Aleksandar Šušnjar

Platform engineering and architecture leader with 25+ years building mission-critical search, data, security, and cloud platforms across global enterprises and startups. I pair deep, hands-on architecture with engineering leadership: setting technical direction and standards, then making teams faster and more predictable. Most recently I make AI-assisted software development genuinely safe to ship, governed AI code generation, RAG, multi-agent review, conformance/model-based testing, and quality/security gates that raise throughput without sacrificing correctness or maintainability.What I do:• Architecture & platform: enterprise/solution architecture, distributed systems, event-driven design, GraphQL federation, API governance, secure-by-design (ABAC/RBAC).• Search & AI: semantic/vector/full-text search, retrieval-augmented generation (RAG), knowledge graphs, query planning/orchestration, LLM integration at petabyte scale.• Engineering leadership: globally distributed teams,

• Quant employment verification: NOT CONFIRMED. A full-career sweep of his public record shows no role at any quantitative investment, trading, market-making, hedge-fund, or systematic/algorithmic trading firm. His 25+ year engineering trajectory runs through enterprise software: Planet Intra (intranet software, 1998-2001), Hummingbird Ltd (document management, 2001-2006), Infor/Workbrain (workforce management, 2006-2008), BlackBerry (endpoint management, 2009-2018), BlueCat (IP address management, 2018-2022), Nuvalence consulting (Ford Credit engagement, 2022-2023), Leap Tools (AR home-renovation SaaS, 2023-2025) and Autodesk (search platform, 2025-). No bank, asset manager, energy or crypto trading desk appears. The caller's quant lead traced to a same-name-but-different company (quantlabs.rs), not to this person.Sep 2026
• Employer-classification check: the 'Hummingbird' on his 2001-2006 role was Hummingbird Ltd, a Toronto enterprise content/document-management software vendor (NASDAQ:HUMC) acquired by Open Text in 2006 — NOT the Belgrade quantlabs.rs 'Hummingbird' market-data firm in the caller's lead. The caller's company record (domain quantlabs.rs) is a different company and does not match this role.Sep 2006
• Aleksandar Šušnjar represented Yugoslavia at the International Olympiad in Informatics (IOI) 1990; the Competitive Programming Hall of Fame standings page for IOI 1990 lists his name under Yugoslavia.Jul 1990
• Won a silver medal at IOI 1990 (Yugoslavia) with an absolute score of 98 and absolute rank 14/100; the IOI official statistics database and CPHoF both record the medal, and the IOI 1990 report lists the Yugoslavia delegation.Jul 1990
• Early career predates Canada: he lists 1991-1994 university-studies work (CS lab Novell network, teaching assistant, 'SoftSound' playout system) and 1994-1998 PC Press work (35 technology reviews plus benchmark code), a Serbian/Yugoslav-origin trajectory consistent with the IOI 1990 Yugoslavia competitor of the same name.1998
• Authored a public 'Comprehensive GraphQL Specification Proposal' on the Apollo GraphQL community forum (April 2025), positioning him in API-architecture/spec-design circles beyond his day job.Apr 2025
