pronounced as o-zee-or-ma-tchu-ku. It means The Gospel of God

If you cannot pronounce my igbo name you can also call me Alexa.

I am a product engineer and in the past 6 years I have worn a lot of hats:

• building full stack software
• designing system architecture
• technical customer support
• building and managing technical docs
• leading engineering teams
• managing products
• managing infrastructure
• facilitating internship an bootcamp programs
• mentoring software developers
• being an entrepreneur

I am a core software engineer but I pick up other skills so I can be whatever my team needs at any point in time to move forward

• Founding Product Engineer & TPM at Orra: We're building the fastest AI prediction market on Solana. I wear multiple hats here: building blockchain infrastructure, backend services, frontend features, managing infra and managing a small team of engineers as a technical product manager.
• AI Security Research: On the side, I independently study adversarial machine learning. I am learning how models degrade when people actively try to trick them, and how we can build AI systems that stay secure under real-world pressure. In the future i want to build a solution around this.

I generally treat tools as means to an end and my identity as an engineer aint tied to them. My focus is usually on quickly learning whatever is necessary to unblock the team and ensure we aren't accumulating tech debt.

• Languages & Frameworks: Python, FastAPI, Flask, Django, TypeScript, Node.js, React, Next.js, NestJS, C#, .NET Core (Web api and MVC)
• Databases & Caching: PostgreSQL, MongoDB, MySQL, Xata, Prisma, Drizzle, Redis cache patterns
• Architecture & QA: System design, data migration, E2E/unit/integration testing (Jest, xUnit, Mocha, Supertest, litesvm)

• Ecosystems: Solana (Anchor), Ethereum/EVM (Solidity, Hardhat, Ethers.js)
• Infrastructure: Multi-chain automated withdrawal systems, dispute resolution smart contracts, Filecoin Virtual Machine (FVM)

• Frameworks & Libraries: LangChain, LangGraph, CrewAI, PyTorch, TensorFlow, Hugging Face
• Vector DBs & RAG: LanceDB, PyVector, RAGAS for evaluation
• APIs: OpenAI, Gemini, Anthropic, Claude

• Cloud Platforms: AWS (Lambda, API Gateway, S3, RDS)
• Containers & Orchestration: Docker, Kubernetes
• CI/CD & Automation: GitHub Actions, Jenkins, Terraform, Hangfire
• Monitoring: Elastic Stack (ELK), Grafana

Sharing knowledge keeps the developer community moving forward. Here is how I give back:

• I break down complex engineering concepts into practical insights on Medium. Check out my articles for deep dives on system design, blockchain integration, and scaling infrastructure.

• Code Documenter AI Agent — I built an AI-powered system using GPT that improved API documentation generation by 95%
• CountryRegion / CountryRegionJS — Created location data APIs with 16,000+ downloads
• Axelar Network — Enhanced integration documentation for the Web3 community
• Phone Number Service (PNS) — Contributed Solidity smart contract docs and fixed security vulnerabilities
• NPM & NuGet Packages — NPM packages and .NET libraries on NuGet

• Codacy Pioneer: Selected as one of only 13 open-source creators globally to receive this honor.
• Top 40 African Women in Blockchain: Recognized by CRYPTOTVPLUS for contributions to the Web3 space.
• Web3 Mentor of the Year: Awarded the Gary Vaynerchuk Award at Learnable 2023 for helping new developers break into the industry.
• Hackathon Grand Prize Winner: Led the winning team for the 14G Mono Hackathon to build a modern fintech solution.
• TxE Africa Leadership Award: Two-time recipient for managing volunteer operations for events with over 10,000 attendees.

I am always happy to chat about interesting projects, architectural puzzles, or potential collaborations. I am especially interested in high-performance cloud architecture, Web3 infrastructure, and AI engineering.
