Akshat Lakhera — software engineer building systems where the hard parts matter: latency, correctness, scale, and reasoning.

Shipped a production gamified campus-ambassador platform for 100+ users — dual student and admin portals, live leaderboards, and 20+ REST APIs in TypeScript and Next.js on a 17-table Supabase (PostgreSQL) schema, delivered across Agile sprint cycles. Eliminated concurrency defects under peak load with atomic transactions and row-level locking, enforced secure coding through input validation and parameterized queries, and gated every release behind 433 automated tests across 21 suites.

Accelerated the explicit Black-Scholes PDE solver ~10× on multicore CPUs with OpenMP — persistent thread teams, cache-friendly access patterns — and scaled it across nodes with MPI using domain decomposition and ghost-cell exchange, benchmarked against a serial baseline. Implemented and benchmarked Explicit, Implicit, and Crank-Nicolson finite-difference solvers in C++ and Python against analytic prices; exploiting Crank-Nicolson's unconditional stability cut average solve time from 2.69 seconds to ~6 milliseconds at equal-or-better accuracy.

Engineered Kafka-based asynchronous communication between Java Spring Boot and C++ microservices over TCP/IP in a distributed, mission-critical defense system — improving processing efficiency by 60%. Trained a YOLOv8 maritime vessel-detection model on HRSC2016 satellite imagery to 0.83 mAP@0.5 via systematic preprocessing and a custom XML-to-YOLO annotation parser, and streamlined C++ Linux service deployments into a CI/CD pipeline, eliminating manual integration errors across test environments.
