From Zero to Maker: A Journey of Building, Breaking, and Rebuilding
I’m Lavitra Sahu — I started with a small xerox business (my first earnings), tried trading (earned, learned, and lost), got obsessed with problem-solving & coding, found my way into IoT, rocket avionics, robotics, PCB design, teaching, and constant experimentation. No filters, no perfect story — just learning through chaos, curiosity, and constant evolution.
Featured Projects
Behind every project is a cycle of building, breaking, rebuilding, and learning — sometimes it works, sometimes it teaches.

Technology Stack
Tools & Technology I have worked with…
I believe true learning happens by doing — building projects, fixing failures, learning from teammates, and sharing knowledge with others. These numbers reflect my journey of hands-on experience, not just theory.
My Journey
This isn’t the usual engineering tale. It’s a mix of failures that almost broke me, choices that raised eyebrows, and breakthroughs that reshaped my purpose. Each chapter adds up to who I’m becoming.
The Misfit Student (School Years → Early College)
Struggled with academics, constantly shifting interests between music, sports, art, and tech tinkering. Explored coding (Python, C++, C, DSA, Data Science) but never stuck for long. Started a small photocopy/printing business in parallel.
→ Learnt best by building, not memorizing
Self-DiscoveryBusiness Experiment & The Great Fall (College Years)
Scaled the photocopy/printing business and made steady profits. Shifted into stocks, F&O, and crypto trading. Overconfidence led to losses. Skipped exams and the business collapsed.
→ 100% financial loss — but gained humility & resilience
FailureThe IoT Spark
A simple IoT plant watering project turned into a learning spree with ESP32, sensors, and I2C communication. Professor Ankit Jain kept pushing with new challenges.
→ Discovered passion for building
Turning PointThe Maker Obsession
Dived into home automation, PCB design, CAD & 3D printing, Raspberry Pi, Jetson Nano, Linux, and AI projects like YOLO implementation.
→ IoT & AI projects built
GrowthHome Automation Startup
Tried launching a home automation business with strong tech but lacked capital and team coordination. Business ended quickly.
→ Lesson: Skills ≠ Business Success
FailureAI on the Edge — Jetson Nano Experiments
Ventured into edge AI using the Jetson Nano — experimenting with YOLO object detection, gesture recognition, and live camera inference. Logged every error, fix, and discovery to build a personal AI reference repository.
From setting up CUDA environments to running real-time classification, these experiments made me confident integrating AI directly into hardware systems.
→ From electronics to intelligence — learned to merge hardware and AI.
GrowthFruit Freshness Project
Built an integrated AI + IoT warehouse management system: freshness detection, OCR, brand recognition, sensors, and automated sorting.
→ First end-to-end system integration
MilestoneReaching for the Stars
Joined the Space Club under the guidance of Sandeep Khare Sir. Built robots, avionics, payloads, fiberglass rocket tubes, and composites. Led teams and taught members. Though we didn’t reach the final stages of competitions, every failure became a lesson — and we continue building for upcoming challenges.
→ Learned rocketry hands-on through failures, teamwork, and persistence
MilestoneBecoming an Educator
Conducted workshops on IoT, PCB design, avionics, and electronics. Taught hundreds of students, sparking curiosity and confidence.
→ Teaching became a source of pride
EducatorLearner of Tools
Gained hands-on experience with PCB plotter, CNC, laser engraver, bench power supply, and test equipment. Learned mechanics, precision, and control systems.
→ Learned the tools that bring ideas to life.
LearnerTeknofest & IN-SPACe / ISRO Insights
Represented our college in two national-level aerospace challenges. At Teknofest (Turkey), we designed a complete rocket avionics and payload system, cleared every major review stage, and received official approval for final launch — but failed at the second-last stage due to coordination and submission delays.
The failure was tough but transformative — it taught me that projects don’t fail because of bad circuits; they fail because of poor coordination. I learned how leadership, accountability, and clear communication matter more than technical perfection.
In the following year, we applied those lessons at the IN-SPACe / ISRO National Challenge, competing in both Rocket and CanSat categories, securing 🥈 2nd Prize (Rocket Competition) and 🏆 Best CanSat Design Award – 4th Position nationally.
→ Turned failure into a framework — learned to lead, coordinate, and rebuild effectively.
MilestoneImperfect but Progressing
Standing with projects, failures, teaching, and dreams. Still learning, still building. Preparing for the upcoming Narsimha Rocket Launch with Rocketeers — where we plan to design and test a new modular avionics system once the final launch date is announced.
Focused on translating all the lessons from Teknofest, IN-SPACe, and past builds into a more fault-tolerant, reusable flight system.
→ From zero to maker — and still on the launchpad, waiting for liftoff.
PresentMentorship & Collaboration
I’ve learned the most by building, failing, and teaching — and now I love helping others do the same. After mentoring 1000+ students in IoT, avionics, and embedded systems, I’m opening up for mentorship, collaboration, and technical guidance.
→ Available for project mentorship, student guidance, and technical advisor roles — remote or in-person.
