Project details
I will build and deploy a complete full-stack web application, including the frontend, backend, database, APIs, authentication, integrations, and production environment.
I work with React, Next.js, TypeScript, Python, FastAPI, Django, Node.js, PostgreSQL, Docker, and AWS. The service is suitable for SaaS products, dashboards, marketplaces, internal platforms, automation systems, and AI-assisted tools.
Before development, I review the requirements and define the scope, architecture, user flows, database model, integrations, deployment plan, and technical risks.
You receive a responsive application, maintainable source code, deployment setup, and documentation. More complex platforms may require a custom quote after a technical review.

Lexoffice API Integration & Monthly Accounting CSV Export
Aldo was resolving a challenge related to a recurring CSV-Export from Lexoffice to support us on reporting and accounting. He therefore drafted a very efficient and relyable script for a total of three individual CSV files and the respective schedulers. We really enjoyed the quick and direct back-and-forth sparring on additional requests from our end as well as on resolving experienced challenges e.g. due to local formatting etc.
We can absolutely recommend working with him as he experienced him not only as fully committed but also capable of delivering on-spot quality work while at the same time being a great communicatior who is open for feedback and additional requests. Everything we asked for was implemented in a quick and reliable manner. 5 Stars from our side!

Job Success
Atyrau, Kazakhstan - 2:46 am local time
Expert in: Python, Go, Typescript, Cloud, AI Agents
I help companies build new software, automate expensive manual work, fix slow or fragile systems, and turn complex ideas into reliable products.
From full-stack SaaS and AI automation to data platforms, APIs, MCP, LLM integrations, RAG, web scraping, ETL, analytics, and cloud infrastructure, I can take ownership from the first technical decision through production and long-term improvement.
If your product needs to be built, rescued, automated, scaled, or pushed across the finish line, I can own the technical side end to end.
━━━━━━━━━━━━━━━━━━━━━━━━━━━━
WHAT I HELP COMPANIES DO
01 BUILD PRODUCTS
Full-stack SaaS platforms, internal tools, dashboards,
APIs, backend systems, and customer-facing applications.
02 AUTOMATE WORK
AI agents, RAG, LLM workflows, MCP integrations,
data collection, research, operations, and repetitive processes.
03 FIX COMPLEX SYSTEMS
Slow applications, fragile architectures, database bottlenecks,
unreliable pipelines, integrations, and legacy codebases.
04 SCALE DATA & INFRASTRUCTURE
ETL pipelines, scraping systems, background workers,
PostgreSQL, Redis, Elasticsearch, AWS, Docker, and CI/CD.
━━━━━━━━━━━━━━━━━━━━━━━━━━━━
SELECTED RESULTS
900M+
records handled across production systems
400+
websites automated for large-scale data collection
5M+
structured records produced from automated pipelines
3.5M
live events processed through a real-time PostgreSQL + Redis system
6×
faster analytics performance across 3,000+ dynamic columns
━━━━━━━━━━━━━━━━━━━━━━━━━━━━
TYPICAL PROBLEMS I AM BROUGHT IN TO SOLVE
“We need to build this.”
→ I can take it from architecture to production.
“Our application works, but it is slow or unreliable.”
→ I identify the real bottleneck and fix the underlying problem.
“We are doing too much manually.”
→ I turn the workflow into software or AI automation.
“We have a lot of data, but cannot use it properly.”
→ I build the collection, processing, storage, API, analytics, and UI around it.
“The project is technically complicated and nobody owns the whole thing.”
→ I can own the complete technical path.

Improvement
I am comfortable joining an existing codebase or starting from a blank repository.
I can handle architecture, implementation, integrations, debugging, performance work, deployment, infrastructure, and ongoing technical improvement without requiring the project to be split across multiple specialists.

SEND ME THE PROBLEM
You can send me three things:
01 What you are trying to build or fix
02 Your current stack, if one exists
03 The main technical or business bottleneck
I will tell you how I would approach it, where the biggest risks are, and the shortest practical path to production.
Steps for completing your project
After purchasing the project, send requirements so Aldo can start the project.
Delivery time starts when Aldo receives requirements from you.
Aldo works on your project following the steps below.
Revisions may occur after the delivery date.
Discussion of application philosophy, design & purpose
I will break down into items based on your requirements, prioritorize and agree final steps for build
