Portfolio v3.0 — 2026

Nivyan.AI Engineer & AWS Cloud Engineer

I build full-stack systems, LLM integrations, and cloud infrastructure that holds up — without paging anyone at 3am.

01 / About

I build things
at the edge of
what's possible.

I've been engineering software for six years — from solo freelance builds to leading delivery on multi-tenant SaaS. The throughline: building systems at the intersection of elegant code and real-world impact.

From LLM-powered tools and Retrieval-Augmented Generation pipelines to distributed AWS serverless backends, I work across the full stack with a bias toward infrastructure that scales — with production experience in React, TypeScript, Next.js, Python, FastAPI, LangChain, and cloud-native patterns built to outlive the demo.

Recent production work spans Promptly (a Socratic AI product architect where 16 metered agents propose and deterministic code decides — a four-gate cost guard, an acyclic dependency graph, a living PRD, all behind FastAPI + Anthropic Claude + Next.js), SBA Loans HQ (a multi-tenant SBA lending SaaS with four portal experiences from one codebase, a blind-listing deal marketplace, AWS Textract + Gemini document automation, and $33M+ in loans processed), and Quanta (a self-hosted AI BI platform with a six-stage natural-language-to-SQL pipeline across four LLM providers, SELECT-only safety enforcement, and SSH bastion tunneling to private databases).

05 / FAQ

Common questions.

What kind of engineering work do you take on?
Production AI/LLM features (RAG, agents, structured outputs across Claude / GPT / Gemini), AWS serverless architecture, and full-stack web builds with Next.js, React, FastAPI, and PostgreSQL. Strongest on multi-tenant SaaS, AI-augmented workflows, and cloud-native systems where reliability matters.
Are you available for full-time roles?
Yes — open to senior software engineer, staff engineer, or tech lead positions, remote-first, ideally with EMEA or US-East timezone overlap. Also open to fractional and contract engagements.
Can I hire you as a freelance AI engineer?
Yes — I take freelance and contract AI engineering work: LLM integration (Claude, GPT, Gemini), RAG pipelines, AI agents, and AWS serverless builds. Engage directly by email, through Contra, or as a fractional senior engineer.
What's a typical engagement length?
Contract work usually runs 4–16 weeks for a focused build (LLM feature integration, MVP, or AWS migration), or ongoing as a fractional senior engineer. Full-time roles are open-ended.
What timezones do you work across?
Based in Lahore, Pakistan (UTC+5 / Asia-Karachi). Standard overlap with EMEA all day and US-East mornings. Comfortable shifting hours for sync-heavy clients.
Which LLM and AI tools have you shipped to production?
Anthropic Claude (Sonnet and Opus), OpenAI GPT-4, Google Gemini, LangChain, embeddings and vector retrieval, AWS Textract for OCR, and custom evals. Recent work: Promptly (a Claude-powered Socratic product architect with a four-gate AI cost guard and 16 metered agent pipelines) and Quanta (natural-language SQL across Gemini, OpenAI, Claude, and Groq with SELECT-only enforcement).
How do I scope a project quickly?
