About me
I'm Arash Dolati Mehr, a Senior Backend Developer with 15 years of experience, including 7+ years in blockchain technologies. I specialize in building scalable, secure backend systems using Go, PHP, and Python. I'm an expert in the Web3 stack, proficient in Solidity smart contract development and designing dApps on Ethereum. I have a proven track record of leading teams and delivering complex projects, such as an NFT-based game smart contract used by over 12,000 users and blockchain-based distributed file storage. I deployed smart contracts that automated over 80% of key business processes. I am a strong open-source contributor, maintaining a Go-based distributed storage module (300+ stars). My expertise also covers DevOps, CI/CD, Kubernetes, and cloud architecture (AWS/DigitalOcean). I focus on continuous learning, including Zero-Knowledge Proofs and advanced Gas Optimization. I share my knowledge through technical writing on Dev.to and Medium.

Work experience

Logo Yazılım– Istanbul, Turkey
September 2015 – July 2018
Job title
Senior Backend Engineer
Work experience & achievements
As a Senior Backend Engineer at Logo Yazılım, one of Turkey’s leading enterprise software companies, I contributed to the design and development of scalable backend systems for ERP and financial management solutions. My focus was on building reliable APIs and distributed services in Go and PHP that supported thousands of corporate users across retail and manufacturing sectors. I optimized core database queries and improved API response times by 35% through caching layers and asynchronous task queues. In this role, I also helped modernize the company’s deployment pipelines by introducing Docker-based containerization and GitLab CI/CD automation, which reduced deployment times from hours to minutes. Working closely with DevOps teams, I participated in transitioning legacy monolithic systems toward microservice-oriented architectures — a move that improved maintainability, scalability, and long-term system resilience.
Akbank Innovation Lab– Istanbul, Turkey
November 2018 – September 2021
Job title
Blockchain Integration Lead
Work experience & achievements
At Akbank Innovation Lab, I spearheaded blockchain adoption initiatives, building decentralized financial prototypes and smart contract solutions on Ethereum-compatible networks. My key achievement was designing a secure settlement layer for internal banking operations, improving transparency and auditability of inter-departmental transfers. I also developed an internal blockchain simulator for testing and auditing contract behavior before production deployment. Working alongside cybersecurity and compliance teams, I helped formulate technical standards for smart contract audits and transaction monitoring. I contributed to pilot programs integrating blockchain identity (DID) solutions for KYC processes, which reduced onboarding time by 25%. This experience solidified my expertise in regulated blockchain environments and enterprise-grade Web3 architecture.
Trendyol Group– Istanbul, Turkey
January 2022 – July 2023
Job title
Lead Backend & Infrastructure Architect
Work experience & achievements
As Lead Backend & Infrastructure Architect at Trendyol, I was responsible for scaling backend systems that handled millions of transactions per day. My work involved designing distributed systems with Go and gRPC, implementing asynchronous event-driven architecture using Kafka and Redis Streams, and optimizing request throughput under heavy load. I led a cross-functional engineering team focused on reliability engineering and observability. We integrated Prometheus and Grafana dashboards across all production clusters, enabling real-time performance insight and automated alerting. In parallel, I drove cloud cost optimization strategies on AWS and DigitalOcean, achieving a 22% reduction in infrastructure expenses. This role represented the culmination of my decade-long experience in backend architecture, DevOps, and blockchain-aligned infrastructure design.
