Hi, I'm Nima Mokhtarian

Senior Software Engineer | Backend Team Lead

I design and lead reliable backend systems for banking, fintech, and data-intensive products. I have 10+ years of software engineering experience, including 5+ years focused on Java, Spring Boot, distributed systems, and production ownership.

My recent work includes domain-driven banking platforms, high-volume financial workflows, crypto-market infrastructure, and quantitative research tooling.

What I work on

  • Java 21, Spring Boot, REST APIs, asynchronous processing, and performance optimization
  • Domain-Driven Design, Clean and Hexagonal Architecture, modular monoliths, and microservices
  • Event-driven systems, transactional outbox/inbox patterns, reconciliation, and double-entry ledgers
  • PostgreSQL, MongoDB, Docker, Kubernetes, observability, and CI/CD
  • OAuth2, OIDC, FAPI 2.0, mTLS, Vault, OPA, and zero-trust service design
  • Technical leadership, architecture reviews, mentoring, and production support

Selected projects

Project What it demonstrates
Crypto Market Ingestion A Java 21 and Spring Boot service for scheduled and on-demand ingestion from CoinGecko and CryptoQuant, with PostgreSQL, resilience controls, Docker, OpenAPI, and automated tests.
Strategy Lab An extensible Python framework for backtesting and comparing signal-driven BTC/Gold allocation strategies, including walk-forward evaluation.
Nobitex NAV Bot A Spring Boot Telegram bot for investor NAV queries, member management, and subscription-cancellation workflows.
Crypto API Postman Kits Ready-to-import API collections for Binance, CoinGecko, CryptoQuant, CoinEx, Bitquery, Derive, Nobitex, and multi-chain wallet transactions.

Engineering background

  • Architected a domain-driven neo-bank platform spanning approximately 25 bounded contexts.
  • Led backend systems used across banking operations serving a combined customer population of more than 80 million.
  • Designed secure authentication and authorization flows for consumer banking and Open Banking environments.
  • Built and led market-data ingestion, portfolio, fund operations, and quantitative-research systems.
  • Authored architecture decision records and mentored engineers through design, delivery, and production ownership.
