Alexander Skidanov is a Russian-born software engineer and entrepreneur best known as a co-founder of NEAR Protocol, a proof-of-stake blockchain built around sharding to keep transactions fast and inexpensive. Before entering the blockchain industry he was the first engineer hired at the database company MemSQL, now SingleStore, where he rose to director of engineering, and earlier he worked as a developer at Microsoft. A decorated competitive programmer who reached the ICPC World Finals as a student in Russia, Skidanov has spent his career on one recurring problem: how to make distributed systems scale.
Early Life and Education
Alexander Skidanov was born in Russia and grew up during the years when the country's strong tradition of mathematics education was producing a remarkable generation of programmers. Like many of his peers, he came to computer science through algorithmic problem solving, the discipline of writing correct, efficient code under time pressure that Russian universities cultivated with particular intensity [1].
He pursued his higher education in computer science in Russia, and it was there that his talent for algorithms became visible beyond the classroom. Profiles of Skidanov consistently point to his university years as the period that shaped his later career, since the competitive programming circuit he entered as a student functioned as both training ground and talent pipeline for the global software industry [1][2].
Anyone asking who was Alexander Skidanov before NEAR Protocol finds the answer in this formative period: a student absorbed in contests, data structures, and the mathematics of computation, long before blockchains existed.
Competitive Programming
Skidanov made his name in the International Collegiate Programming Contest, commonly known as the ICPC, the oldest and most prestigious team programming championship in the world. Teams of three students race to solve algorithmic problems over five hours, and only a small fraction of the tens of thousands of participants worldwide reach the World Finals each year [3].
Competing for his Russian university, Skidanov reached the ICPC World Finals and earned medal honors, an achievement that placed him among the strongest student programmers of his generation [1][2]. Russian teams dominated the contest throughout the 2000s, and emerging from that environment with a medal signaled an unusual level of ability.
The experience left a lasting mark on his engineering style. Colleagues and interviewers have noted that his approach to systems design reflects the contest programmer's habits: careful attention to algorithmic complexity, a preference for measuring rather than guessing, and comfort with problems that have no obvious solution [2]. Among notable Alexander Skidanov facts, his contest pedigree remains one of the most frequently cited.
Microsoft and MemSQL
Skidanov began his professional career at Microsoft, joining the company as a software developer in 2009. The move from contest programming to industrial software engineering at one of the world's largest technology companies gave him his first experience with code that had to survive contact with millions of users [1][2].
In 2011 he left Microsoft to become the first engineer at MemSQL, a San Francisco startup building a distributed, memory-optimized relational database. The company, later renamed SingleStore, set out to prove that a SQL database could deliver the speed of in-memory processing while scaling horizontally across many machines [4]. As employee number one on the engineering side, Skidanov worked on the core of the product, including query execution and the distributed systems machinery that let the database shard data across a cluster [1][2].
He spent roughly five years at MemSQL and rose to director of engineering, helping grow the team and ship a commercial product used by large enterprises [2]. The years he spent making a sharded database fast and reliable turned out to be direct preparation for his next act, since the central technical bet of NEAR Protocol would also rest on sharding.
Founding NEAR
In 2017 Skidanov teamed up with Illia Polosukhin, a former Google researcher and one of the co-authors of the influential Transformer paper in machine learning, to start a company called NEAR.AI. Their original goal had nothing to do with blockchains: they wanted to teach machines to write code from human descriptions, a research problem known as program synthesis [1][5].
The project joined the Y Combinator accelerator, but the founders ran into a practical obstacle. While exploring ways to pay contributors around the world who were labeling training data, they examined existing blockchain platforms and concluded that none could handle the throughput their use case required at a reasonable cost [1][5]. Rather than wait for someone else to solve the problem, they pivoted in 2018 and began building their own blockchain, the NEAR Protocol.
The decision drew directly on Skidanov's database background. NEAR's core design, a proof-of-stake network that shards its state and processing across many validator nodes through an approach the team named Nightshade, treats a blockchain much like a distributed database that must scale as demand grows [5][6]. The NEAR mainnet went on to launch in 2020 and grew into one of the significant layer-one platforms in the industry, with its own developer ecosystem, token, and governing foundation [6].
Work at NEAR and Return to AI
Within NEAR, Skidanov took responsibility for much of the protocol's technical direction while Polosukhin focused on ecosystem and outreach. He wrote and spoke extensively about sharding, consensus, and the engineering trade-offs of scaling a blockchain, and his explanatory posts on Nightshade and cross-shard communication became reference reading for developers studying NEAR's architecture [5][6].
Among Alexander Skidanov achievements at the company, the design and delivery of NEAR's sharded architecture ranks first. Sharding a blockchain is harder than sharding a conventional database because every shard must remain secure against adversarial validators, and NEAR was one of the first major networks to run sharding in production rather than leave it on a roadmap [5][6].
As the protocol matured, Skidanov returned to the founders' original interest. He refocused on NEAR.AI, reviving the goal of AI systems that can write software, this time in the era of large language models and with the accumulated resources of the NEAR ecosystem behind the effort [1]. The arc gives his career an unusual symmetry: an AI startup that built a blockchain out of necessity, and a blockchain founder who went back to finish the AI problem he started with.
Personal Life and Legacy
Skidanov has been based in the San Francisco Bay Area for most of his career in the United States, and he takes part in the founder community there, including involvement with Orange DAO, a collective of Y Combinator alumni that backs cryptocurrency startups [2]. He maintains a public presence through technical writing, conference talks, and podcast appearances rather than through celebrity, and he is generally regarded as one of the more engineering-minded figures among blockchain founders.
Any fair reading of the Alexander Skidanov biography places him within a specific lineage: the competitive programmers of the former Soviet world who moved into Silicon Valley infrastructure engineering and then into open blockchain networks. His influence runs through the systems he built, from the query engine of an enterprise database to the sharded runtime of a public network that processes transactions for users who will never know his name [4][6].
His career is still in progress, so his final legacy remains unwritten. What can already be said is that NEAR Protocol demonstrated that sharding, long dismissed as too complicated for blockchains, could work on a live network with real value at stake, and that demonstration owes much to a database engineer who had already spent years learning how to split data across machines without losing it [5][6].
