Nutan Prabhat

Sole engineer on the account — scoping, HLD/LLD design, development, testing, documentation, and delivery. Rebuilt a two-stage visual retrieval engine: CLIP ViT-B/16 embeddings in Qdrant for candidate recall, then a feature-based reranker for precision — Top-1 accuracy from a 41.9% baseline to 97.7%. Delivered a Python desktop CAD validation platform end to end — DXF parsing, 2D computational geometry, spatial indexing, PySide6 UI — with one-click batch processing across drawing folders.

Built and published Pen Fight 2D, a turn-based multiplayer mobile game in Unity (C#), reaching 10K+ downloads on Google Play. Integrated Google Cloud Platform (Authentication, APIs, Analytics) and Unity Cloud Save. Built a server-authoritative economy in Node.js with escrow-held fees, idempotent payouts keyed by match ID, dual-client verification, and refund handling. Ran the full release cycle: internal testing tracks, feedback-driven fixes, production rollout, and post-release updates.

Primary code reviewer within a year of joining; requested changes on 25+ of 50+ PRs, including work already approved by senior staff. Delivered 5 client-specific and 2 core-team features end to end; 2 were adopted into the core product. Designed a localization abstraction layer: providers switchable through configuration, per-element opt-out control, and coverage extended through API and database layers. Diagnosed and optimised SQL queries that had degraded 2–3x, restoring near-baseline response times.
