Alexandru Velea

Alexandru Velea is a Romanian software engineer. As a student he represented Romania at the International Olympiad in Informatics in 2014 and 2015, winning a Silver medal in 2015, and competed under the Codeforces handle alex.velea. He holds a Bachelor's degree in Computer Science from the University of Bucharest. His public GitHub profile (alexvelea) describes his focus as 'All things crypto-backend' and links to the Lighter/elliottech crypto proving project. LinkedIn/index data additionally lists software-engineering roles at Deepwaters (VatnFörn), Blink, Google, CS Academy, unnamed stealth startups, and a 2019 Software Engineer internship at Jane Street; apart from the Olympiad record and education these role claims rest on index/aggregator data and are not independently confirmed.

• Quant employment verification: UNRESOLVED. The only quantitative-finance-adjacent role in the evidence is a 'Software Engineer Intern at Jane Street' (2019-06 to 2019-09), which appears ONLY in index/LinkedIn enrichment data (an aggregator), with no independent primary-source confirmation from Jane Street or a dated public record; identity of the subject is supported (IOI 2014/2015 Romania, University of Bucharest CS, GitHub alexvelea in Romania with crypto-backend bio), but that supports WHO he is, not the Jane Street role. Jane Street is a genuine quantitative trading firm/market maker, so if the role were primary-source confirmed it would qualify - but on current evidence it does not meet the CONFIRMED bar. Other employers are NOT quant: Deepwaters/VatnFörn (crypto/blockchain trading infra), Blink (Bitcoin/Lightning wallet), Google (SRE), CS Academy (coding-education platform), and unnamed Stealth Startup(s). No internship, insight day, camp, scholarship, or incoming offer has been confirmed as an actual quant role.
• Index/LinkedIn enrichment (not primary-source confirmed) lists Software Engineer at Stealth Startup; past roles Software Engineer at VatnFörn (deepwaters), Lead Software Developer at Stealth Startup, Software Engineer Intern at Jane Street, Crypto Developer at Blink, Site Reliability Engineer at Google, Back End Developer at CS Academy; education Bachelor's CS, University of Bucharest.
• FULL CAREER (index/LinkedIn-derived, NOT independently confirmed): Software Engineer at Stealth Startup (current, undated); Software Engineer at VatnFörn (Deepwaters); Lead Software Developer at Stealth Startup; Software Engineer Intern at Jane Street (2019-06 to 2019-09); Crypto Developer at Blink; Site Reliability Engineer at Google; Back End Developer at CS Academy. Dates are not shown for most roles and are NOT filled here.
• Won Silver at IOI 2015 representing Romania (368.91 pts, rank 55/322 abs.); also competed at IOI 2014 (score 56). IOI statistics page lists him as a Romanian contestant.Jul 2015
• Jane Street (the 2019 internship employer in the index data) is a quantitative trading firm / market maker, which is why the lead matters for the quant question, but it appears only in index/LinkedIn data with no primary Jane Street page confirming the role.
• VatnFörn (Deepwaters) is a crypto/blockchain financial-infrastructure company (deepwaters.xyz), founded 2020-2021, HQ Delaware; it builds on-chain privacy/dark-pool style trading infrastructure, so it is crypto-finance rather than a traditional quant hedge fund, and no role dates are published for Velea there.2021
• GitHub alexvelea (uid 10797318), Romania, bio 'All things crypto-backend', member of org @elliottech, X @csVelea, 35 followers. Indicates a crypto-backend engineering focus.
• GitHub org membership @elliottech ties the alexvelea account to the Lighter project (elliottech/lighter-prover, a ZK proving system for a crypto exchange), consistent with a crypto-backend focus rather than traditional quant trading.
• LinkedIOI profile links a Codeforces account; competitive-programming identity @alex.velea (Codeforces) and CP Hall of Fame entry with ~$324 prize money confirm a Romanian competitive-programming record under this name.
