In early 2026, Luka Buzaladze, a Senior Software Engineer based in Toronto, Canada, commissioned our firm Path Law Group to pursue an O-1A visa in connection with his transition into a Senior Software Engineer role with dYdX Trading Inc. (dba dYdX Labs), one of the world's leading decentralized cryptocurrency exchanges. Buzaladze's six-year engineering career was entirely self-taught, with roots in Georgia before he relocated to Canada. This career had spanned some of the most technically demanding challenges in digital asset trading, including rebuilding Bitbuy's exchange operations from the ground up as one of its earliest engineers, and later serving as the first engineer at Pocket Protector, where he led a complete rewrite of the platform's trading architecture during a period of hypergrowth where his work helped drive the acquisition that ultimately connected him to dYdX.
The mission
dYdX, acting as petitioner, needed to secure Buzaladze's work authorization so he could relocate to the United States and step into a central engineering role supporting the company's trading infrastructure. The timing mattered: dYdX was preparing to expand its U.S. operations and launch new products, including spot cryptocurrency trading on the Solana blockchain, and needed specialized engineering talent in place to support that growth. In the role, Buzaladze would be responsible for the architecture and optimization of dYdX's transaction processing frameworks, execution engines, and blockchain integrations. This infrastructure is central to a platform that has processed more than $1.5 trillion in cumulative trading volume.
The most challenging issue was translating a career built almost entirely inside fast-moving crypto startups and a Canadian cryptocurrency exchange without advanced degrees, patents, or traditional academic accolades into the "distinguished reputation," "critical role," and "original contribution" standards demanded by the O-1A's extraordinary-ability classification. An initial consultation on August 18, 2025 with our team, alongside dYdX leadership, surfaced an early weakness: Buzaladze's most visible media presence at the time was tied to bidzer.ge, a Georgian slang-dictionary platform he built as a teenager, which didn't cleanly satisfy "published material...relating to work in the field." The team recommended engaging a publicist to secure additional coverage in outlets that would speak directly to his fintech engineering work.
The strategy
From that consultation, the Path Law Group team built a petition anchored across four of the alternative O-1A evidentiary criteria:
- Leading or critical roles for distinguished organizations: Established by including Buzaladze's sole ownership of Bitbuy's mission-critical internal operations dashboard (used by 100+ employees across verification, compliance, and transactions teams), his role as first engineer at Pocket Protector leading a complete rewrite of its trading infrastructure during hypergrowth, senior engineering work at Lazer Technologies, and his incoming leadership role at dYdX.
- Original contributions of major significance: Established by including proof he had reduced Pocket Protector's trade execution latency from roughly four seconds to 200 milliseconds, scaled its annualized trading volume from approximately $10 million to more than $1 billion, and independently designed Bitbuy's operations dashboard, which cut suspicious transaction reporting time from about two hours to two minutes and helped the company's support team scale from five to roughly 100 people.
- National and international recognition through published material: Secured via features in Analytics Insight, Distractify, NewsBlaze, and blogTO profiling Buzaladze's engineering career and unconventional, self-taught path into fintech.
- High salary or remuneration relative to others in the field: Supported by financial statements from Buzaladze's wholly owned technology consulting corporation, showing income well above U.S. Bureau of Labor Statistics benchmarks for software engineers.
Building this record required detailed supervisory and collaborator testimony. We acquired five recommendation letters from figures including Eddie Zhang (President, dYdX), Avinash Jamurath (former VP of Engineering, Bitbuy), Garrett Skrovina (Head of Crypto, Lazer Technologies), Tigran Rostomyan (Founder, AML Incubator), and Trisha Paguyo (Head of Business & Corporate Development, integrate.ai). Each letter attested to measurable, dollar- and percentage-based outcomes tied directly to Buzaladze's individual technical leadership. The petition was filed on April 2, 2026 with USCIS's Texas Service Center under premium processing.
Navigating the request for evidence
Unfortunately, not every case can be a slam-dunk approval. RFEs are tough, but occasionally they happen. Responding to an RFE is critical, and one of the reasons having a seasoned and experienced attorney matters.
In this case, USCIS issued a RFE, accepting two of the four argued criteria outright: critical/essential capacity and published material. They requested further proof of original contributions and high salary. Because the RFE conceded half the criteria, our team read it as a strong signal that the case was headed toward approval, needing only one additional category to succeed. With dYdX's U.S. launch timeline creating real time pressure, the team and Buzaladze made a deliberate strategic call: concentrate the response on the high-salary criterion, which could be strengthened quickly and reliably by benchmarking his verified pay stubs against Canadian software engineer salaries rather than U.S. ones. This is a comparison that favored him given lower prevailing wages in Canada. A lighter, secondary argument on original contributions was included to hedge risk, and the response was prepared and filed within roughly two weeks of the RFE.
Outcome
The O-1A was approved.
Buzaladze is now authorized to work in the United States as Senior Software Engineer for dYdX Trading Inc., where he leads architecture and optimization work across the company's trading systems, transaction processing frameworks, execution engines, and blockchain integrations — supporting dYdX's continued growth as one of the world's leading decentralized cryptocurrency exchanges.
