Who are FDSE?

For the last 28 years and more I have been working as Solutions Engineer / Solutions Architect (SE/SA) + Professional Services / Implementation Engineer + Customer-Facing Software Engineer together combined.

Various companies I have worked on pre-sales technical scoping & integration design resembled SE/SA work or/and FDSEs inherit full production-grade coding responsibilities and Enterprise deployment & customisation tasks.

From understanding requirements from internal domain expert like here in BNY or from pre sales team of a SaaS or AI company. Never thought about what exactly my role or position is. Responsibilities always came first.

Despite being a hard-core computer science student with vast fundamental knowledge, including microprocessor architecture, operating systems, compiler design, various types of networking, protocols, and programming in various environments and languages from mainframes to microcontrollers to IoT applications. I always solve the real problem smartly. Recent years my roles named Forward-Deployed Engineer = Solutions Engineer + Implementation Engineer + Full Software Engineer, merged into one high-ownership role.

According to multiple analyses of the FDE role's evolution, especially the history of Palantir’s “Deltas” (the original forward‑deployed engineers), the modern FDE function grew out of three older roles blended together:

1. Solutions Engineer / Solutions Architect (SE/SA)

Before the FDE concept existed, companies relied heavily on Solutions Engineers or Solutions Architects to scope problems, design integrations, and work with customers during implementation.

  • These roles handled pre‑sales technical scoping, early prototypes, integration discussions, and acted as intermediaries between clients and product teams.
  • They were customer-facing, but rarely wrote large amounts of production code.

This corresponds to the FDE’s product scoping, architecture, and integration responsibilities.

2. Professional Services / Implementation Engineer

Enterprise software companies traditionally used Professional Services Engineers or Implementation Specialists for deployment and custom setup.

  • They installed systems, configured environments, migrated data, and ensured the product worked in a messy customer infrastructure.
  • This is exactly the “embedded implementation” aspect that FDEs now own.

This implementation-heavy model is referenced as the predecessor to the FDE paradigm.

3. Traditional Software Engineer (but customer-aligned)

Palantir explicitly blended full software engineering responsibilities — designing, building, debugging, and deploying production systems — into a customer-embedded role.

  • Traditional SWE: builds “one capability for many customers.”
  • Early Palantir “Delta” / modern FDE: solves “one customer’s many problems” with real production code.

This SWE component became essential because typical Professional Services or Solutions Engineers could not write and ship production-grade code, which Palantir desperately needed for complex government and enterprise deployments.

Due to not came from pure engineering background never got the opportunity or position I deserved. However, I always love the challenges to solve other facing whether customer, client or else. Continue learning and taking on challenges to learn entirely new fields and solve real problems with ownership felt great.

                                                                gemini generated A  self-contained Raspberry Pi surveillance system that: Runs autonomously (like EyeOS) — camera always active and streaming. Keeps searching for a known Wi-Fi hotspot (your phone) . Starts streaming automatically when the phone hotspot is available. Lets you view the camera feed on your phone (via browser or app). Here’s a detailed, production-ready setup: ⚙️ Step 1: Setup Raspberry Pi Camera & Software 1. Enable the camera sudo raspi-config Go to Interface Options → Camera → Enable Reboot: sudo reboot 2. Install dependencies sudo apt update sudo apt install python3-picamera2 python3-flask git -y 📸 Step 2: Create a Local Flask Streaming App Create file /home/pi/camera_stream.py : from flask import Flas...

COBOT with GenAI and Federated Learning

Image
                                                                                 generated by meta ai The integration of Generative AI (GenAI) and Large Language Models (LLMs) is poised to significantly enhance the intelligence and capabilities of cobots, taking them beyond basic automation. Here's how: 1. Enhanced Natural Language Interaction: Intuitive Communication: LLMs enable cobots to understand and respond to natural language commands, making human-robot interaction far more intuitive. Instead of complex programming, workers can simply use voice commands or text instructions. This simplifies task assignment and allows for real-time adjustments. Contextual Understanding: LLMs provide cobots with a deeper understanding of context, allowi...

AI in Education: Embracing Change for Future-Ready Learning

Image
  Executive Summary An adjunct professor advocates embracing AI in classrooms over prohibition, using historical examples of replaced skills (cursive, memorization) to argue for focusing on adaptability, creativity, and critical thinking. AI enables personalized tutoring, equity, and efficiency but demands literacy and ethics. Recommendations include shifting to debates over essays and principles over rote tasks to equip students for AI workplaces. Historical Context: Skills Evolved by Technology Education prioritizes future utility amid time constraints. Past emphases have faded: Cursive/penmanship : Graded courses in prior generations; now obsolete with keyboards—digital fluency matters more. Memorization (e.g., full periodic table) : Drills wasted time; databases provide facts—focus on conceptual understanding (e.g., element groups' properties). Manual arithmetic : Long division drills unnecessary post-fundamentals; calculators standard in higher education. Map reading : Seconda...
