Hey there, I'm Sameer Ray,
AI Engineer & Automation Specialist
AI Engineer & Automation Specialist
Paid consulting, AI agent builds, and training — based on what I've actually shipped, not theory.
Stuck on an existing system, or scoping a new one? Bring architecture decisions, debugging sessions, or "should I even build this" calls — full-stack, AI/RAG pipelines, or infra (AWS, Postgres, Redis).
Rate: contact for rate
1:1 or small-cohort paid training on building real agentic systems — tool use, orchestration, RAG grounding, failure/retry handling — drawn from building a 7,100-line multi-agent system (NexMesh) and production RAG on ShikshaHub.
Rate: contact for rate
Send a repo or a design doc, get a written review — correctness, security, scaling risk, and what I'd change first. No call required.

Payment via Wise or Payoneer, invoiced after the call/scope is confirmed.
Technical setup and launch of the website for KATHA Studio, a brand studio in Kathmandu. I handled hosting configuration and deployment on cPanel, domain mapping and DNS, HTTPS/SSL setup, and troubleshooting of access and deployment issues.

A distributed background-job system built from scratch — Fastify, BullMQ, Postgres, and Redis. Includes a custom Redis-backed distributed semaphore that keeps concurrency and rate limits genuinely global across multiple worker processes, load-tested and verified rather than assumed correct.

A real-time telemetry platform on AWS — full network topology (VPC, private subnets, ALB) provisioned with Terraform, containerized services on ECS Fargate across multiple Availability Zones, and ElastiCache Redis as a Multi-AZ Pub/Sub broker for WebSocket message distribution.

A bilingual EdTech platform I built and run, with a full retrieval-augmented Q&A feature layered on top of the course content — pgvector embedding store, OpenAI embeddings, Groq-based grounded generation.

An EdTech SaaS platform I architected and built solo — enrollment, payments, roadmap delivery, and certification — that grew to 1,274+ registered students, backed by an AI pipeline that deduplicated over 3,600 duplicate records across the project database.

A 7,100-line distributed multi-agent orchestration system — autonomous agents coordinating over a message-passing layer, each with independent failure and retry handling.

A language model trained from scratch on a 528K-row Devanagari dataset. Published two open datasets on Hugging Face (176K and 352K rows, Apache 2.0) to support further Nepali-language AI work.

Freelance, Kathmandu
Configured hosting, DNS and SSL and deployed the studio's website on cPanel, then resolved the access issues that came up. Reference letter available on request.
Contract, Remote
Evaluated AI-generated code across Python, TypeScript, C#, and Flutter against a rubric-based 1–5 quality scale, including side-by-side model comparison and hallucination-rate benchmarking.
Self-employed
Architected and built a virtual-internship EdTech platform from scratch — enrollment, payments, roadmap delivery, certification — reaching 1,274+ registered students.
Enterprise 360, Kathmandu
Built Python data pipelines and GIS-based network-planning tooling, cutting a manual 2-hour wireless coverage-point planning process down to roughly 45 minutes.
TypeScript, JavaScript, Python, SQL
React, Next.js
Node.js, Fastify, Express, FastAPI
PostgreSQL, Redis, Docker, AWS, Terraform
RAG, LLM evaluation, pgvector, Groq, OpenAI
Open to full-time roles, contract work, and interesting things to build. Based in Kathmandu, open to remote, hybrid, or relocation with sponsorship.
