Backend Engineer @Osfin.ai | Distributed Systems | ETL

About

I build the backend systems that keep financial transactions from falling apart. I'm a Software Engineer at Osfin.ai, a fintech infrastructure company in Bengaluru, where I work on reconciliation engines, ETL pipelines, fund movement rails, and core banking workflows, systems that process millions of transactions daily across UPI, IMPS and NEFT. In the last year, I've shipped things that actually matter in production: → Built the Input Board module, automated file intake from S3 & UI using config-driven validation and SQL*Loader ingestion, replacing a manual process across GL, reconciliation, and fund movement workflows. → Designed the Organisation Data feature, centralized business config across 6+ core banking modules, eliminating redundant module-level handling platform-wide. → Raised test coverage from 23% to 97%, migrated 12+ raw SQL statements to SafeQuery abstractions, and resolved 6+ VAPT and code-scanning security findings across Backend, Batch, and RIM repositories. Outside work: IEEE NSUT Vice President (grew chapter from 200 → 700+ members), Dr. J.K. Pal Award winner (IEEE Delhi Section, 2025), and co-author of an IEEE-published paper on GRU-ACO energy routing in DC nanogrids. I'm looking for backend, distributed systems, or data infrastructure roles where I can own hard problems and grow into a deeply technical engineer. github.com/abhimanyu0x

Work experience

Software Engineer at Osfin.ai, Jul 2025 - Present · 1 yr 2 mos, - Engineered the Input Board module — automated file intake from UI & Amazon S3 using config-driven matching, validation, and SQL*Loader ingestion, replacing a manual process across reconciliation, GL, fund movement, and voucher settlement workflows and improving reliability at scale. - Designed the Organisation Data feature — centralized shared business configuration across 6+ core banking modules (fund movement, GL generation, snapshot, freeze, currency conversion), eliminating redundant module-level handling and reducing cross-module inconsistencies platform-wide. - Contributed to backend systems supporting millions of daily transactions across UPI, NEFT, and IMPS, spanning pan-India branch, ATM, and endpoint reconciliation workflows.

Software Engineer Intern at Osfin.ai, Jan 2025 - Jul 2025 · 7 mos, - Refactored legacy tests and introduced reusable test data builders (generators), increasing automated test coverage from 23% to 97% — making the test suite significantly more stable and extensible. - Migrated 12+ raw SQL statements to parameterized SafeQuery abstractions across 2 backend modules, improving query safety, maintainability, and alignment with backend engineering standards. - Resolved 6+ security findings from static code scanning, image scanning, and VAPT across Backend, Batch, and RIM (Recon In Memory) repositories, strengthening release readiness for sensitive financial workflows. - Implemented 5+ configurable fund-movement rules and transaction-report download capabilities, improving operational control and backend support for reporting workflows.

Software Engineer Intern at Legitifed, May 2024 - Jul 2024 · 3 mos, Michigan, United States, - Built a Solidity smart contract on Ethereum to automate patient consent management for medical data sharing — enforcing on-chain access control and reducing manual consent overhead for healthcare providers. - Designed REST APIs enabling healthcare providers to integrate secure, consent-gated patient data transfers into existing systems, with detailed documentation that streamlined onboarding and reduced maintenance overhead. - Delivered fully remote within a 3-month timeline, collaborating across time zones with a US-based team — shipped all milestones on schedule.
