“Software engineer actively using AI-first development workflows, including Cursor, prompt engineering, and multi-agent setups, to dramatically compress development time. Most notably, they say they built a Regression Optimizer product end-to-end from scratch and used multi-agent approaches to improve troubleshooting and response quality.”

“Early engineering hire at The Coaching Market (B2B2C e-learning startup) who owned re-engineering core REST APIs (FastAPI) and shipping an enhanced Next.js UI, plus automating most deployments via CircleCI/Vercel. Strong in data-driven iteration (surveys/Jira/Slack + Google Analytics, A/B tests) and reliability/performance improvements with measurable impact (30% less downtime, 40% faster releases, 25% faster loads).”

“Frontend lead on a campaign management platform, owning architecture and delivery in Next.js (App Router) with TypeScript types derived from Swagger contracts and Zustand state management. Built and shipped complex, form-heavy multi-step flows like QR code creation with live preview/analytics considerations, and improved maintainability by extracting shared table/filter abstractions while proactively defining UX edge states with design.”

“Full-stack engineer with experience delivering an end-to-end NIH application using Angular and scalable .NET Core microservices backed by MySQL. Has hands-on depth in complex approval/workflow implementations (RBAC + workflow engine) and performance tuning for million-record, data-driven systems, plus 5 years with Java/Spring Boot microservices and React.”

“Full-stack engineer focused on AI-powered products who has independently built end-to-end systems ranging from a food delivery platform with admin/rider workflows and payments to RAG-based LLM apps like a PDF-to-chat book assistant. Particularly interesting for teams building production AI because they speak concretely about retrieval architecture, evals, observability, fallback design, and human-in-the-loop decisions in customer support use cases.”

“Unity developer with hands-on experience evolving enemy AI from event-driven logic to FSMs and ultimately behavior trees, improving both performance and debuggability while making enemy reactions feel faster and more consistent to players. Has built multiple multiplayer games using Photon PUN 2 and Unity NetCode, focusing on server-authoritative synchronization and minimizing network traffic; also applies AI tools to accelerate prototyping and diagnose complex issues like OPC UA tag mismatches.”

“Unity developer who has published multiple games (e.g., "Hole people", "beads out") and reports building nearly everything inside the games himself, including gameplay, remote config, and A/B testing. Also built "Age of battles PvP" with backend server, economy, multiplayer, analytics, and blockchain/Web3/NFT functionality, including custom verification logic to mitigate third-party transaction delays. Currently earning about $3,000/month due to covering both backend and Unity/multiplayer responsibilities.”

“Robotics-focused engineer with hands-on experience building a lab robotic arm, combining software engineering with circuit design and hardware integration (DC motors, Raspberry Pi, gamepad control). Has worked on mapping (GMapping) debugging and implemented MQTT-based communication between Raspberry Pi and ESP32, plus used MATLAB/Simulink to simulate STM32 behavior for system-level testing.”
