case studies.
A closer look at recent builds — the problem, the approach, and the measured outcome.
Next.jsNode.jsTypeScriptDockerRedisLLM APIs
- Problem: Built an autonomous AI coding agent that plans, writes, tests, and debugs full development tasks end-to-end, cutting manual prompting for routine engineering work
- Tech Stack: Node.js, TypeScript, and LLM APIs power the agent's orchestration/reasoning layer, with Redis for session caching and a Next.js dashboard for live task tracking
- How It Works: Spins up isolated Docker containers per session to safely run and test AI-generated code, supporting 50+ concurrent sandboxes with GitHub integration and live demo previews
React.jsNode.jsTypeScriptPostgreSQLLLM APIs
- Built a unified AI gateway enabling developers to access multiple LLMs via a single API, reducing per-provider integration time by an estimated 60% for new users
- Designed REST API endpoints for prompt submission, model routing, and response streaming, supporting high-concurrency requests with consistent sub-200ms latency
- Implemented a dynamic provider abstraction layer, enabling zero-downtime model provider switches without any client-side code changes
- Developed a lightweight TypeScript SDK that cut developer onboarding time and reduced integration boilerplate by ~40%
Next.jsTypeScriptExpress.jsMongoDBDockerAWS
- Prevented concurrent booking conflicts and race conditions using atomic MongoDB operations and transaction-safe logic
- Reduced API calls by 40% through client-side debouncing, intelligent caching, and optimized client-server communication protocols
- Improved transaction throughput by 45% by designing efficient, failure-tolerant cancellation and rebooking workflows
- Cut page load time by 30% by integrating Cloudinary CDN for optimized image delivery and lazy loading
Next.jsTypeScriptSocket.IOExpress.jsMongoDB
- Built a real-time multi-user collaboration platform with bi-directional WebSocket sync, enabling teams of 5+ to edit simultaneously with zero data loss
- Reduced multi-user sync errors by 60% through granular event handling and delta-based state transformation, improving session reliability
- Implemented session-based authentication and RBAC, securing workspace access for multiple user roles and reducing unauthorized access incidents to zero
- Cut WebSocket payload size by 35% via binary compression and delta updates, improving performance by 2x on low-bandwidth connections
Have something similar in mind?
I take on a limited number of projects at a time, so timelines stay realistic and every client gets full attention.
