Project details
I am a professional web developer with years of experience behind. I have developed the entire workflow for bug fixing and handling speed optimization jobs: for instance, to deliver them faster, I cloned the project on my hosting to speed up the testing.
I will create a backup and work on the staging instance to not disturb the live site. I will analyze the theme, a stack of modules, server, and database for bug fixing and performance issues, then find how to fix them.
In the end, I will send you a PDF file with before / after tests, a list of all changes, and recommendations on what to change to improve speed further.
My services are not the cheapest, but also are not the most expensive out there and I actually know what I do.

Lahore Cantt, Pakistan - 12:37 pm local time
My core stack is React, Next.js, Node.js, TypeScript, Vue.js, PHP, and Laravel, backed by real-world experience with AWS serverless architecture (Lambda, SQS/SNS, EventBridge, Step Functions) and event-driven system design. I build applications with technical SEO built in from the ground up — clean semantic markup, structured data and schema markup, fast Core Web Vitals, and crawlable architecture — so what I ship doesn't just work well, it's found.
On the AI side, I've built a Retrieval-Augmented Generation (RAG) system from the ground up — using a vector database and local LLMs to power natural-language querying over data — and I'm continuing to grow this into agentic workflows and LangChain-based orchestration. I'm also applying that same thinking to GEO (optimizing content and site structure for AI answer engines such as ChatGPT, Perplexity, and Google AI search results), as it becomes as important as traditional search.
Recent highlights:
- Led development of a delivery-management SaaS product as lead developer — built real-time chat, custom voice calling, a support ticketing system, and a full finance module (loans, advances, salary management, ledgers)
- Built a RAG-based query engine using vector search and local LLMs
- Migrated a web application to a native desktop app using Electron
- Designed and operated event-driven backend services on AWS serverless infrastructure
- Built and optimized web applications for technical SEO — structured data, site speed, Core Web Vitals, crawlability
- Mentored engineering teams through code review and technical standards
Key areas of expertise:
- Full-Stack Development (React, Next.js, Node.js, TypeScript, Laravel, Vue.js)
- Technical SEO & Performance Optimization (Core Web Vitals, structured data, crawlability)
- AWS Serverless & Event-Driven Architecture (Lambda, SQS/SNS, EventBridge, Step Functions)
- RAG Systems, Vector Search & Local LLM Integration
- GEO / AI Search Optimization
- REST APIs & Microservices
- Real-Time Systems (chat, calling, live data)
- Database Design & Optimization
I care about clean architecture, performance, and discoverability — not just shipping fast, but shipping things that get found and used. If you need a reliable engineer who can own a feature or a whole product end to end, let's talk about your project.
Steps for completing your project
After purchasing the project, send requirements so Yisal can start the project.
Delivery time starts when Yisal receives requirements from you.
Yisal works on your project following the steps below.
Revisions may occur after the delivery date.
Analysis
After you send a request, I analyze your website and come back with suggestions. I never send generic responses, so that it might take time.
Preparation
Backup is the very first step I take. The safety of your data is a must. At this stage, I also run speed tests to compare them with later results, and I also test the website to reproduce the issue.
