Senior Gameplay Engineer specializing in Unity/Unreal AR/VR experiences

Victoria, Canada20y exp

“Unity/C# engineer who owned an end-to-end real-time 3D product configurator at PictureThis3D, emphasizing modular data-driven architecture for performance and stability (including improved model download time and faster content updates). Also implemented on-device LLM/voice-command processing using small local models (e.g., Qwen 3.5 0.8B) and shipped Photon multiplayer systems with robust match-start/state handling.”

Junior Data Engineer specializing in Azure, CRM data pipelines, and marketing personalization

Hyderabad, India2y exp

“LLM/AI engineer who has deployed production RAG conversational analytics and Text-to-SQL systems over Snowflake and curated data marts, emphasizing enterprise-grade guardrails for accuracy, security, and cost. Notable for a structured approach to reducing hallucinations (curated metric/table registry, SQL validation, RBAC, and citation-backed responses) and for building resilient, observable multi-step agent workflows using LangChain/LlamaIndex and Airflow.”

“Backend engineer who rebuilt and refactored high-traffic systems at Phenom using Java/Spring Boot/Play and also designs Python/FastAPI services. Focused on measurable reliability and performance gains through DB/query optimization, async processing, and strong observability, with disciplined rollout practices (feature flags, parallel runs, rollback) and security patterns including token auth and row-level security.”

“Built and productionized an LLM-enhanced version of the WeDAA platform to auto-generate microservice architecture diagrams and support code generation from user prompts, including a practical solution for non-overlapping canvas object placement via coordinate templates. Experienced in diagnosing agentic workflow failures using AWS Strands agents with feature-flagged debug logging, and frequently supports sales through tailored demos and POCs to drive adoption.”

“Full-stack/product-leaning engineer in logistics and high-traffic portals who ships production AI features: built an AI-assisted shipment status Q&A system using Pinecone + GPT-4 and a high-volume Python ingestion pipeline (500K+ records/day), delivering 35% fewer support tickets and cutting resolution time from 11 to 4 minutes. Also led a legacy Angular-to-React/TypeScript rebuild that boosted Lighthouse performance from 60 to 90, and has hands-on AWS EKS operations experience including resolving a 3x traffic scaling incident.”

“Full-stack engineer who has delivered production customer analytics/dashboard features using Next.js App Router + TypeScript on the frontend and Java Spring Boot microservices on the backend. Demonstrates strong production ownership (monitoring latency/error rates/adoption) plus hands-on performance work across React rendering and Postgres query/index optimization, and has implemented Temporal-like durable workflows with retries and idempotency.”

“Contingency recruiter specializing in AI and data roles, currently managing 15 live requisitions across 6 clients (consultancies and financial institutions). Uses a structured, color-coded Google Sheets system to track pipeline stages and notes, and reports a typical 2-week turnaround from intake to placement.”

Junior AI Data Engineer specializing in Azure Databricks lakehouse and GenAI RAG systems

Irving, TX2y exp

“Backend/applied AI engineer from Cloud Rack Systems who built production GenAI/RAG and data platforms on Azure/Databricks at enterprise scale (2.5M records/day). Known for making LLM systems behave like deterministic services via strict retrieval contracts, citation-based validation, and strong observability—shipping a knowledge assistant used daily by 50+ users while driving hallucinations near zero and materially improving latency and cost.”

Junior Software Engineer specializing in full-stack and AI systems

Arizona, USA3y exp

“Backend engineer with experience stabilizing data processing/analytics pipelines and refactoring brittle backend APIs. Has hands-on FastAPI work emphasizing strong validation (Pydantic), clear layering, and secure JWT-based auth with role/row-level controls, plus pragmatic migration tactics like parallel runs to protect data integrity.”

Junior Full-Stack Software Engineer specializing in React, Node.js, AWS, and Generative AI

3y exp

“Built and production-deployed a Streamlit-based PDF RAG chatbot using LangChain (FAISS, embeddings, prompt templates) and OpenAI, optimizing Streamlit’s stateless behavior by caching vector DB + chat history to cut latency and API cost. Demonstrates a rigorous evaluation mindset (gold datasets, unit tests, LLM-as-judge, groundedness KPIs) and has experience communicating privacy/accuracy safeguards (RBAC, data masking, citations) to a non-technical client at Kalven Technologies.”

Junior Full-Stack Software Engineer specializing in mobile, cloud, and GenAI integration

Syracuse, NY2y exp

“Software engineering intern with hands-on ownership of a Java/Spring Boot order management microservice, including production performance tuning via Redis caching and database indexing driven by API logs/metrics. Also contributed to a production mobile-backend LLM feature using RAG with embeddings over structured data and documents (DB + object storage), with guardrails to keep responses grounded.”

“Indie/solo Unity C# developer who shipped a VR game (Elysium Trials) across Meta Quest, SteamVR, and Pico, including a high-performance cross-platform leaderboard system with sub-second score retrieval. Also built a recent multi-agent AI puzzle project where multiple AI bots communicate via JSON and uses UX techniques to mask LLM latency; has shipped additional mobile titles and focuses heavily on optimization and immersive VR UI.”

“Backend Python engineer who owned the full backend build of an AI-driven platform for UK golf clubs, including FastAPI microservices, vector search, and a tuned LangChain+Pinecone RAG pipeline focused on cost and hallucination reduction. Experienced deploying Django/FastAPI/Flask stacks on AWS-backed Kubernetes with GitOps/ArgoCD-style delivery, plus executing legacy-to-AWS migrations and building Kafka-based real-time analytics pipelines.”
