About me

Senior Software Engineer with experience building backend services, developer platforms, and production TypeScript/Rust systems. I work across service implementation, React/TypeScript application infrastructure, build tooling, internal libraries, and deployment environments.

My recent work has focused on turning product requirements into maintainable platform pieces: Rust backend services, typed client libraries, validation/data pipelines, documentation tooling, test/build infrastructure, and Nomad/Consul/Vault-based deployments.

I am most effective in engineering roles that require ownership beyond feature delivery: designing boundaries, improving reliability, reducing operational friction, and building systems that other engineers can understand, use, and extend.

Senior Software Engineer · Oxdev

Platform/backend engineer for education management products. Responsible for Rust services and platform libraries, TypeScript developer infrastructure, internal documentation/tooling, validation/runtime systems, and deployment automation across Nomad/Consul/Vault-based infrastructure.

- Built and maintained a large Nx/Bun monorepo with React 19, Next.js, Modern.js, Rsbuild/Rspack, Storybook, Playwright, and shared internal packages
- Developed Rust backend services and platform libraries with Axum, Tokio, aide/OpenAPI, SeaORM/SQLx, typed service layers, object storage, auth/middleware, localization, pagination/filtering, and Testcontainers
- Built reusable TypeScript infrastructure around typed clients, Effect HTTP, serialization, auth/session handling, observability, datatables, data-entry surfaces, and validation flows
- Developed Rust DSL/runtime components for validation and transformation pipelines, including parser/core value modeling, runtime modules, code generation, regex support, CLI tooling, and WASI/browser Wasm bindings
- Worked on deployment automation and operational debugging across Nomad, Consul, Vault, Nomad Pack, Terraform, Ansible, Postgres, object storage, service discovery, secrets, and ingress/service-mesh issues

Product platforms

Worked on education management products and adjacent operational tools, including public-facing and administrative React applications, data-heavy interfaces, workflow screens, and input-heavy user journeys.

Rust backend platform

Developed Rust crates and backend services around Axum routers, aide-generated OpenAPI surfaces, SeaORM/SQLx data access, typed CRUD/service boundaries, object-storage APIs, auth extractors, localization middleware, pagination/filtering, and integration-test support.

Developer platform

Built shared TypeScript libraries, frontend infrastructure, package documentation, test utilities, build tooling, and cross-runtime helpers used by multiple product teams and applications.

Rust DSL and validation pipelines

Developed Rust-based DSL/runtime components for validation and transformation pipelines, including lexer/parser/core value modeling, runtime and standard-library modules, code generation, regex support, CLI tooling, and WASI/browser Wasm bindings.

Documentation platform

Built an internal documentation platform for workspace packages and platform knowledge, with modular rendering, dynamic package metadata, and internally authored technical documentation.

Infrastructure and delivery

Worked on deployment automation with Nomad, Consul, Vault, Nomad Pack, Terraform, Ansible, Go tooling, GitLab CI configuration authored with Dhall, object storage, Postgres, service discovery, secrets, and ingress/service-mesh debugging.

Freelance Software Engineer · Freelance

Delivered full-cycle software projects across AI/ML data operations, internal tooling, computer-vision capture flows, analytics dashboards, automation, and market-research systems.

- Built backend services, frontend applications, admin dashboards, data capture workflows, deployment setups, and integrations with third-party APIs
- Worked with Python/FastAPI and Django backends, TypeScript/React frontends, WebSocket data streaming, background workers, object storage, and containerized deployments
- Developed browser-based webcam/video capture experiences for AI/ML datasets, including multilingual task flows, liveness/quality feedback, and assignment-style submission lifecycles
- Built internal tools for task assignment, team/project management, productivity visibility, and operational data review

AI/ML data collection platforms

Built platforms for collecting and validating browser-submitted image/video data, including FastAPI services, WebSocket frame ingestion, React capture UIs, assignment/session lifecycle handling, background workers, object storage, and operational monitoring.

Computer-vision capture frontends

Implemented TypeScript/React webcam applications for liveness and face-capture workflows, including camera/device handling, timed multilingual instructions, canvas/video processing, MediaPipe/TensorFlow.js face landmarks, guided pose capture, and upload flows.

Productivity and operations tooling

Developed internal tooling for a data-processing company, including a productivity enhancement/tracking browser-extension workflow in TypeScript, backend services for task/session data, and dashboards for managers to coordinate people, projects, status, and review work.

Fitness route and activity platform

Built a map-heavy route generation product with a Python backend and React frontend: async route processing, elevation and timing modeling, generated activity exports, progress streaming, Strava integration, and Nix/containerized deployment setup.

Market research automation

Authored asynchronous Python scraping tools for public product/review data, using typed models, concurrency limits, HTTP/browser scraping, structured extraction, and file-based outputs for analysis.

Analytics and workflow automation

Built smaller full-stack and automation projects, including social-data analytics dashboards with Python/React, ML/NLP experiments, REST APIs, authentication, Telegram workflow automation, and maintenance of existing customer services.
