555 Labs is Michael Blonsky — an independent software consultant with deep experience shipping Python/Django backends and Firebase/React products.
Michael has spent years building and scaling web applications across industries — from early-stage startups to established product teams. He brings a pragmatic, quality-first approach to every engagement: clean architecture, readable code, and a bias toward shipping.
He's also deeply experienced with the current generation of AI tools — Claude (Anthropic), ChatGPT (OpenAI), and Gemini (Google) — integrating LLM APIs into production Django and React applications, building RAG pipelines, and designing agent workflows that actually work in the real world.
When you work with 555 Labs, you work directly with Michael from day one. No handoffs, no middlemen — just focused execution on your project.
Working with an independent consultant means you get an expert — not a junior billed at a senior rate.
Every line of code is written by an experienced engineer, not delegated down to a team of juniors after the sale.
You talk to the person doing the work. No account managers, no translation layers, no status games.
Years of specialization in Python/Django and Firebase/React — not a generalist who Googles your stack after signing.
Clean, well-documented code with tests. When the engagement ends, your team can run and extend it independently.
No long sales cycles. Discovery to kickoff in days, not weeks. When you need to move, 555 Labs moves with you.
Auth, permissions, and data handling are treated as first-class concerns — not an afterthought bolted on at the end.
Still curious? Reach out directly — happy to chat.
555 Labs works with startups, scale-ups, and product teams of all sizes. Projects range from a focused two-week feature build to multi-month product engagements. The sweet spot is 1–6 month scopes where deep technical expertise adds the most value.
Absolutely. Many clients bring in 555 Labs to complement an existing team — filling a stack-specific gap, accelerating a critical feature, or providing a senior review layer. Git, PRs, and code reviews are standard practice.
NDAs and IP assignment agreements are standard for every engagement. All code and business information is kept strictly confidential. 555 Labs has no interest in your trade secrets — only in delivering great work.
555 Labs operates in US timezones and collaborates with clients worldwide. Async-first communication keeps things efficient, with overlap hours available for live syncs and demos.
It's a 30-minute intro focused on understanding your problem, current stack, and timeline. No slides, no pitch — just a practical conversation. You'll leave with a clear sense of whether 555 Labs is the right fit and next steps.
Yes. Common migrations include moving from monolith to microservices, Firebase to Django (or vice versa), REST to GraphQL, and legacy jQuery apps to React. These are scoped carefully to avoid big-bang rewrites.
