“Built and shipped a production LLM hallucination detection and monitoring pipeline using semantic-level entropy (embedding-clustered multi-generation variance) to flag unreliable outputs in downstream automation. Implemented a scalable async architecture (FastAPI + Docker + Redis/Celery) with strong observability (structured logs + PostgreSQL) and developed evaluation loops combining controlled prompts and human review; also partnered with non-technical stakeholders on AI-driven form validation/document processing.”

Melbourne, FL11y exp

“Game developer with a distinctive niche in integrating LLM-driven dialogue directly into Unity gameplay, including a full web-hosted architecture using llama.cpp, FastAPI, and cloud GPUs for real-time NPC interaction. Also brings VR/mobile optimization experience from a drone simulation project at GovScio, combining AI systems thinking with practical 3D environment and performance work.”

“Backend-leaning fintech engineer who led a small pre-seed team building cross-border remittance and payment API products. Brings a mix of technical leadership, customer-facing product discovery, and hands-on experience with scalable payment infrastructure, compliance integrations, and cloud deployment on AWS.”

“Built and owned the core execution pipeline for Drona, an AI code grading platform, spanning Next.js frontend, real-time WebSocket updates, Celery/Redis async processing, Docker sandboxing, and PostgreSQL persistence. Particularly strong in backend reliability and architecture, with concrete wins including reducing API response time from about 5 seconds to 200 ms and eliminating silent job failures in production.”

“IBM Power/AIX engineer who has owned a large production estate (20+ Power9/Power10 frames and 400+ LPARs) with vHMC and dual-VIOS HA. Has hands-on incident recovery experience (NPIV/RMC issues, LPM restores) and PowerHA failovers, plus modern DevOps exposure using Terraform on AWS and CI/CD with GitHub Actions/Jenkins (including deploying AI/RAG and vision workloads).”

“Frontend developer (~2 years experience) who has built user-tier-based UI logic (BannerRotator) and shipped a KYC workflow in a fast-paced, regulated crypto/e-commerce context. Emphasizes modular React + TypeScript patterns, scenario-driven QA documentation in Notion, and codebase modernization (TypeScript rewrites and legacy hook updates).”

“Data engineer focused on building reliable, production-grade pipelines and data services end-to-end, including a 50+ GB/day pipeline ingesting from APIs/files into Snowflake with PySpark/SQL transformations. Emphasizes strong data quality controls, monitoring/retries, and performance optimization, and has also shipped a Python data API with caching and backward-compatible versioning.”

“Frontend-focused developer who built Butterfly Booking, a live two-sided salon scheduling platform for both business owners and customers. Demonstrated strong ownership across UI architecture, AWS deployment, responsive design, and a mid-project database migration, with results including a successful replacement of Vagaro, over $3,000 in annual savings for the client, and roughly 20% growth in bookings after launch.”

“Full-stack/backend-focused engineer who built and architected dribolission.com, a SaaS school management platform used by 10+ schools and thousands of students. He has practical production experience with NestJS, React, MongoDB, Redis, Nginx, and Stripe, including redesigning payment architecture for 3DS support and handling transaction reliability in a live system.”
