I work end-to-end on web products — from database schema and API design through deploy pipelines and the UI on top. The list below is what I most often get hired for. Engagements are typically scoped per-project; recurring retainer arrangements are available for ongoing work.
If your problem doesn't match a heading exactly, get in touch — most full-stack work falls somewhere in this neighborhood.
SaaS Product Development
End-to-end product engineering for early-stage and growth-stage SaaS companies. I take a feature, an idea, or a half-built MVP and ship it as a real, billable product.
- Multi-tenant architecture (org switching, per-tenant data isolation)
- Authentication, role-based access control, audit logs
- Stripe billing, subscription lifecycle, webhook reconciliation
- Onboarding flows, email transactionals, usage tracking
Stack: Next.js, Node.js, Express, MongoDB or PostgreSQL, Redis, Stripe, AWS / Vercel.
Custom Web Applications
Full-stack web apps built to spec — internal tools, customer portals, marketplaces, content platforms. Anything that's more than a static site and less than a multi-product platform.
- SSR / ISR / static generation strategy chosen per page
- Real-time features via WebSockets or server-sent events
- Third-party integrations (CRMs, payment, mapping, OAuth providers)
- File uploads, media processing, signed URLs
Stack: React, Next.js, TypeScript, Node.js, Tailwind CSS, Prisma.
REST API Design & Development
Backend services designed to be consumed by web, mobile, and third-party clients. Versioned, documented, observable, and rate-limited from day one.
- Resource modeling and endpoint design
- OpenAPI / Swagger specifications
- Rate limiting, request validation (Zod / Joi), error contracts
- API keys, OAuth 2.0, JWT with refresh-token rotation
- Logging, metrics, and tracing wired to your observability stack
Stack: Express, Fastify, Node.js, TypeScript, MongoDB, PostgreSQL, Redis.
Admin Dashboards & Analytics
Operational tools that turn raw data into decisions — for ops teams, support, and internal stakeholders. Charts, tables, exports, and the boring-but-critical workflow screens.
- Real-time charts and live-updating tables
- Cohort, funnel, and retention queries with materialized rollups
- CSV / JSON / report exports
- Saved views, segments, and shareable URLs
- Audit trails and full action history
Stack: React, Next.js, Recharts / D3, server-side aggregation in Node + Postgres / Mongo.
Database Design & Optimization
Schema design before the feature ships, performance tuning when it doesn't. I treat the database as a first-class part of the architecture rather than something the ORM hides.
- Schema modeling for MongoDB and PostgreSQL
- Indexing strategy, query plan review, slow-query elimination
- Migration strategies (zero-downtime, expand/contract)
- Read replicas, connection pooling, caching layers
Performance & Scalability Audits
A focused engagement to find the bottlenecks slowing your app down — frontend or backend. You get a written report with prioritized fixes and, if you want, the implementation that follows.
- Lighthouse / Web Vitals audit, bundle analysis, image strategy
- API latency profiling, N+1 detection, query plan review
- Caching audit (CDN, Redis, in-memory) and cache-key design
- Load testing and capacity planning
Architecture & Code Review
Senior engineering review for teams without one — or a second opinion before a major rewrite. Useful when you need to make a load-bearing decision and want a sanity check from outside the team.
- Architecture review (boundaries, coupling, data flow)
- Code review across PRs or whole repos
- Migration planning (REST → GraphQL, monolith → services, frameworks)
- Hiring rubrics, technical interview prep, take-home review
Maintenance, Refactoring & Upgrades
Existing app, accumulated tech debt, dependency rot, framework upgrades. The unglamorous work that keeps things shippable.
- Major-version upgrades (Next.js, React, Node) with migration plans
- Targeted refactors with tests written before the change
- Dead-code removal and dependency pruning
- TypeScript adoption in legacy JavaScript codebases
How Engagements Work
- Discovery call — we walk through what you need, what's already in place, and what success looks like.
- Proposal — fixed-scope statement of work with deliverables, timeline, and price, or a weekly retainer for ongoing work.
- Build — I work in your repo, against your conventions, with whatever cadence fits your team (async-first, daily standups optional).
- Handoff — code, docs, and a walkthrough. Optional support window included.
