[03] Featured Work

Flagship systems with engineering context.

The strongest projects are treated as case-study modules: problem, build, technology, and grounded outcome.

Solana / Market Intelligence

Solana Market Lab

In Developmentprototype

A product lab for Solana market intelligence and tooling.

Problem

Solana market and product builders need clearer interfaces for signals, tooling, and evidence.

Built

A prepared project profile for market tooling and product research workflows.

Impact / Result

Included as current build direction without fabricated metrics or implementation claims.

  • Solana
  • Analytics UX
  • Product research
  • Market tooling
Industrial Engineering / Predictive Maintenance

SOGEA Predictive Maintenance

Case Studycase-study

Predictive maintenance case study for industrial welding equipment.

Problem

The cage-welding machine needed clearer fault prioritization, earlier warning logic, and maintainable maintenance workflows.

Built

A DMAIC-based reliability workflow with FMEA, fault prioritization, monitoring concepts, CMMS mapping, and a Random Forest proposal.

Impact / Result

Grounded engineering case study with priority fault families, RPN analysis, sensor strategy, and maintenance action design.

Automotive Engineering / ECU Tooling

TT Tune

In Developmentprototype

A safety-first workflow for ECU analysis and tuning-readiness.

Problem

ECU workflows need traceable analysis, file integrity, and safety constraints before calibration work can be trusted.

Built

A scoped prototype covering binary upload, metadata analysis, map decoding direction, validation, patch manifests, and integrity checks.

Impact / Result

Frames ECU tooling as engineering safety and readiness instead of unrestricted tuning claims.

Solana Infrastructure / Analytics

NodeScope

In Developmentprototype

Infrastructure observability for Xandeum pNode operations.

Problem

Infrastructure operators need node-level signals presented as usable operational context.

Built

A pNode-oriented dashboard concept for network status, node signals, and reviewer-friendly analytics.

Impact / Result

Keeps infrastructure analytics scoped until live data integrations are confirmed.

Solana / DeFi Analytics

MeteorScope

Public Betabeta

Meteora DLMM wallet, pool, and transaction analytics.

Problem

Meteora DLMM users and builders need clearer inspection of wallets, positions, pools, and failed transactions.

Built

Wallet analysis, position inspection, pool explorer, transaction diagnostics, token normalization, fallback RPC, and readiness endpoints.

Impact / Result

Public beta and open-source project with live product evidence.

  • TypeScript
  • Solana Web3.js
  • Meteora DLMM SDK

  • Upstash
  • Vercel
AI / Solana Transaction Infrastructure

SolFix AI

Livelive

Agentic Solana transaction debugging and repair guidance.

Problem

Failed Solana transactions are hard to understand without instruction-level reconstruction and clear repair context.

Built

Transaction signature and serialized transaction analysis, instruction-tree reconstruction, explanation providers, persistence, and public reports.

Impact / Result

Open-source Solana AI tooling focused on diagnosis and guidance, not automatic transaction modification.

Industrial Problem

A production machine needed a clearer reliability workflow around recurring faults and maintenance decisions.

Method

The work used DMAIC, FMEA, MTBF / MTTR reasoning, and RPN-based prioritization.

System Design

Monitoring concepts covered temperature, vibration, pressure, and IoT data collection.

Predictive Logic

A Python Random Forest classifier was proposed as part of the condition-analysis layer.

Operational Outcome

The project connected fault analysis to preventive maintenance, CMMS workflows, and actionable inspection routines.

  • FMEA
  • IoT monitoring
  • Temperature monitoring
  • Vibration monitoring
  • Pressure monitoring
