frontend for Insurance-Online, a German white-label insurance platform reusable across multiple brand configurations. Co-built The-Life-Script, a Next.js/TypeScript product that turns guided user input into AI-generated book content, covers, and print-ready output. Documented 100% of application endpoints using OpenAPI (OAS) and helped establish the team's API documentation standard.
