About Dinh

Dinh N.Status: Offline
Python Backend Engineer | AI Integration, APIs, Workflow Automation
Ho Chi Minh City, Vietnam - 12:04 pm local time
In early 2023, right after ChatGPT launched, a tech founder hired me with an idea and no product. He wanted his own personalized AI chat platform, with image generation built in from day one.

3.5 months later, it was live. Django backend, React UI, OpenAI API, third-party image generation.

Some of the best features weren't in his spec. I proposed preset chatbot roles so users could switch personas in one click instead of typing prompts from scratch. He loved it. I also walked him through everything outside the code: which VPS to pick, how to manage API keys, UX trade-offs.

His review is still on my profile: "Tremendously talented, respectful and responsible!! The developer we would all want in our teams."

Since then I've spent three years building backend systems for banks, where a silent failure costs real money. Recent results:
- Optimized an automated debt collection system for a major bank: throughput 209 → 802 accounts/min (+282%), processing time down 74%
- Cut interbank transaction failure rate from 30% to 2.5%. Processing time went from 120 seconds to about 1.5
- Led a team of 8 engineers as Technical Lead/Founder: architecture, code standards, CI/CD (Jenkins, Docker, Kubernetes), payment gateway integrations
- Deployed a generative AI model for real-time image processing in a production consumer app

Now I'm back on Upwork, doing one thing: AI integration and automation built like production software. Not demos that break the week after delivery.

WHAT I BUILD

AI Integration
LLM features inside your product: OpenAI and Claude APIs, function calling, custom chat interfaces, document processing. I've been shipping with GPT APIs since they launched.

Backend Automation & APIs
Python (Django, FastAPI) systems that connect your tools. REST APIs, webhooks, scheduled jobs, payment gateways, messaging (Telegram, WhatsApp, Zalo).

Workflow Automation
n8n when no-code fits. Custom code when it doesn't. Either way you get documentation, so your team can maintain it without me.

Web Scraping & Data Pipelines
Selenium and API-based collection, cleaning, storage. A past client put it simply: "One of the best freelancers I worked with. I will hire him again."

WHO HIRES ME

Founders and teams tired of:
- AI features that demo well and fall apart in production
- Automations that fail silently until a customer complains
- Freelancers who build exactly what's in the ticket, nothing more
- Undocumented systems nobody can maintain


HOW I WORK

Written-first. You get a clear plan before I write code, then structured progress updates through chat and email. No chasing me for status.

Every system ships with docs your team can actually use.

Any timezone works. My clients have been in the US, Europe, and Asia.

TECH STACK

Languages: Python (primary), Go, JavaScript/TypeScript
Backend: Django, FastAPI, Flask, Celery
AI/LLM: OpenAI API, Claude API, function calling, prompt engineering, n8n
Data: PostgreSQL, MySQL, MongoDB, Redis, Kafka
Infra: Docker, Kubernetes, Jenkins, Nginx, AWS, GCP, DigitalOcean
Scraping: Selenium, REST API automation

Send me a short description of what you're trying to automate or build. I'll reply with a concrete plan: what I'd build, how long it takes, what it costs.
