Work Experience
CTO & Software Engineer
ko-nect AI
- Led technical strategy and architecture, defining engineering standards, technology direction, security practices, infrastructure investment, and technical roadmaps while executing large-scale platform migrations with zero downtime.
- Designed an event-driven microservice architecture using FastAPI, NestJS, and Convex with WebSocket subscriptions, message queues, durable workflows, cron jobs, webhook ingestion, RBAC, presence tracking, and WebRTC voice and video.
- Developed and scaled distributed microservices and REST APIs using Python, FastAPI, and Node.js, defining service boundaries, API contracts, and scalable back-end architectures for core platform capabilities.
- Engineered full-stack and mobile applications using React, Next.js, and React Native, designing application architecture, reusable component systems, state management, and responsive experiences across web and mobile platforms.
- Designed database architectures across PostgreSQL, MongoDB, and Redis, optimizing data models, query performance, indexing, caching strategies, and persistence patterns for high-throughput workloads.
- Designed and managed cloud infrastructure across AWS, Kubernetes, Cloudflare, and Vercel, building automated CI/CD pipelines and deployment workflows to improve reliability, scalability, and operational efficiency.
- Architected the AI platform across RAG, vector search, multi-agent orchestration, isolated inference, token streaming, LLM integration, MCP servers, and automated code generation, establishing the architecture for scalable AI application development.
Full-stack Developer
Morio
- Architected full-stack web applications with React and TypeScript, defining front-end architecture, application patterns, and scalable component systems across the product.
- Designed and developed back-end services and APIs with Python and Django, defining core domain architecture, business logic, third-party integrations, and authentication systems.
- Designed and managed deployment infrastructure using Docker, DigitalOcean, and GitLab CI/CD, establishing automated build, deployment, environment, and release workflows.
- Established engineering quality practices through automated testing, monitoring, code review, QA processes, and production incident management, improving system stability and development standards across the product.
- Architected the back-end and IoT infrastructure for connected bike fleets, integrating GPS trackers and device telemetry with real-time location processing, fleet monitoring, trip tracking, and remote device management.
Structural Engineer
Set 4 Engineering
- Designed structural models using CAD and AutoCAD for engineering projects.
- Reviewed engineering plans, blueprints, and technical documentation and performed load calculations, structural analysis, and stress analysis.
- Analyzed structures to assess integrity, performance, and potential failure risks.
- Conducted technical and feasibility studies, including site investigations and surveying.
- Prepared technical reports, drawings, and project specifications for clients.
Full-stack Developer
Independent
- Developed and deployed web applications and platforms across multiple industries using PHP, WordPress, SQL, responsive interfaces, SEO, back-end integrations, and production hosting environments.
- Engineered cross-platform mobile applications with React Native and Flutter (Dart), integrating native modules, push notifications, offline-first storage, device APIs, deep linking, in-app purchases, app store releases, and over-the-air updates.
- Owned client engagements end to end, translating business requirements into technical architectures, selecting appropriate technologies, and delivering production-ready systems independently.
- Owned and evolved production applications post-launch, leading feature development, platform upgrades, performance improvements, bug resolution, and ongoing system reliability.
Project History
Ko-write
I architected the AI publishing pipeline as a gated orchestration of durable workflows, where each stage runs as a retryable job with its own state machine and approval checkpoint, fed by multi-source ingestion via OCR, headless browser scraping, and speech-to-text. The source material is embedded into vector indexes for retrieval-augmented generation, with generation routed across multiple large language models (GPT 5.0, LLAMA 3.1B) and schema-validated outputs to produce market analysis, book architecture, writing schedules, chapter drafts, editorial reviews, publisher matching, and marketing strategy, plus diffusion-model cover generation (FLUX.2 Pro). Full manuscripts are translated through a fan-out pipeline that segments them into chunks, runs neural machine translation and LLM refinement passes, and reassembles each chapter. All of it runs inside a real-time collaborative editor on step-based document synchronization, backed by a paginated typesetting engine for multi-format publishing.
ID Cad Pro
I architected the 3D dental AI pipeline, which ingests intraoral scans in STL, PLY and OBJ, CBCT volumes in DICOM, and clinical photography. Deep-learning mesh and point-cloud models perform tooth segmentation and FDI numbering, margin-line detection, occlusal clearance and undercut analysis, insertion-axis estimation, bite registration, and shade matching, while vision-language models produce JSON-schema-constrained clinical reports. The pipeline drives AI-assisted design of crowns, onlays, and veneers: generative proposals from anatomical tooth libraries, parametric control of contact points, emergence profiles, cement gap and material thickness, and CAM-ready mesh export for milling and 3D printing, all in a WebGL/Three.js viewer with measurement, sectioning, and annotation.
