• Quant employment verification: CONFIRMED. LinkedIn public profile (sg.linkedin.com/in/aldrianobaja) lists DBS Bank, Singapore, Feb 2024 - Oct 2024 (9 months) in his experience, matching the caller's unverified lead (DBS Bank 'Quant App Developer', 2024-02 to 2024-10) and the people-index entry. The role is PAST, not current (current role is Lecturer at Singapore Polytechnic). DBS Bank is a Singapore bank whose Global Financial Markets (GFM) unit runs a front-office quant developer team that 'designs and develops quantitative trading systems and pricing engines' for the FICC+EQ business, so DBS qualifies as a quantitative-finance employer. Caveat: the title and dates rest on the self-reported LinkedIn profile (the index mirrors it), not an independent DBS source; identity is supported (name, education and other employers align), but the exact 'Quant App Developer' title is self-reported/LinkedIn-level.Feb 2024
• Current role: Lecturer on Applied AI & Analytics, School of Computing, Singapore Polytechnic (alphaXiv and the LinkedIn headline both state this), i.e. a teaching role, not a quant role - the DBS quant job is a 9-month past stint, not current employment.2025
• DBS Bank operates a quantitative finance function: its Global Financial Markets (GFM) front-office quant developer team designs quantitative trading systems and pricing engines supporting the FICC+EQ business, which is why the DBS role classifies as a quantitative-finance position rather than a generic bank software job.2024
• Recent teaching output: built 'SoC DataForge', a Singapore Polytechnic Devpost project providing lecturers a web tool to generate scenario-based data-science assignments with unique-but-fair per-student datasets, aimed at the new 'Quantitative Foundations of AI' module in the DAAA curriculum - showing the current role is hands-on course/assessment tooling.2025
• Industry path after CMU: Senior Data Scientist at Traveloka (Oct 2019 - Jun 2020), then Senior Data Scientist (Mechanism Design) at Sembly Inc. (Jul 2020 onward at time of CV) - both NLP/data roles, neither in finance.Jul 2020
• Master of Language Technology, Carnegie Mellon University Language Technology Institute (advisor Teruko Mitamura); LTI alumni listing shows the degree conferred 2020, with contact [contact omitted].2020
• Undergraduate degree: Bachelor of Computing (Computer Science, First Class Honours), NUS, Jul 2009 - Jul 2013, minor in Mathematics; Lijen Industrial Development Award (second top student in the batch) and Dean's List for four semesters.Jul 2013
• His stated interest is teaching (tertiary students) and research in NLP/generation, and he was 'considering to do PhD to better qualify myself for teaching positions' - i.e. the teaching role is aligned with a long-standing stated preference, not a recent pivot.2020
• Public contact email [contact omitted] and personal site justhalf.github.io appear in his own CV, published by him.2019
• Taught CS1231 Discrete Structures and lab courses CS1020/IT1006 at NUS (2011-2012) and TA'd CMU 11-711 Algorithms for NLP (Fall 2018), delivering a lecture on Conditional Random Fields - an early and continuing teaching thread that precedes the current lecturer role.Dec 2018
• NLP publication record with long papers at ACL 2017 (MalwareTextDB), EMNLP 2016 (discontiguous entities) and 2017 (overlapping mentions), NAACL 2016, COLING 2018, and AAAI 2017, several with advisor Wei Lu at SUTD; DBLP author page lists the full record.Aug 2018
• Research Assistant at SUTD (Jul 2015 - Jun 2017) under Asst. Prof. Wei Lu, and Research Engineer at Knorex (Jul 2013 - Jun 2015) - the pre-master's technical research track.Jun 2017
