You will get production-Ready Backend (python, ruby, Go) REST API with Database


Project details
Most freelancers send you code and hope it works. I send you an architecture doc first, build clean typed Python with full pytest coverage, and hand off a Dockerized, documented API that's ready to deploy. 3+ years shipping production backends for high-traffic e-commerce and 10+ banking systems — performance, security, and reliability are the default, not an upgrade.

About Aliz
Backend Engineer| Python,FastAPI,AWS,Microservices,Distributed System
Kathmandu, Nepal - 9:17 am local time
What I deliver?
→ Backend APIs & microservices (Python, FastAPI, Flask, Django, REST, WebSockets)
→ AWS cloud architecture (Lambda, API Gateway, EC2, S3, CloudFormation, ELB)
→ Payment gateway integrations (card tokenization, dynamic QR, multi-provider routing)
→ Performance optimization (query tuning, Redis caching, profiling, 25–40% gains)
→ Real-time data pipelines (RabbitMQ, event-driven architecture, WebSockets)
→ Database design & optimization (PostgreSQL, MySQL, MongoDB, Redis, OpenSearch)
→ ERP integrations & custom Odoo modules
→ CI/CD pipelines, Dockerized deployments, Linux ops
My shipped outcomes?
- Architected a real-time order processing platform with vendor collaboration via RabbitMQ — improved product availability by 40% and order accuracy by 60% for a high-traffic e-commerce platform.
- Integrated multiple payment gateways (card tokenization + dynamic QR) on AWS Lambda — expanded payment coverage by 100% while meeting enterprise-grade security standards.
- Cut homepage load time by 30% and server response by 25% through API separation, query tuning, and a Redis migration.
- Deployed backend infrastructure across 10+ banks in live production environments, debugging real-time microservice issues with chartered accountants, compliance officers, and bank IT teams.
- Built a Flask engine with a unified data access layer processing 1M+ rows of transaction data.
- Odoo ERP migration (v13 → v16), achieving 30% faster internal processing.
How I work with clients:
I work best with founders, CTOs, and product teams who need a senior backend partner who can take a problem from ambiguous brief to shipped code without hand-holding. I write architecture docs before I write code, communicate proactively in async (Slack/Loom/Notion), and treat your codebase like equity: clean, tested, and built to outlast me.
I'm based in Nepal (UTC+5:45), which gives me strong overlap with:
- Australia & APAC (full workday overlap)
- Europe / UK (4–6 hour overlap window)
- US East Coast (early morning your time / evening mine, async-friendly)
I currently work with clients in the US, EU, and Australia on both fixed-scope projects and ongoing fractional retainers.
Best engagements for me:
- Building or scaling a backend MVP from 0 → 1
- Payment integration, fintech APIs, or compliance-sensitive systems
- Performance audits and bottleneck removal
- AWS architecture review or migration
- Fractional backend lead for early-stage startups (10–25 hrs/week)
- Rescuing or refactoring legacy Python codebases
Tech I use daily:
Python · FastAPI · Flask · Django · SQLAlchemy · PostgreSQL · MySQL · MongoDB · Redis · AWS (Lambda, API Gateway, EC2, S3, CloudFormation) · Docker · RabbitMQ · WebSockets · OpenSearch · Nginx · Linux · Git · pytest
Credentials:
- Licensed Computer Engineer — Nepal Engineering Council
- B.E. Computer Engineering — Purbanchal University
- IBM Certified — Generative AI & LLMs: Architecture and Data Preparation
If you're building something that needs a backend that won't fall over at scale, send me a message with your stack and the problem you're trying to solve. I reply within a few hours and offer a free 20-minute discovery call to scope fit before either of us commits.
Steps for completing your project
After purchasing the project, send requirements so Aliz can start the project.
Delivery time starts when Aliz receives requirements from you.
Aliz works on your project following the steps below.
Revisions may occur after the delivery date.
Discovery & Requirements Review
I review your requirements and any shared files, then send a short questionnaire or hop on a 15-min call to confirm endpoints, data model, and auth. So we're fully aligned before any code is written.
Architecture & API Design
I design the database schema and API spec (endpoints, request/response models) and send it for your approval. You sign off before I build. No surprises, no wasted work.
