CEO
2020 - PRESENT
Wonop
- Made a front end in React and TypeScript, enabling the customers to sign up, create natural language processes, and execute them on the back end.
- Made the back end using Django, Django REST framework, and Python. The back end was integrated with Stripe and allowed social login.
- Built a high-performance natural language engine in C++ with Python bindings using PyBind11.
- Built a background worker using Celery that allowed the execution of the C++ code through a REST interface.
- Created deployment manifests for Kubernetes and Docker images for the above components.
- Created infrastructure for continuous integration and continuous delivery.

Fetch.AI
- Created a crypto-currency wallet using React and Electron to enable users to interact with the Fetch.AI network. This wallet enabled users to send and receive tokens on the Fetch.AI network.
- Created block explorer using Django, Django REST framework, and PostgreSQL that kept a log of all transactions that had happened on the network.
- Made a transpiler that could transpile Solidity code into the Fetch.AI native smart contract language Etch.
- Led the codebase development that allowed the company to raise $6,000,000 in less than 60 seconds.
- Managed the planning with the leadership team and oversaw code development.
- Led four teams with different responsibilities inside the company.
- Contributed to all parts of the codebase both on the front end, back ends, and the blockchain.

Senior Software Engineer
2018 - 2018
Fetch.AI
- Designed an MVP crypto-currency wallet using React and Electron. This MVP had the ability to let users perform simple transactions and searches.
- Designed the blockchain architecture and created an MVP using C++.
- Wrote the first version of a vectorized math library based on fixed points in C++. This code used SSE and AVX intrinsics alongside template unrolling to optimize the code on the assembly level.
- Mentored junior developers to ensure high code quality.
- Oversaw the development and created the initial system for code reviews.
