TechnoDexterous

Backend Engineering

Build the invisible logic that powers applications like Instagram and Spotify.

Core Frameworks

Django (The Battery-Included)
FastAPI (Modern & Fast)

Key Concepts

REST & GraphQL APIs
PostgreSQL & Redis

Senior Tip: "Don't just write the API. Learn how to Dockerize it and deploy it behind an Nginx reverse proxy. That gets you hired."

System Architecture

Request -> API -> DB -> Response

Data Scientist

Build predictive models and uncover hidden patterns in complex data.

Scientific Stack

Pandas & NumPy
SciPy & StatsModels

Modeling

Scikit-Learn
Jupyter Notebooks

Senior Tip: "The model is the easy part. 80% of the work is feature engineering and cleaning the data."

Scientific Process

Clean -> Model -> Validate

AI & Machine Learning

Create intelligent systems that predict, generate, and adapt.

Deep Learning

PyTorch & TensorFlow
Keras

Modern GenAI

LLMs (LangChain)
HuggingFace Transformers

Senior Tip: "You can't build a skyscraper if you can't build a shed. Master Linear Regression before Deep Learning."

Model Training

Data -> Neural Net -> Prediction

Data Engineering

Build the pipelines that move massive amounts of data from A to B reliably.

Pipeline Tools

Apache Airflow (Orchestration)
Spark (PySpark)

Big Data

Kafka (Streaming)
SQL & NoSQL (MongoDB)

Senior Tip: "SQL is your best friend. Python is the glue. Learn how to optimize queries for large datasets."

ETL Pipelines

Extract -> Transform -> Load

Automation Testing (QA)

Write code that breaks code. Ensure quality before every release.

Test Frameworks

Selenium / Playwright
PyTest & Unittest

CI Integration

Jenkins / GitHub Actions
API Testing (Requests)

Senior Tip: "Don't just write scripts. Build a reusable Test Automation Framework that scales with the product."

Test Pyramid

Unit -> Integration -> E2E

Data Analytics

Tell stories with data. Answer the "What happened?" for businesses.

Data Handling

Advanced Excel & VBA
SQL (Complex Queries)

Visualization

PowerBI / Tableau
Python (Matplotlib/Plotly)

Senior Tip: "Your dashboard is useless if it doesn't answer a business question. Focus on the 'So What?', not just the chart."

Business Intelligence

Data -> Dashboard -> Decision

DevOps & Automation

The bridge between code and production. Keep the systems running.

Infrastructure

Docker & Kubernetes
AWS (Boto3) / Azure

Automation

CI/CD Pipelines
Ansible & Terraform

Senior Tip: "This path often pays the highest because it requires you to understand both the Developer's code and the System's needs."

CI/CD Pipeline

Code -> Build -> Test -> Deploy

Role	Focus Area	Entry Barrier
Backend Engineer	Server Logic & APIs	Medium
Data Scientist	Modeling & Prediction	High
Data Engineer	Pipelines & Big Data	High
DevOps Engineer	Cloud & Infrastructure	High
Automation QA	Testing & Quality	Medium
Data Analyst	Reporting & Visuals	Low
