Hello, I’m Sachin Kottarathodi, and this is my personal page.
I am a technology professional specializing in building scalable distributed systems. I am deeply interested in distributed architectures, data-intensive systems, databases, clean code practices, and design patterns — with a strong emphasis on applying these principles pragmatically to solve real-world problems. I have a proven track record of delivering impactful business solutions, with a focus on designing maintainable and high-performance systems. My experience working with engineers across varied backgrounds has strengthened my ability to mentor, collaborate, and drive technical excellence within teams.
Beyond architecture and system design, I enjoy hands-on coding and debugging, staying close to code and systems to strengthen both technical depth and decision-making. While I thrive under pressure and responsibility, I am equally committed to maintaining a balanced approach to work and life, ensuring sustainable high performance over the long term.
For a more comprehensive list of my experience and skills, see the Resume tab.
I enjoy reading across a wide range of topics — from fiction and psychology to investment strategies. Reading helps me relax and often feels like stepping into another world, offering both a break from routine and new ways to look at things. I also enjoy writing, though I often find it easier to start than to finish. You might come across a few unfinished posts on my blog, but I find that sharing ideas — even incomplete ones — keeps them alive and makes it easier for me to revisit and finish them later. Over time, I’ve also developed a strong interest in investments and financial thinking. The Books section highlights some of the titles that have shaped my views. I appreciate value in simplicity — long walks, quiet time, and keeping life uncluttered, both in work and outside of it.
Feel free to explore the content here, and if you’d like to connect, find my links under the Contact tab.

Prompt Engineering Using Gemini API Setup from google import genai from google.genai import types client = genai.Client(api_key=GOOGLE_API_KEY) Basic Usage response = client.models.generate_content( model="gemini-2.0-flash", contents="Explain AI to me like I'm a kid." ) print(response.text) Interactive Chat chat = client.chats.create(model='gemini-2.0-flash', history=[]) response = chat.send_message('Hello! My name is Zlork.') print(response.text) Listing Available Models for model in client.models.list(): print(model.name) Model Output Settings # Max output tokens short_config = types.GenerateContentConfig(max_output_tokens=200) # High temperature for creative responses high_temp_config = types.

Prompt Engineering Notes Prompt engineering is the process of designing high-quality prompts to guide LLMs to produce accurate outputs. This involves refining length, structure, tone, and clarity. Model-Specific Setup Choose Your LLM and Configure: Model-specific prompts and capabilities Sampling parameters: Output Length More tokens = more compute cost. Reducing length just truncates output. ReAct model warning: Emits irrelevant tokens post-response. Sampling Controls Parameter Effect Temperature Low = deterministic; High = creative/random Top-K Limit prediction to top K likely tokens Top-P Nucleus sampling = choose from top cumulative probability P Num Tokens Max output length Practical Guidelines: Temperature = 0.

Sales is a Service A change in perspective. In a world that feels like a rat race—where everyone chases that extra sale, that extra attention—it’s hard to spot genuine salesmanship. Maybe it doesn’t even exist anymore? Sales and marketing strategies often feel like they’re just what’s taught in schools: a mix of human psychology twists, polished speech, hiding flaws, and putting on a smile. At the end of the day, the numbers speak loudest. Read more...

Perfection is a Sham Delayed progress Analysis paralysis Decision fatigue Brain rot Sunk cost The elephant that forgot it could move Lost motivation Burnout Discontentment “Work expands so as to fill the time available for its completion.” — Parkinson’s Law, C. Northcote Parkinson (1955) And still, perfection is sought. Craved. Chased. Worshipped. Why? Because perfection is a shield. A shield against criticism. A way to avoid failure. A distraction from fear. Read more...

This wasn’t meant to be my first post. But I wanted to start with something real. What’s happened to LinkedIn? Seriously, LinkedIn is overflowing with humble brags, pointless posts, and thinly veiled marketing. The good old “HR meets candidates” platform is now a full-blown social network. Everyone seems to have sudden epiphanies — some insightful, others… well, less so. Here’s one: learning about customer obsession from a street-side peanut vendor. Read more...
