Hi, I'm Kian! It's nice to meet you! I hate boring, repetitive work, and I'm sure you do too! Having to do the same thing over and over again is emotionally draining and hard. I'm a freelance developer and automation specialist with a passion for simplifying workflows and tasks, especially ones that integrate with Google Workspace or Google Cloud. Apps Script provides a quick, flexible, and powerful way to create automation that works with Google's services, as well as integrating with other platforms. I'm most proud of my ability to get up to speed very quickly. For a previous company, I learned their programming language of choice on-the-job, and was mentoring my coworkers within the first few weeks! Quick bit of humor: I loved taking apart electronics as a kid. I'd try to build robots, combine computers together to create more powerful ones, etc. I'd like to attribute my skills to an earlier experience, however. When I was 3 years old, I threw my parents' camera down the stairs. That moment started it all! :) Thanks for reading! Kian.

Throughout my career, I've had the privilege of working closely with a diverse range of clients, predominantly in the United States, since 2012. My natural ability to connect with people and understand their unique needs has been instrumental in executing and achieving complex project goals. I consider myself a friendly individual who enjoys the social aspect of my role as much as the technical, an attribute that has significantly contributed to my success in the field. Notably, I have played a pivotal role in the development and subsequent success of various software products, with a couple of them being acquired by prestigious companies like Dropbox. This achievement, I believe, attests to my commitment to excellence, innovation, and the capacity to drive projects from inception to completion. My creativity is another factor that sets me apart in the industry. Over the years, I've found myself drawn towards visual elements in software development, leading me to specialize in frontend projects. This creative streak has allowed me to innovate and develop visually stunning and user-friendly software solutions that meet and often exceed client expectations

I build ERP, SaaS, and CRM systems that businesses actually run their operations on — not demos, not prototypes. 12+ years, 2,600+ hours on Upwork, Top Rated. Most "full stack developers" write CRUD screens and call it done. I design the data model, the workflow state machine, and the access control underneath a system before I write a line of UI — because that's what decides whether your ERP still works cleanly two years and forty feature requests later, or needs a rewrite. Increasingly, that means wiring AI directly into the systems I build — not as a chatbot bolted on the side, but as a structured layer that reasons over your actual data: smart search across your records, AI-assisted reporting, automated document/email processing, and agent-style workflows that act on your CRM or ERP data instead of just answering questions about it. What I've shipped: - Enterprise ERP modules covering HR, finance, and operations workflows - CRM and campaign systems redesigned around proper lifecycle states — pending, approved, queued — instead of fragile ad-hoc logic that breaks under edge cases - AI/LLM integration into existing backends — structured data extraction, RAG-based search over business records, automated workflows triggered by AI-evaluated conditions - Healthcare MIS systems handling patient and clinic workflows - S3-integrated document/media systems with pre-signed URL handling for secure, scalable file delivery - LMS platforms with student portals, course management, and role-based access - Mobile apps shipped to Android & iOS (React Native, Flutter) Core stack: Laravel (PHP), MERN (MongoDB, Express, React, Node), Vue.js, MySQL, REST APIs, AWS (S3 and related services), OpenAI/Claude API integration, React Native, Flutter. How I work: - I plan the schema and API contract before development starts, not during it - I track time and share milestone updates proactively — non-negotiable on every engagement now - I write code meant to be maintained by someone else later, not just shipped to pass review - I flag problems before you've paid for them, not after If you need someone who treats your ERP, CRM, or SaaS product like infrastructure with long-term consequences — and wants AI to actually do something useful inside it, not just sit on top as a demo feature — let's talk about what you're building.

