Open to senior roles, architecture consulting and fractional CTO workOpen to senior roles & consulting
Eight years ago I was fixing PHP in a school management system in Lahore. Today I lead ten engineers on a real estate platform that 20,000 agents use every day, and I build the AI agents that handle its support.
I still write code most days. I also write the architecture down before anyone does, because the expensive mistakes are the decisions nobody recorded.
8+ years, junior to architect · 20k+ agents on platforms I lead · 80k+ patients served by APIs I built · ~90% support tickets handled by AI agents.
Leading the REConnect team at SL Tech, shipping the MCP support agent to more brokerages, and taking one architecture audit a month on the side.

Decision log
Architecture decision records from real projects: the situation, the call, what it did. The latest three; the full log has the rest and an RSS feed.
Context Letting Claude deploy through MCP needed per-user identity, consent and rate limits. Coolify only offers static tokens.
Decision A small Node service implementing OAuth 2.0 for MCP clients, sessions in Supabase, scoped tools and an audit log. Tokens never leave the server.
Result Prompt-driven deployments with a consent trail security could sign off on, supporting 25+ deploys a week.
Context Model bills grow silently. The team needed a number the business understood and a lever to pull.
Decision Frozen system prompts for cache hits, model routing by task difficulty, evals before any model switch, and a dashboard of cost per resolved conversation.
Result Quality tracked on an eval set and spend tied to a business outcome, so model changes became routine instead of risky.
Context The support agent needed live account and listing data, and the risk of a model issuing broad queries or actions was unacceptable.
Decision Every capability is a tool with a schema, an allow-list of roles, and consent for anything destructive. Retrieval is grounded; the model cannot reach the database directly.
Result About 90% of tickets resolved end to end with an auditable trail and no incident from an agent action.

How I work
Whether it's a Laravel API, a Next.js frontend or a support agent on the Claude API.
A short discovery on what the system has to do, who uses it, what breaks today and what “done” looks like in numbers. No proposals written from the brief alone.
Data model, tenant isolation, service boundaries and the tool surface any AI agent is allowed to touch. Written down, reviewed with you, before code.
Production-shaped increments from week one: real deploy pipeline, real data, real users as early as it is safe. Tests on the paths that lose money when they break.
Monitoring, runbooks and, for AI features, an eval set and cost per resolved task. Then hand over cleanly or stay on as the lead.
Writing
How to pull MLS listings through the RESO Web API into a Laravel platform without drowning in dialects: OData queries, incremental sync, media, rate limits and the one normalization decision that keeps you sane.
What an MCP server needs before security will let an AI assistant touch real systems: discovery metadata, PKCE, dynamic client registration, scopes, consent, token lifetimes, idempotency and audit.
Prompt caching can cut LLM input cost by more than half, but only if the prefix is byte-identical. The silent invalidators I keep finding in production code, and how to structure requests so caching actually hits.
The difference between a chatbot demo and a support agent that closes real tickets: retrieval design, typed tools, role-aware behaviour, evals and the metric we actually optimised.
FAQ
Short answers. For anything else, use the assistant in the corner or email me.
Yes. I have 8+ years of experience and I am open to senior remote software engineering roles, especially full-stack, backend-heavy and AI-integration positions with US or UK teams.
Yes. Typical shapes are a two-week architecture audit with a written target design, a fractional engagement of a few hours a week guiding a team, or technical due diligence before an investment or acquisition.
Yes. I take contract work for full-stack platforms, Laravel and React builds, API architecture, and production AI systems such as RAG chatbots, MCP servers and tool-calling agents.
PHP/Laravel, JavaScript/TypeScript, Node.js/NestJS and React/Next.js, plus Vue and Nuxt. Databases and cloud: MySQL, PostgreSQL, MongoDB, Redis, AWS, Docker, Terraform and GitHub Actions. AI: the Claude and OpenAI APIs, RAG, MCP servers and clients, agents and tool calling.
Start from the workflow, not the model. I ground answers in your data with retrieval, give the model typed tools instead of free-form actions, add guardrails and evals before launch, and track cost per resolved task. The REConnect support agent went from prototype to handling about 90% of tickets this way.
