I am a senior full-stack and infrastructure engineer, available for part-time contract work at 20 to 25 hours a week. I am based in India and already work US-overlapping hours. Rate: $35 to $50 per hour depending on scope, minimum engagement one week. What I do day to day: I own production infrastructure for a multi-tenant AI platform handling 10M+ events a day across 300,000+ sub-accounts. That includes the event-processing runtime (40+ concurrent work queues on a Redis-compatible cluster, autoscaled on queue depth rather than CPU, load-verified at 1,000 requests per second), the entire AWS footprint codified in Terraform, and a ClickHouse and Grafana observability stack I built from scratch. Before going solo I led a 14-engineer team at a software agency across a 10-client portfolio. Things I have built and run myself: Lumbox (lumbox.co), live with paying customers. It gives an AI agent a real mailbox, a browser session and an encrypted credential vault behind one API key, plus an MCP server published on npm. I self-administer the whole Linux stack behind it: Haraka SMTP, Dovecot IMAP, Caddy, SPF/DKIM/DMARC and outbound deliverability. BlockWill (blockwill.io), a digital estate platform live on web, iOS and Android from one Next.js codebase, with passkey-derived vault encryption and subscription billing. A video pipeline that records live streams, transcribes them, selects clips with an LLM behind a review gate, and renders captioned vertical video. 4,600+ clips produced on a single CPU-only box with no GPU. AgentCursor (github.com/kumard3/agentcursor), MIT licensed, a computer-use MCP server for AI agents. Stack: TypeScript, Node, Next.js, React, React Native, Python, Rust, Postgres, Redis, Docker, Terraform, AWS, Cloudflare Workers/D1/R2, ffmpeg, speech-to-text, and LLM work including RAG, MCP, evals and tracing. Best fits: taking a prototype to production, rescuing a stalled or inherited codebase, cutting infrastructure cost, building LLM and agent features that have to survive real traffic, email and deliverability infrastructure, and video or audio pipelines. PM me with what you are building and I will tell you straight whether I am the right person for it. If I am not, I will say so. Kumar   submitted by   /u/kumard3 [link]   [comments]
