Cover image for Designed & Custom-built something fresh
Designed & Custom-built something fresh for OneOqood - a B2B real estate enterprise. The founder wanted an attractive first look that immediately grabs the attention of brands and organizations looking to scale their physical locations. A multi-layered search bar with tight copy clearly conveys OneOqood’s message right from the entry point. The footer links are clean, paired with a prominent big CTA. Would love some comments! Like for the final site URL and more design screenshots.

Cover image for US property owners managing renovations
US property owners managing renovations juggle scopes, service orders, and contractors across calls and spreadsheets. Renovate360 puts that workflow in one place, on web and mobile. I designed and built the AWS serverless backend: Lambda for compute, DynamoDB for data, CloudFormation for infrastructure as code. No servers to manage, costs that scale with usage. The platform covers property registration, project scoping, service order management, and real-time tracking across owners, managers, and providers, with a web app and React Native mobile app for on-site teams.

Cover image for Alma Collective, a fitness booking
Alma Collective, a fitness booking platform for the Greek market, was stuck: half-built by a previous developer, unstable, and nowhere near launch-ready. I took over the codebase, stabilized it, completed the missing core flows, and carried it to public launch across web and mobile (React Native). What shipped: User app: discover and filter classes (yoga, Pilates, dance), book and pay per session, QR check-in on arrival Partner portal: venue listings, class scheduling, payouts, subscriptions Payments: Stripe with Apple Pay and Google Pay, pay-as-you-go and subscriptions

Cover image for BioSonic is an AI-driven platform
BioSonic is an AI-driven platform for analyzing bat acoustics used by research teams across Europe. I built the full web portal from scratch and transformed it into a high-performance, scalable system capable of handling multi-terabyte datasets. My role covered full-stack development, infrastructure optimization, and performance engineering. I optimized Supabase RPCs and SQL queries, achieving 5× faster data retrieval and 240% faster file loading, while stabilizing AWS services to eliminate downtime. I also enhanced the SQS-based job distribution system for parallel data processing and implemented EC2 monitoring tools for better reliability and proactive scaling. This project showcases my ability to own complex systems end-to-end, improve large-scale performance, and deliver production-ready solutions under tight deadlines, all while maintaining clear communication and client satisfaction. “Hammad created our web portal from nothing in 3 months, optimized it beyond expectations, and always went the extra mile.” — Josef Carlson

if you didn’t know LangChain (https://www.langchain.com/) V1 launched last month, you’re officially late to the party, at least I was until I stumbled into it while upgrading a client’s system. What I discovered completely changed the project. I had developed RAG agent with LangChain v0.3 The plan? Add document generation and agent behavior on top. Then I dug into V1. The result? Enabled intent-based tool use, real tools, short/long-term memory, stable multi-step reasoning, runtime model switching, and predictable actions. What started as a "simple upgrade" turned into building something that actually felt intelligent. The lesson? When a framework makes a leap this big, resistance is more expensive than rewriting. I'll be sharing how I built the document generation tools and the lessons that saved me hours of debugging.

My AI agent was working… but I had no idea why it worked sometimes and completely fell apart other times. That’s when I plugged in LangSmith , and realized I’d been flying blind. Suddenly, my “agentic AI” wasn’t a black box anymore, I could see everything: Every tool call, LLM invocation and retry the agent made, also token burned & cached, state transition across agent steps What surprised me most wasn’t the bugs , it was the waste. One trace showed my system prompt alone was 6.5k tokens. Not because it needed to be… but because I never saw it before. So I fixed it. Refactored prompts -> 1.5k tokens, same output quality Switched to dynamic system prompts, injected only when complexity demanded it Lesson learned: If you’re building agentic systems without observability
