AI/ML • Middle • In office, Partially remote, Fully remote • Actively seeking
Overview
Backend engineer (senior-level) focused on building LLM-backed retrieval and RAG pipelines for security workflows. The strongest proven skill is designing a hexagonal Python FastAPI service with adapters, reproducible offline eval and extensive integration tests (see app/api/app.py, app/adapters/* and app/eval/*). The public code shows limited evidence of large-scale multi-region distributed systems, long migration histories, or advanced SRE/runbook artifacts.

Overview
An iOS engineer at a solid middle level who delivers well-structured UIKit features with MVVM/presenter-interactor patterns and custom transitions. The strongest proven skill is building polished, interactive UI components and lists - evidenced by the compositional diffable collection layout (MyCode/HistoryScreen/UI/HistoryCollection/HistoryCollectionView.swift) and custom animated/interactive transitions (MyCode/HistoryScreen/PresentDismissTransition.swift). The portfolio lacks measurable performance profiling, a robust offline sync engine, extensive lifecycle-process-death handling and release/CI artifacts in public code.

Overview
A backend-focused engineer at a senior (lower-mid) level who consistently delivers well-structured prototypes and production-adjacent services across Node.js and Python stacks. The strongest proven skill is building robust API-backed tools with clear domain logic and test coverage - for example the bank-statement parsing + normalization pipeline (server/import/parseStatement.ts and server/import/normalize.ts) and the FastAPI LLM run/save/validate flow (backend/app/main.py + backend/app/models.py). Public code shows limited operational tooling and monitoring, and there is little evidence of multi-service production operations, advanced DB migration history, or formal secrets-management beyond environment variables.

Overview
A practical ML engineer at a middle level who produces hands-on notebooks, custom algorithm implementations and standard Transformer fine-tuning pipelines. The strongest proven skill is end-to-end model prototyping for classification tasks, supported by the BERT fine-tuning notebook (train_epoch/eval_model, DataLoader/tokenizer) and multiple tabular-model notebooks with preprocessing and evaluation. There is little to no evidence of production-grade MLOps, experiment tracking, deployment, or novel research in public code.

Overview
A practical frontend engineer at a middle level who builds Vue single-page app features end-to-end with Vuex and Firebase integration. The strongest proven skill is SPA state and server-integration work, demonstrated by the ads Vuex module that handles create/fetch/update flows and storage uploads (FTDen45/vue/src/store/ads.js). There is limited evidence of automated testing, measured performance optimization, accessibility beyond Vuetify defaults, or advanced architecture patterns in public code.

Overview
A practical engineer focused on building production tooling for reporting and transcription workflows at a mid-senior level. The strongest proven skill is engineering robust data+inference pipelines - evidenced by the ReportGenerator (reports_maker/apps/ipi/report_generator.py) and the LLM-backed diarization postprocessing (transcription-tool/llm_speaker_correct.py). There is little to no evidence of custom model training, experiment tracking, or large-scale MLOps (model versioning, drift monitoring) in the public code.

Backend Go developer (Middle-level) focused on building small REST APIs with clear package separation. The strongest proven skill is implementing end-to-end REST handlers and a simple data access layer, as shown by RestApi/internal/handlers/handlers.go, RestApi/internal/db/tasks.go and RestApi/api/main.go. Missing from public code are production-grade features such as tests and migration history, authentication and secrets management, structured observability, and graceful shutdown behavior.