Looking for an experienced software engineer who has extensive industry experience, wide ranging technical skills, great communication skills, can work independently, and has an ability to really 'get' the big vision of what you want to achieve? Need someone who can fine-tune your new AI app or figure out why it's not working? UNDERSTANDING I don't just blindly focus on the technical aspects of the project. I will make sure that I understand exactly what your business wants and how the project will be used in the real world, so I can deliver something that is intuitive for users and exceeds your expectations. CREATIVITY I love coming up with brilliant and creative ideas for how your product could be improved or tweaked. If you're looking for a passive, mindless worker then you should hire someone else. I will frequently inject fresh new ideas into the discussion, and challenge your thinking. QUALITY What I can offer that you probably won't find from other freelancers here is a very high level of production build quality and testing. Instead of delivering the minimum to you, I excel in delivering a high-quality product that is not an unstable or incomplete prototype, but a production-ready product that is complete, user-friendly, intuitive, and free of bugs. EXPERIENCE I have 15+ years of experience as a software developer, building both front-end and back-end software applications, specialising in Java, JavaScript, React, Python, Django, C#, and SQL. I can integrate with LLMs such as ChatGPT to build AI features. I'm confident solving complex problems, designing new architectures, building DevOps pipelines, integrating 3rd party APIs, designing relational databases. I have exceptional skills in the area of problem-solving and trouble-shooting. COMMUNICATION What also sets me apart from most developers are my fantastic communication and people skills, making me a breeze to work with, and allowing you to understand the big picture even if you’re not a technical person. INDEPENDENCE I have and an ability to work independently to make technical decisions and solve problems, meaning you don't have to waste time micro-managing me. But it's up to you how much you delegate. I will find out from you which decisions you want to be a part of, and which ones you are happy to entrust to me. You always have the final say. WHAT TO EXPECT If I start a project with you, here is what to expect: 1. I will have a lengthy conversation with you to make sure I fully understand all of your expectations and requirements. Based on this, we will agree on individual delivery milestones. 3. I will write up the technical design for each milestone, along with an estimate of development time, and a plan for how to quality test it once it's complete. 4. I will work on each milestone and deliver a preview of it to you for feedback and minor tweaks. 5. I will then begin a round of quality testing to find bugs and ensure the product is stable and complete. 6. We will discuss and feedback and also bugs found during testing, and negotiate what can be realistically changed or fixed within the timeframe and budget of the project. 7. I will apply any fixes or minor tweaks that we agreed upon. 8. I will then deliver the final version of the software to you, complete with documentation for how to set up the development environment, how to deploy the software, and how to use it. Don’t wait, get in touch now and we can plan our first project together!

I’ve built secure third-party integrations, designed systems meant to scale under real production load, and worked directly with founders and stakeholders. I understand business constraints, technical debt, and delivery pressure because I’ve owned real products. HOW I WORK Clean, maintainable, production-ready code Clear communication and ownership mindset Architecture decisions explained in simple terms Long-term solutions instead of short-term hacks Whether you’re building a new SaaS product, scaling an existing system, adding AI automation, or fixing architecture and performance issues, I bring clarity, structure, and execution. Let’s build something that actually works — and scales.

Expert-Vetted AI & Full-Stack Engineer | 100% Job Success | 30+ Projects | $170K+ Earned Past Experience : Goldman Sachs, Morgan Stanley, KPMG, Oracle & Others I help startups and enterprises ship AI products and the backend systems behind them — from RAG chatbots and LLM integrations to scalable APIs, data pipelines, and production deployments. 10+ years building software. 30+ Upwork projects, all 5-star rated. Expert-Vetted (top 1%). One engineer who can own the problem from architecture to live product — clear communication, on-time delivery, code that scales. WHAT I BUILD AI & LLM • RAG chatbots and knowledge assistants over PDFs, docs, wikis, Notion, and internal APIs • LLM integration with OpenAI (GPT-4o, GPT-4), Anthropic Claude, and Google Gemini • AI agents with tool use — CRM, email, Slack, webhooks — plus guardrails and human approval • Streaming chat UIs with conversation memory, citations, and admin dashboards • LangChain, LlamaIndex, vector search (Pinecone, pgvector, Chroma, Weaviate, Qdrant) Backend & APIs • REST and GraphQL APIs in Python (FastAPI, Django, Flask), Node.js, and Java/Spring Boot • Microservices, event-driven architecture, authentication, and third-party integrations • PostgreSQL, Redis, MongoDB — schema design, optimization, migrations • Data pipelines with Kafka, Spark, and Airflow for analytics and ETL Frontend & Cloud • React, TypeScript, Next.js, Angular — SaaS dashboards and polished product UIs • AWS, GCP, Azure — Docker, CI/CD, monitoring, production hardening WHY CLIENTS HIRE ME Most AI projects break at the seams — weak APIs, messy data ingestion, no real UI, nothing deployed. I deliver the full path: data in → embeddings & retrieval → LLM → API → frontend → cloud.
