Recommendations

People I’ve shipped with

Amirreza Karimyrad

Lead software engineer

2026
I had the pleasure of working with Omid and I can tell he really knows his stuff when it comes to AI and agents. It's not just surface level for him, he actually understands how these systems are built and how to make them work reliably in real products. He's dependable, learns new things fast, and always thinks about the bigger picture, not just the code in front of him. He is smart, moves fast and support his team. Any team that wants someone with real depth in AI would be lucky to have him.

Daniel Alejandro Hernández Llerena

Senior Backend Engineer

2025
Omid has a strong grasp of AI-assisted development and applies it thoughtfully to ship high-quality, reliable solutions. He's dependable, quick to pick up new systems, and brings a full-stack mindset to everything he works on, the kind of engineer you'd want on any team looking for real AI fluency. I had the chance to work alongside him at Block Labs, and he quickly stood out as someone you could hand a hard problem to and just trust it'd get solved. Also I want to highlight, he excel working in teamwork, he is kind and have very good soft skills.

Suroor Gupta

Engineering Manager

2024
I worked with Omid while he was a Senior Flutter Developer on our team. What stood out about Omid is that he never treated his scope as fixed to the frontend. He took the initiative to go deep on backend knowledge transfer, building a real working understanding of how the systems underneath his Flutter work actually functioned, and approached it with the same seriousness he brings to his core mobile work. That's the mark of an engineer who thinks in full-stack terms, not just a mobile specialist bolting on backend familiarity. Omid brought consistency and quality to everything he touched, and his range across the stack makes him a strong fit for teams that need mobile depth backed by genuine backend fluency.

2025
I've had the pleasure of managing Omid and have consistently been impressed by his technical ability, professionalism and approach to engineering. Omid takes ownership of his work, approaches complex problems methodically and can be trusted to deliver high quality solutions with minimal oversight. One of his greatest strengths is how calm he remains under pressure. Even when priorities shift or challenges arise, he brings a level-headed approach that has a positive influence on those around him.

2024
I've known Omid for a while and we've worked on a few projects together outside of work. He's a really strong engineer and someone I can always rely on. He knows his stuff, solves problems quickly, and is great to work with. I'd definitely recommend him.

Forward Deployed Engineer / Senior Full-Stack Engineer

Seven years in crypto and fintech. I came up mobile-first with Flutter and Dart, then learned the rest of the stack in production: TypeScript, NestJS, React, Go, and the backend plumbing that keeps money moving.

I'm at Block Labs on Best Wallet right now. Multi-chain non-custodial wallet, 250K+ monthly active users. Flutter on the client, NestJS and Go behind it. I sat with Wirex and Fireblocks engineers from discovery through go-live, wrote the runbook support could run after handoff, and fixed the production bugs that only show up at scale.

Before that, four years at CoDeTech. Ping Exchange, CorePass, XCB HODLER, WebRTC messaging. I led five engineers on CorePass identity and KYC for a stretch.

AI and agents are part of daily work now. LLMs, code agents, MCP, RAG, evals, guardrails. On Memex I work on SuperAgent: preset child agents, schema-validated timeline cards, human confirm on mutating tools, loop detection, on-device storage. Guardrail Agent and IntentGuard are portfolio demos of the same idea: natural language to schema to policy to approve before anything hits a chain.

Open source: Guardrail Agent, EngagePulse, IntentGuard, Memex (lead contributor, 726 GitHub stars), dart_agent_core.
