Vetted API Development Professionals

“AI/software engineer with hands-on experience deploying an LLM-powered quiz generation platform for students, integrating Python services with Gemini APIs plus frontend and database components. Emphasizes production-grade reliability through observability, schema validation, async processing, and performance tuning under high concurrency, and has collaborated with product/operators (e.g., at Colombo AI) to translate real-world constraints into scalable technical solutions.”

“Unity developer with shipped Meta Quest experience who owned the full lifecycle from architecture and feature development through builds and store compliance. Demonstrated strong performance optimization skills (profiling in Unity and MQDH, optimizing textures and render layering) and has built and shipped a modular, cross-platform puzzle game (PC/web/mobile).”

“Frontend team lead who delivered an ArcMap React + TypeScript product end-to-end, emphasizing Atomic Design-based design systems, reusable component architecture, and performance optimizations (code-splitting/lazy loading, server-side fetching, webpack). Adopted React Query over Redux with centralized query-key management and coached the team on its usage while shipping quickly in a high-velocity environment.”

“Product-minded full-stack engineer with hospitality tech experience who owned and scaled a multi-region guest verification/check-in workflow (ID/passport scanning, OCR, and government submissions) and built internal tools that cut manual entry up to 80%. Also built a React/TypeScript + FastAPI RAG “second brain” with async ingestion workers and an event-driven e-folio email microservice hardened with idempotency and retries.”

“Backend/DevOps-leaning engineer who has owned a Python serverless platform on AWS (Lambda, DynamoDB, Step Functions), including complex multi-step business workflows with transaction-based consistency and robust failure handling. Also supported an on-prem SQL to Azure Data Lake migration by building and monitoring Python + Azure Data Factory ETL pipelines, and led GitOps-style CI/CD automation with GitHub Actions (tests, security scans, automated deployments).”

“Marketing Director-level CRM/lifecycle marketer with deep restaurant/franchise and DTC experience, known for using CDP-driven segmentation and local-store personalization to materially lift loyalty (18% to 30%) and shift visit frequency (60% monthly-to-weekly). Comfortable integrating data across POS/CRM/email/feedback systems via APIs and running continuous A/B testing, plus strong stakeholder management to win franchisor buy-in through pilots and measurable outcomes.”

“Software engineer (Lance Soft Engineering) who built a Java/gRPC real-time request tracking system supporting ~20K simultaneous requests, using Kafka event streaming and PostgreSQL to improve transparency and cut support requests by 35%. Demonstrates strong production operations skills—resolved live latency spikes with Kafka async messaging (+48% throughput) and executed safe migrations using parallel runs, staging validation, and blue-green deployments.”

“VR multiplayer Unity developer who implemented high-impact interaction systems (notably a math-driven, physics-aware door system with audio occlusion and culling) and designed/built a fully custom cross-platform multiplayer stack from scratch using KCP, WebSockets, WebRTC, and MemoryPack—plus recording, NPC support, and backward-compatible client modes for an educational/learning platform.”
