Business Development Representative

I build outbound systems that turn cold leads into warm conversations—and scalable pipeline.

With a background in Enterprise SaaS and experience across EMEA/DACH markets, I specialize in account-based sales development that blends strategic cold calling, cold email, video prospecting and advanced sales automation. I’ve generated over €3M in pipeline by designing outbound workflows that consistently deliver 20%+ phone connect rates and high-quality SQLs.

My tech stack includes tools like Clay, Apollo, Smartlead, Outreach.io, and LinkedIn Sales Navigator—but it’s not just about tools. I also tap into curated, human-verified data sources to fuel Phone-First campaigns with contacts that match exact ICP criteria, ensuring higher precision and high dial:connect ratios.

I’ve worked remotely with high-growth companies and lean go-to-market teams, consistently exceeding quota and contributing directly to closed-won revenue. My experience spans the full sales funnel—from prequalification and TAM mapping to pipeline management and sales enablement.

I believe great sales isn’t about volume—it’s about velocity and relevance. If you’re scaling a team, entering a new market, or want to talk shop about sales automation, let’s connect.

Python for Data Professionals: Why It’s the Preferred Choice

📍 Why is Python the go-to language for data roles?

Python isn’t just a programming language—it’s an essential tool for data professionals. Its simplicity, versatility, and vast ecosystem of libraries make it a top choice for handling complex data challenges with ease.

📍 Where does Python fit in the data ecosystem?

🔴 Data ingestion, cleaning, and transformation
🔴 Storage and orchestration
🔴 Visualization and reporting
🔴 Machine learning and model deployment

From building ETL pipelines to creating interactive dashboards, Python empowers data teams at every level.

📍 Why choose Python over Scala/Java?

While Scala and Java are excellent for large-scale data processing and system robustness, Python stands out for its flexibility. It’s a universal tool, adaptable across various data domains, making it the preferred choice for many professionals.
📍 Key data roles where Python is invaluable:
🔴 Data Analytics – Analyze data using Pandas, NumPy
🔴 Data Visualization – Create stunning visuals with Seaborn, Matplotlib, Plotly
🔴 Machine Learning – Build models with Scikit-learn, TensorFlow, Keras
🔴 Web Scraping – Extract data using Scrapy, BeautifulSoup, Selenium
🔴 Data Engineering – Implement pipelines with Spark, Kafka, Flink
🔴 Databases – Work with SQLite, PostgreSQL, MongoDB, MySQL

📍 Top free platforms to upskill in Python:
 - realpython.com
- pythonprogramming.net
- datacamp.com (free basic courses)
- w3schools.com/python

Ever wondered how companies actually build AI systems powered by LLMs?

It’s not just about calling an API and hoping for magic.

There’s an entire tech stack behind the scenes — and once you understand it, you’ll see how everything connects.

Let’s break it down step by step 👇

🟡 Step 1: The Brain (LLMs)
 Think of GPT, Gemini, or Claude as the intelligence layer.
 They understand, reason, and respond — but they need context, data, and direction.

🟡 Step 2: The Connectors (Frameworks)
 Frameworks like LangChain or LlamaIndex act as plumbing between your model and your tools.
 They let you combine the LLM with data sources, APIs, and logic — no need to reinvent the wheel.

🟡 Step 3: The Memory (Vector Databases)
 LLMs forget fast.
 That’s where databases like Pinecone, Weaviate, and Chroma come in — they store “embeddings” (a fancy word for text turned into numbers).
 It’s like giving your AI Google Search for your own data.

🟡 Step 4: The Fuel (Data Extraction)
 No data, no intelligence.
 Tools like Crawl4AI and FireCrawl pull information from PDFs, websites, and documents — then clean it so your AI can actually use it.

🟡 Step 5: The Open Source Edge
 Don’t want to rely on expensive APIs?
 Use open models from Hugging Face or run local ones via Ollama.
 Freedom + privacy + control = ✅

🟡 Step 6: The Language of Numbers (Embeddings)
 Before your text hits the vector DB, it must be converted into numerical form.
 That’s where OpenAI Embeddings or SBERT come in — enabling true semantic understanding.

🟡 Step 7: The Quality Gate (Evaluation)
Now test it.
Use tools like Giskard or Trulens to check for accuracy, hallucinations, and relevance.
Because every smart system needs smarter feedback loops.

💥 In short:
 1️⃣ Pick your LLM
 2️⃣ Connect it via a framework
 3️⃣ Feed it structured data
 4️⃣ Store it in a vector DB
 5️⃣ Add embeddings for meaning
 6️⃣ Use open tools for flexibility
 7️⃣ Evaluate relentlessly

This blueprint can help your team go from idea to intelligent system.

Ever wondered how Agentic AI actually works behind the scenes?

Here’s a simple breakdown of how an AI agent transforms raw input → into intelligent output.

 Perfect for anyone curious about how autonomous AI systems really think. 

🟠 Input Sources
 Agentic AI starts by collecting data from multiple channels — knowledge bases, user queries, APIs, logs, and web data.

🟠  AI Processing
Once data is gathered, the agent gets to work — analyzing the query, reasoning through context, retrieving memory, planning tasks, selecting tools, and managing the entire flow.

🟠 3. Action Layer
 With a clear understanding of context, the agent performs real-world actions — making decisions, executing tasks, fixing errors, collaborating with other agents, and even scheduling future steps.

🟠 4. Output
 Finally, it delivers a response that’s accurate, relevant, and context-aware — the hallmark of truly autonomous intelligence.
That’s what sets Agentic AI apart from traditional chatbots or rule-based systems.

freeCodeCamp  recently released a comprehensive AI Engineering Roadmap — and it’s surprising how many people missed it.

It’s not just another tutorial list.
It’s a reality check for anyone serious about building a career in AI.

Here are some key takeaways worth reflecting on 👇


🔴 1. Math is non-negotiable
Linear algebra, calculus, and probability form the backbone of every AI system.
If you can’t understand gradients, optimization, and loss functions — you’ll struggle to build anything meaningful.

🔴 2. Python remains the foundation
From TensorFlow and PyTorch to NumPy and Pandas — this ecosystem drives modern AI.
Fluency in Python isn’t optional; it’s expected.

🔴 3. LLMs aren’t everything
While everyone is chasing ChatGPT replicas, real impact (and opportunity) lies in building domain-specific models that solve practical business problems.

🔴 4. Depth beats credentials
Building and deploying CNNs, RNNs, and LSTMs will teach you far more than any certificate ever could.

🔴 5. Data work is underrated
Data cleaning, transformation, and validation consume most of an AI engineer’s time — and mastering these makes you truly valuable.

🔴 6. Prompt engineering isn’t the destination
It’s a useful skill — but true AI engineers design systems, not just prompts.

🔴 7. Deployment is the differentiator
A model sitting in a Jupyter notebook has no value.
Productionization is where engineering begins.

🔴 8. Generative AI goes beyond LLMs
Understanding GANs, VAEs, and foundational architectures separates professionals from hobbyists.

🔴 9. System design matters
AI solutions must scale. Knowing Kubernetes, Docker, and distributed systems is critical for real-world impact.

🔴 10. Ethics and bias awareness are essential
As AI adoption accelerates, responsible design and fairness aren’t optional — they’re requirements for trust and compliance.



In short:
The roadmap reminds us that AI engineering isn’t just about chasing trends — it’s about mastering fundamentals, building production-ready systems, and thinking responsibly about the technology create
