Logistika.io – High-Performance Logistics & Fleet Management System
🛑 The Challenge
Traditional logistics companies often struggle with fragmented operations. The client was managing shipments, invoicing, and fleet tracking across different outdated spreadsheets and manual Telegram groups. This led to:
Slow data processing: Generating custom monthly financial reports took hours.
High database latency: Tracking thousands of simultaneous shipments caused lag spikes on their basic server setup.
Missed payments: Managing pending invoices manually led to late payment notices and lost revenue.
💡 The Solution
I built Logistika.io, a unified, multi-tenant administrative dashboard that centralizes operational overviews, real-time shipment monitoring, role-based staff management, and automated invoicing.
To solve the performance bottlenecks, I implemented the following technical optimizations:
Speed Optimization via Redis: I integrated Redis caching for frequently read operational metrics (like active transit count and monthly revenue). This reduced database query response times by 75% (from 250ms down to ~60ms).
Asynchronous Document Generation: Instead of generating Excel/PDF export files directly inside the request-response cycle, I offloaded these heavy tasks to a background worker queue using Celery & RabbitMQ.
Unified Multi-Gateway Billing: Integrated dynamic payment statuses using webhooks for popular local and global gateways (Click, Payme, and Stripe).
🛠️ Tech Stack & Architecture
Frontend: React, Tailwind CSS (for a fully responsive, pixel-perfect administrative UI)
Backend: Python (FastAPI/Django), RESTful API, Celery (for background tasks)
Database & Cache: PostgreSQL (for relational data integrity), Redis (for query caching)
DevOps: Docker, Nginx, PostgreSQL Replication

Currently designing and building a custom web app for a friend that works as an alternative to platforms like PhotoShelter and SmugMug.
It’s becoming easier for people to replace expensive monthly tools with products built specifically around their own workflow, features, and business needs.
Need something custom built for the way you work? Let’s talk.
A photographer-specific alternative to PhotoShelter makes a lot of sense, those platforms feel bloated if you only need galleries and client proofing. Are you building the storage/CDN piece yourself or wiring up something like S3 behind it?
Day 5/30: MISREGISTER
An operating-room case can still look ready on paper after it has stopped being operationally executable.
I built MISREGISTER to make that gap physical.
CASE 04 is connected to four changing dependencies:
— staffed OR team
— sterile instrument set
— postoperative ICU bed
— remaining operating-room time
As those windows drift apart, the operating list stays unchanged.
The signature moment: the crank freewheels to the end-stop while CASE 04 still reads SCHEDULED.
Only after that failed test does a human re-strike the case as DELAYED or RESEQUENCED.
This is not clinical decision support. It is a synthetic operational prototype exploring the difference between a scheduled slot and executable capacity.
Built with React, TypeScript, SVG, Playwright, Remotion, Claude Code, Kimi, Agent Reach, ChatGPT, and AI33Pro.
Live prototype:

Making readiness physically understandable instead of dashboard-inferred is such a good design goal, that's usually the exact gap that causes people to ignore dashboards in the first place. Curious to see where you take the physical interaction idea next.
A realtor or a business in need of python and LLM AI document processing? Here are some recaps of my previous internship I did.
Just completed some advanced level python and LLM from extern for a mortgage company.
Check out some of the project I've worked on
Engineered AI-powered document processing pipelines for 200+ page mortgage files using OCR technologies including Tesseract OCR, PaddleOCR, and PyMuPDF, enabling scalable document extraction and parsing.
Developed a Retrieval-Augmented Generation (RAG) system using LlamaIndex for intelligent document search, classification, and contextual retrieval workflows.
Improved retrieval accuracy and system performance through embedding optimization, chunking strategies, vector search tuning, and intelligent routing logic.
Delivered technical documentation, demo UI, and evaluation reports validating OCR accuracy, retrieval precision, and system readiness for production deployment.

The OCR plus RAG pipeline for 200-page mortgage files sounds like a serious test of retrieval quality. Which document type caused the toughest extraction or chunking issue?
