R&D and Deep Tech

Engineering Lab

Architectural experiments, performance benchmarks, and custom developer tooling built to solve non-trivial software challenges.

EXPERIMENT #01 • CAD ENGINE

Vector Drawing & Rebar Detailing

Custom vector generation pipeline producing millimeter-accurate structural drafting viewports, lap zones, and confined tie dimensioning directly to PDF and interactive canvas.

EXPERIMENT #02 • HIGH CONCURRENCY

ASGI Microsecond Optimization

Tuning Python FastAPI with Uvicorn workers and PostgreSQL connection pooling to sustain heavy concurrent exam query loads with minimal memory footprint on constrained VPS nodes.

EXPERIMENT #03 • OFFLINE SYNC

Deterministic Multi-Device Sync

Conflict-free offline synchronization protocol between client-side SQLite databases and authoritative server backends, ensuring zero progress loss during network dropouts.

EXPERIMENT #04 • GOVERNANCE

Originality & Similarity Forensics

Automated multi-stage forensic auditing pipelines validating copyright provenance, semantic originality, and syllabus alignment across thousands of pedagogical assets.

Profile & Philosophy

Engineering for Durability & Precision

I design and build software systems with a simple guiding principle: eliminate ambiguity and optimize for resilience. Whether structuring educational platforms reaching thousands of students or automating complex structural engineering workflows, I prioritize clear boundaries, deterministic outputs, and clean operational architecture.

My background bridges the entire stack: low-level server configuration, database schema design, high-concurrency microservices, and reactive mobile interfaces that feel effortless to end users.
