Good day.
I have deep expertise in developing complex backend systems, particularly in FinTech and high-load projects. I am ready to take responsibility for the architecture, implementation, and support of backend infrastructure for your investment platform.
Key competencies:
• Node.js (NestJS), TypeScript — development of efficient microservices with an emphasis on scalability, fault-tolerance, and secure data processing;
• Spring Boot (Java 17+) — usage in scenarios with high requirements for multithreading, transaction processing, and integration with payment systems;
• Architecture — designing scalable services considering DDD, CQRS, event-driven approaches (Kafka, RabbitMQ), multi-level authorization (RBAC, OAuth2), multi-tenancy, rate limiting, and throttling;
• Integrations — implemented connections with KYC/AML providers (Sumsub, Veriff, ComplyAdvantage), payment gateways, as well as analytical tools;
… • Infrastructure — experience setting up CI/CD pipelines (GitHub Actions, GitLab CI), deployment via Docker + Helm, Kubernetes (EKS, GKE), centralized logging (ELK, Loki), observability (Prometheus, Grafana, Sentry, OpenTelemetry);
• Security — implementation of encryption (AES, RSA), key management (Vault, AWS KMS), access auditing, logging of critical operations, compliance with PCI DSS, GDPR;
• Data storage — PostgreSQL (sharding, partitioning), Redis, MongoDB, TimescaleDB, ClickHouse for financial analytics;
• Cloud-ready approach — applying DevSecOps practices, considering zero-downtime deployment, automatic recovery, horizontal scaling.
I have experience forming the technical core of a team, implementing code review standards, migration strategies, contract testing (Pact), and coverage of critical modules with tests (unit + integration).
Ready for a deeper discussion of the architecture map and roadmap. I can join as an architect, lead developer, or consultant.
