The Spark
A diploma in Electronics & Communication at Sri Sairam Polytechnic. The first time a circuit on a breadboard did exactly what the maths promised.
Foundation · 9.7 CGPA

I BUILD WHAT DOESN'T EXIST.
A studio for complete systems — from embedded hardware and PCBs to communication, signal processing, robotics, AI and software.
02 — About the Engineer
I don't make websites. I design entire systems.
I'm Shivaprasad V — an Electronics & Communication engineer and the person behind SpDly Studios. I work at the seam where hardware meets signal meets software, and I am happiest when a problem has no obvious shape yet.
My practice is systems thinking: a project might begin as a question about radio noise, become a PCB, grow into a real-time pipeline, and end as a product someone can hold. Embedded firmware, communication systems, signal processing, robotics and full-stack software are simply the materials I reach for.
“Every project starts with a question. The engineering is just the discipline of answering it honestly.”

04 — The Journey
Chapters
in motion
First Silicon
Inside the Sri Sairam Techno Incubator — translating ideas into embedded prototypes and learning the craft (and humility) of PCB design.
Hardware · PrototypingThe Signal
Research that became a published conference paper: occupancy from RSSI. Meanwhile, power-electronics reliability at CE+T Power Solutions.
Research · CommsThe System
Now: studying at MIT, Anna University, and building complete systems — from satellite-adjacent comms to autonomy — as one continuous practice.

Where the
work happened
Industry, incubation and institution — each taught a different half of engineering.
2025
CE+T Power Solutions
Power Electronics & Reliability
Studied system behaviour under thermal and fault conditions; learned how reliability testing exposes the brittle parts of a design.
2024—25
Sri Sairam Techno Incubator
Hardware, Concept → Reality
Turned ideas into embedded systems and functional prototypes; discovered PCB design, signal integrity and the gap between theory and practice.
2022—25
Sri Sairam Polytechnic
Diploma, ECE
Built the foundation — electronics, instrumentation and the habit of finishing what I start. CGPA 9.7.
