Full Stack Engineer

I’m a full-stack engineer with over 3 years of experience building scalable fintech applications, and a strong personal focus on blockchain development. Professionally, I’ve worked on data-driven platforms that prioritize reliability, usability, and performance — using technologies like React, NestJS, FastAPI, PostgreSQL, and modern cloud infrastructure.

Outside of work, I design and build Web3 projects that explore decentralized systems and financial transparency. My current project, Draco Platform, is a decentralized lottery DApp on Solana — now live on Devnet and planned for Mainnet deployment in the near future. I’ve developed its Anchor smart contracts with Rust and a backend indexing system to keep on-chain data updated.

I’m looking for a blockchain engineering role where I can combine my full-stack experience with hands-on smart contract development — contributing to the design of decentralized architectures, secure on-chain programs, and scalable backend systems that bridge Web2 and Web3.

Experience

Software Engineer

Morescope

2022 - 2025

Joined Morescope in its early stages as part of the first engineering team and contributed to the company’s growth from a small startup to its acquisition by the Nordic region’s leading carbon accounting platform. I built and maintained full-stack applications that help companies track and report CO₂ emissions from their financial transactions. I developed internal dashboards and admin tools that automated key workflows and reduced manual operations by 40%, improving both efficiency and data accuracy. Working closely with cross-functional teams, I delivered solutions quickly and iterated based on user feedback to optimize usability and performance. On the backend, I designed and implemented FastAPI services that integrated complex PostgreSQL and Databricks data pipelines for scalable, real-time reporting, while ensuring deployment reliability through Terraform during rapid product iteration.
